When I try to install mysql-server, an error comes like:
dpkg: error processing package mysql-server (--configure):
dependency problems - leaving unconfigured
Errors were encountered while processing:
mysql-server-5.7
mysql-server
E: Sub-process /usr/bin/dpkg returned an error code (1)
What does it mean. Any ideas?
dpkg returning an error code 1 doesn't mean anything specific but it usually has to do with dependency issues. In your case, you tried to install two versions/instances of the same package i.e. mysql-server and mysql-server-5.7. So do the following to remove any redundant dependency issues and install a functioning mysql package
sudo apt-get clean
sudo apt-get purge mysql*
sudo apt-get update
sudo apt-get install -f
sudo apt-get install mysql-server-5.7
sudo apt-get dist-upgrade
this should fix the problem at hand. But in the future, have care about the package names you add after sudo apt-get install since the wrong list of package names - for example redundant entries in the list - results in failure to install either of the packages or worse - you might even find yourself wading through the hellish depths of #DEPENDENCY-HELL
All of the answers I've been able to find for this question have been of the form "purge your Mysql install and re-install it." But in my case, I already have a working/active Mysql install. For me, the reason why dpkg --configure -a fails is because Mysql is already installed. Why dpkg thinks that the postinstall script needs to be run for my already-installed-and-upgraded Mysql I may never know, but it does.
After considerable time scouring for answers, I found a solution that should work if there are others who already have a working Mysql 5.7 and just want to get past this bogus postinstall script. You can edit the postinstall script directly as (on Ubuntu):
sudo vi /var/lib/dpkg/info/mysql-server-5.7.postinst
And then, on the second line, just add exit 0 and then run dpkg again and you should get something like:
$ sudo dpkg --configure -a
Setting up mysql-server-5.7 (5.7.28-0ubuntu0.18.04.4) ...
You definitely would not want to follow these instructions if your Mysql installation had not previously completed (there's a reason that the postinstall script insists on running). But for those who might end up with dpkg in a wonky state, as I have, the above can save you a lot of time purging and reinstalling an already-working version of Mysql.
This should help
sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get dist-upgrade
And now reinstall mysql
sudo apt-get install mysql-server
If you're on a VPS or similar, your error may be due to lack of RAM.
Running apt-upgrade seems to require some RAM, so it may force-close mysql, hence the problem to recover from the error.
Try:
1) Stop mysql manually before any apt-upgrade
sudo /etc/init.d/mysql stop
2) Fix:
sudo dpkg --configure mysql-server-X.X
(if version not known, use just mysql-server to find out (will not fix error)
3) Check:
sudo apt-get upgrade
Start mysql manually if it wasn't started by apt.
I had a similar issue. This is how I fixed mine.
Restart MySQL service sudo service mysql restart
Then fix broken installations sudo apt install -f

kill the musql deamon and purging helps
sudo pkill mysqld # kill
sudo apt-get purge mysql-server-5.7 # Or whatever you are trying to purge.
Thanks, #endrias for the suggestion.
Old Answer
None of the apt methods worked for me, try this:
Find locking process
$ ps -eaf
root 7316 1 0 00:19 ? 00:00:00 /usr/bin/dpkg --status-fd 35 --configure --pending
root 7808 7316 0 00:19 ? 00:00:00 /usr/bin/perl -w /usr/share/debconf/frontend /var/lib/dpkg/info/mysql-se
root 7817 7808 0 00:19 ? 00:00:00 /bin/bash /var/lib/dpkg/info/mysql-server-5.7.postinst configure
mysql 7973 7817 0 00:20 ? 00:00:00 mysqld --user=mysql --init-file=/var/lib/mysql-files/tmp.iNyY06ty0K --so
Kill it
do sudo kill -9 7973, basically the mysql one.
Now purge
sudo apt-get purge mysql-server-5.7 # Or whatever you are trying to purge.
i face same error due to problem in my upgrade from ubuntu 18.04 to ubuntu 20.04 , what i did is get mariadb instead also make sure when you do pruge mysql that if asked you to remove dbs in the dir
tell it not to delete the dbs so you will have your old databases with no data loss
what i did was this cmds
sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get dist-upgrade
sudo apt-get install mariadb-server
I tried almost every possible way but nothing was working for me. Then I found the problem that I was facing was due to less available ram. You can check your current ram status by free -h (in my case available was less than 1 GB). To clear ram restart your device. Then type following commands
sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get dist-upgrade
then again install mysql-server by
sudo apt-get install mysql-server
try this solution using aptitude this will replace all the file corrupted.
This is work on my 18.04

In my case I had to run:
systemctl stop mysql.service
to stop MySQL before being able to install mysql without errors using:
sudo apt-get install mysql-server
To solve the dependency issue, try:
sudo apt-get purge
sudo apt-get clean
sudo apt-get check
And reinstall the package again by: sudo apt-get install mysql-server.
Source: Thread: Dpkg: Dependency problems - leaving unconfigured.
Other commands to try:
sudo apt-get install -f
sudo apt-get autoremove
sudo dpkg --configure -a
Related: How can I Resolve dpkg dependency? at Ask Ubuntu.
The problem can be much simpler (in my case) I had a missconfigured value in my configuration file [my.cnf] which lead to the error.
After cleaning up my.cnf mysql-server was restarted successfully
If you are working on Debian 10, you need to first install GNUPG:
sudo apt-get install gnupg
That's all; now you can try dpkg again.
Also pay attention to the terminal you are using, if it is ZSH many uninstall commands will not work like: sudo apt-get purge mysql* and the reinstallation process will fail, to fix this it is simple type in your terminal the word bash so that the terminal used is Bash, run the sudo apt-get purge mysql* command again and also the following commands below to confirm that you removed everything.
sudo apt-get remove mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean
sudo rm -rf /var/lib/mysql
sudo rm -rf /etc/mysql
Finally, run mysql --version to make sure there is no version on your machine and you can try installing again.
I came across the yes Unix binary, which is incredibly stupid: it just endlessly types y (try it, you can just run yes in your terminal)
so the following just works (I used this in a dockerfile)
yes | apt-get install mysql-community-server
I had another mysql process running in background.
(ckeck if your lampp mysql server is on, Then turn it off.)
then try
sudo apt dist-upgrade
if lammp mysql is not working then,
check this command,
ps -eaf
and then look for mysql process and kill it by it's port number
sudo kill -9
I was in the same situation. After completely removing MySQL, I reinstalled it, killed the PID using port 3306, and reinstalled MySQL again. It's working now.
I prepared and tested a dockerfile before sending it to a client, on whose machine, the build process is running into apt-get errors.
Here is a of some of the package download failures.
It doesn't seem to be a proxy issue since most packages, and some wgets, are working fine. I'm not getting any such errors on my own machine, so I'm at a loss as to how to go about debugging the problem. Any leads?
I am particularly curious what the 400 bad request error indicates. Does it have something to do with the 404 leading up to it?
EDIT: Here is a link to the Dockerfile.
Had this happen to a co-worker. The only thing we change was
RUN apt-get update -y && apt-get install ...
TO
RUN apt-get update -y && apt-get upgrade -y && apt-get install -y
I tried all sorts of things, but this was the only thing that worked for me.
I would like to install MySql 5.7 on Debian 7 Wheezy. I put :
deb http://repo.mysql.com/apt/debian/ wheezy mysql-5.7
in file:
/etc/apt/sources.list.d/mysql.list
Next I run commands:
sudo apt-get update
sudo apt-get upgrade
And tried install package:
sudo apt-get install mysql-server-5.7
I got an error:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting 'mysql-community-server' instead of 'mysql-server-5.7'
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
mysql-community-server : Depends: mysql-common (= 5.7.11-1debian7) but 5.5.47-0+deb7u1 is to be installed
Depends: mysql-client (= 5.7.11-1debian7)
E: Unable to correct problems, you have held broken packages.
Do you have any ideas to resolve this problem?
I also tried:
Note, selecting 'mysql-community-server' instead of 'mysql-server-5.7'
But it's not the solution of the problem.
I stumbled upon this post and can confirm simply changing the priority of your cache by downloading the .deb package directly from MySQL Downloads
Using the command line:
$ cd /usr/src && sudo wget http://dev.mysql.com/get/mysql-apt-config_0.7.3-1_all.deb
Please note: by convension the /src directory on linux exists for source code to live before being compiled - I believe the deb package above therefore belongs here.
This works for Debian/Wheezy.
$ sudo dpkg -i http://dev.mysql.com/get/mysql-apt-config_0.7.3-1_all.deb
Once this you have gone through the steps, you simply hit Ok, and then proceed to install mysql-server like normal:
$ sudo apt-update
$ sudo apt-get install mysql-server
For me, this resulted in the following:
[info] MySQL Community Server 5.7.14 is started.
Setting up mysql-server (5.7.14-1debian7) ...
Further reading, if you ever want to remove this package, you can do so:
$ cd /usr/src && sudo dpkg --remove http://dev.mysql.com/get/mysql-apt-config_0.7.3-1_all.deb
As of 2020 with Debian Wheezy 7.11 the answer doesn't work anymore. I had to change a few things and thought it might be useful to share the result:
Install mysql-apt-config_0.8.10-1_all.deb (Version 0.8.15-1_all won't work: dpkg can't handle the "control.tar.xz" it contains.)
cd /usr/src
sudo wget https://dev.mysql.com/get/mysql-apt-config_0.8.10-1_all.deb
sudo dpkg -i mysql-apt-config_0.8.10-1_all.deb
This will create the necessary /etc/apt/sources.list.d/mysql.list file.
sudo apt-get update
sudo apt-get install mysql-server
Thanks goes to David Kehr from where I got the working mysql-apt-config version.
You don't need to specify the version in the apt-get command, just type :
sudo apt-get install mysql-server
After the install, you can type the following command to check mysql version
aptitude show mysql-server
On my machine I have the following result :
...
Version : 5.7.13-1debian7

I have to change my databasefrom MySQL to postgreSQL in django. But postgreSQL is not installing .

The following packages have unmet dependencies:

E: Unable to correct problems, you have held broken packages.
but its not working.how can i do this.and what changes i have to made. Plz help
aptitude might be able to resolve this issue. It's a more sophisticated dependency management tool than apt-get.
You may install it with apt-get:
sudo apt-get install aptitude
You may use aptitude to install postgresql
sudo aptitude install postgresql-9.3
If aptitude encounters any problems it automatically devises a possible solution to install this package. Be aware that aptitude might suggest remove conflicting packages. So if you get prompted by aptitude please read the prompt carefully.
I am using Ubuntu 14.04. sudo apt-get update always give me this option to configure mysql-apt-config.
I am have tried to select the version, press 'tab' -> key highlighted on 'OK', press 'Enter' but nothing happens. It goes back again highlighting the version number.
Software Updater also crashes at mysql-apt-config.
Any idea on what is causing this problem and how to get rid of it? Thx.
When you can't do
apt-get purge mysql-apt-config
because you're trapped: It won't execute because dpkg is interrupted, and "sudo dpkg --configure -a" backs you to the broken "configuring mysql-apt-config" screen...
edit: /var/lib/dpkg/info/mysql-apt-config.postinst
add exit at the beginning , then get rid of the package :
sudo dpkg --configure mysql-apt-config
sudo apt-get remove mysql-apt-config
Unistall current packages
$ sudo apt-get remove mysql-server mysql-client mysql-common
$ sudo apt-get autoremove
$ sudo apt-get autoclean
Install dependency: sudo apt-get install libaio1
Download the currect mysql-apt-config<version>.deb for your installation from http://dev.mysql.com/downloads/repo/apt/.
Install into your system: sudo dpkg -i mysql-apt-config<version>.deb
Instal mysql server: sudo apt-get install mysql-server
With regards to the CUI (character user interface):
highlight the version you want (using arrow keys)
press 'Enter'
This should take you back to the list of packages (i.e. not the list of version numbers). Then:
highlight 'Apply' (using arrow keys)
press 'Enter'
