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 have never installed mariadb on my device. Why is this error reported? I need to install mysql server on my device.
Please help me.
remove mariadb with
apt remove mariadb-common
then install mysql did it for me
By wrong uninstalling MariaDB, I've lost working instance of MySQL and MariaDB in my Ubuntu 16.04 system...
I've broken the dependencies so much, that I can not uninstall or install MySQL or MariaDB, using apt-get, or dpkg...
All the following commands failed:
apt-get [install -f] [update] [remove] [purge] [autorove] [clean] [check]
and options with dpkg such as:
dpkg --remove --force-remove-reinstreq mysql
also don't help me.
Manually downloading the package and attempting to install from a local file did not help.
For each installation, uninstallation or other attempt, I get almost the same result:
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
mariadb-client : Depends: mariadb-client-10.0 (>= 10.0.34-0ubuntu0.16.04.1) but it is not installed
mariadb-server-10.0 : PreDepends: mariadb-common (>= 10.0.34-0ubuntu0.16.04.1) but it is not installed
Depends: mariadb-client-10.0 (>= 10.0.34-0ubuntu0.16.04.1) but it is not installed
Breaks: mysql-server
mariadb-server-core-10.0 : Depends: mariadb-common (>= 10.0.34-0ubuntu0.16.04.1) but it is not installed
mysql-server : Depends: mysql-community-server (= 5.7.22-1ubuntu16.04) but it is not installed
E: Unmet dependencies. Try using -f.
Is there any different way to permanently remove any traces and remnants of MySQL and MariaDB from the operating system, so that I can reinstall MySQL itself?
I need to working with MySQL, but I can't reinstall the operating system.
Please help me.
God exists! :D
The problem was solved by entering:
sudo apt-get -f install
without any other parameters
and later displaying all packages via:
sudo dpkg -l | grep mariadb
sudo dpkg -l | grep mysql
and removing problematic packages in the right order:
sudo apt-get --purge autoremove package_name
After the complete removal of all problematic packages, I could re-install MySQL without any problems...
Thank you #YuriLachin for your help.
It is probably better to address the question to serverfault.com.
Run:
dpkg --audit
to find what is broken.
Then run:
dpkg --list|grep -i mysql
and
dpkg --list|grep -i mariadb
Look at the first (status) column and, optionally, inspect detailed status for some of packages with:
dpkg-info -s <name-of-package>
Then you can try to remove found mysql/mariadb related packages with
dpkg -remove --force-remove-reinstreq <package-list>
As a way around you can always run mysq in docker container without mysql being installed

its installing the previous version instead of new version.
so please help me
try this:
sudo apt-get purge mysql-server
This worked for me in Linux mint 20
sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
apt automatically installs the latest version available in the added repositories.
to see all the available versions in your enabled repositories, run
apt-cache policy mysql-server
if the version you want to install is not listed in the output, then you might need to add extra repositories.
Coming to 254 not upgraded part, it just means that updates for 254 packages are available in the repositories.
You can install those updates using
sudo apt-get upgrade
Please try using this command to remove MySQL completely from your current Linux system including your databases, settings and everything else.
sudo apt-get purge mysql
Hopefully I didn't mistyped :p
Let me know if it worked for you.
Try uninstalling it from software manager and restart the system, it worked for me.
Execute the following command :
# rpm -qa | grep mysql
It will list all installed mysql packages on your system. Eg: mysql-libs-5.1.73-3.el6_5.x86_64
now execute the command:
# yum remove <name displayed in above step-1>
Eg: yum remove mysql-libs-5.1.73-3.el6_5.x86_64
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

The following information may help to resolve the situation:
The following packages have unmet dependencies:

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
