I am unable to install mysql server on my linux-20.4 machine.I get the following error:
The following packages have unmet dependencies:
mysql-server : Depends: mysql-community-server (= 8.0.27-1ubuntu20.04) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I have tried deleting and then reinstall several times but got the same result.Then i tried to manually install all the packages. But I got stuck in libaio1 and libmecab2. I did apt-get upgrade but still
get the error : Package 'libaio1' has no installation candidate.
This is the first time I am installing mysql.Also I am new to linux.May be I didn't delete existing mysql completely.Please help me install mysql.
Try to install mysql-common and mysql-community-client-plugins both on a single command. It will fix the issue.
sudo apt install mysql-community-client-plugins mysql-common

Fetching mysql2 0.5.2
Installing mysql2 0.5.2 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
To solve this I ran following.
gem install mysql2 -v '0.5.2' --source 'https://rubygems.org/'
Then got the following error.
mysql client is missing. You may need to 'apt-get install libmysqlclient-dev'
now I am stuck and found no solution working. tried google and all other option but no suggestion is working for me.
Unable to locate package libmysqlclient-dev
To give you proper answer as I found that all comments are to the point, but I wanted to check if really such issue exists. So I spin up new ubuntu server 16.04 and used following commands to installd mysql gem. I used rvm to install ruby
sudo apt-get update
sudo apt-get install mysql-server
sudo apt-get install software-properties-common
sudo apt-add-repository -y ppa:rael-gc/rvm
sudo apt-get update
sudo apt-get install rvm
Now relogin to terminal to rvm command can start with its environment
rvm install ruby 2.6.3
Now I used ruby -version to check I am using same version as you were so got response ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-linux] Now I used following command to install gem. If it succeed then rails will be also installed.
gem install mysql2 -v '0.5.2' --source 'https://rubygems.org/'
But I am getting same error as yours, now let us solve it as it is saying us how to solve error. This error is already giving me information what should I do. It told me to install following package
apt-get install libmysqlclient-dev
And now I tried again and it worked. Hope it will resolve your issue. If you still have issue, than you can try by removing mysql packages you install and reinstall using these commands.
I tried installing mysql client using pip install mysqlclient but ended up as
#include "Python.h"
^~~~~~~~~~
compilation terminated.
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
So I tried installing packages that could detect header file Python.h
For that I tried sudo apt-get install python3.6-dev
But that resulted into
The following packages have unmet dependencies:
python3.6-dev : Depends: python3.6 (= 3.6.6-1~18.04) but 3.6.6-1+xenial1 is to be installed
Depends: libpython3.6-dev (= 3.6.6-1~18.04) but it is not going to be installed
Depends: libpython3.6 (= 3.6.6-1~18.04) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
How to deal with this situation and where the problem lies?
It seems you are having dependency issue. Install libpython3.6-dev then python3.6-dev and mysql. After that I hope you will be able to install mysqlclient.
sudo apt install libpython3.6-dev
sudo apt install python3.6-dev
sudo apt instal mysql-server
Then you will be able to install mysqlclient.
**if this does not happen it's good to uninstall and reinstall the python3.6 because many people got solution in this way. You can can see here
You may use following commands to do that and repeat those above commands.
sudo apt purge libpython3*
sudo apt-get purge python3.6
sudo apt-get autoremove && sudo apt-get autoclean
sudo apt-get install python3.6*
Hope it will sove your problem.
I get this error from Inspircd
Can't exec "mysql_config": No such file or directory at /home/alpha/inspircd-2.0.19/make/utilities.pm line 392, <FLAGS> line 37.
Make sure you have pkg-config installed
In the case of gnutls configuration errors on debian,
Ubuntu, etc, you should ensure that you have installed
gnutls-bin as well as libgnutls-dev and libgnutls.
I've been looking all over the internet trying to find out how to remove the errors.
I have read multiple threads but no luck. I know I need the libmysqlclient-dev package but I can't for the life of me get it installed.
I run
sudo apt-get install libmysqlclient-dev
Also tried cleaning, "-f" and so on but I still get the error.
The following packages have unmet dependencies:
libmysqlclient-dev : Depends: libmysqlclient18 (= 5.5.40-0ubuntu1) but 5.5.41-0ubuntu0.14.04.1 is to be installed
E: Unable to correct problems, you have held broken packages.
I tried it with aptitude
sudo aptitude install libmysqlclient-dev
then I downgraded libmysqlclient18 one version and now it works as it should.
you tried remove all PPA ( Personal Package Archive )?
before try:
sudo apt-get autoremove && sudo aptitude update && sudo aptitude install libmysqlclient-dev
I see in Bugtrack MYSQL:
https://goo.gl/34NUgo
your ERROR is Bug know Bug #73522 Installation of libmysqlclient-dev fails if libmysqlclient18 is from percona
still unsolved:

att
Have you tried tu upgrade your libmysqlclient18 packet ? (Perform an apt-get update before, just in case ...)
I am using Fedora 14 and I have MySQL and MySQL server 5.1.42 installed and running.
Now I tried to do this as root user:
gem install mysql
But I get this error:
Building native extensions. This could take a while...
ERROR: Error installing mysql:
ERROR: Failed to build gem native extension.
/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /usr/lib/ruby/ruby.h
Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/mysql-2.8.1 for inspection.
Results logged to /usr/lib/ruby/gems/1.8/gems/mysql-2.8.1/ext/mysql_api/gem_make.out
What's wrong here? In installed ruby 1.8.7. and the latest rubygems 1.3.7.
For those who may be confused by the accepted answer, as I was, you also need to have the ruby headers installed [ruby-devel].
The article that saved my hide is here.
And this is the revised solution (note that I'm on Fedora 13):
yum -y install gcc mysql-devel ruby-devel rubygems
gem install -y mysql -- --with-mysql-config=/usr/bin/mysql_config
For Debian, and other distributions using Debian style packaging the ruby development headers are installed by:
sudo apt-get install ruby-dev
For Ubuntu the ruby development headers are installed by:
sudo apt-get install ruby-all-dev
If you are using a earlier version of ruby (such as 2.2), then you will need to run:
sudo apt-get install ruby2.2-dev
(where 2.2 is your desired Ruby version)
Red Hat, Fedora:
yum -y install gcc mysql-devel ruby-devel rubygems
gem install -y mysql -- --with-mysql-config=/usr/bin/mysql_config
Debian, Ubuntu:
apt-get install libmysqlclient-dev ruby-dev
gem install mysql
Arch Linux:
pacman -S libmariadbclient
gem install mysql
For anyone reading this in 2015: if you happened to install the package ruby2.0, you need to install the matching ruby2.0-dev to get the appropriate Ruby headers. The same goes for ruby2.1 and ruby2.2, etc. For example:
$ sudo apt-get install ruby2.2-dev
it seems that the
yum install ruby-devel
was enough for me to perform
gem install datamapper
afterwards.
It's possible that you will need to install another packages:
yum install gcc gcc-c++
to be able to build native extensions
MAC users may face this issue when xcode tools are not installed properly.
Below is the command to get rid of the issue.
xcode-select --install
I found the solution here.
# yum install mysql-devel gcc make
# gem install mysql -- --with-mysql-config=/usr/bin/mysql_config
This post helped me. Thanks a lot.
On Linux (Ubuntu 12.10) I needed to run
sudo apt-get install ruby
sudo apt-get install rubygems
sudo apt-get install ruby-dev
before I could succesfully run
sudo gem install jekyll
If you have gem installed and ruby and not able to install rails, then install ruby dev lib.
sudo apt-get install ruby-dev
It works for me. I have tried the different solution.
Red Hat, Fedora:
sudo dnf -y install gcc-c++ redhat-rpm-config ruby-devel gcc mysql-devel rubygems
For those that are still experiencing problems, like I have(I am using Ubuntu 16.04), I had to put in the following commands in order to get some gems like bcrypt, pg, and others installed. They are all similar to the ones above except for one.
sudo apt-get install ruby-dev -y
sudo apt-get install libpq-dev -y
sudo apt-get install libmysqlclient-dev
sudo apt-get install build-essential patch -y
This allowed me to install gems like, PG, bcrypt, and recaptcha.
My initial solution was to resolve the above errors by installing ruby-devel, patch and rubygems.
My issue was a bit different as bcrypt 3.1.11 still had issues compiling and installing on Fedora 23. I needed additional packages. So after ensuring I had the above installed, I was still having issues:
gcc: error: conftest.c: No such file or directory
gcc: error: /usr/lib/rpm/redhat/redhat-hardened-cc1: No such file or directory
From here I had to do the following:
I ensured that I wasn't lacking any C compiler tools sudo dnf group install "C Development Tools and Libraries"
Then I ran sudo dnf install redhat-rpm-config to resolve the gcc issue listed above.
You can find a write up here on Fedore Project. You may also find answers to other needs as well.
sudo apt-get install ruby-dev
This command solved the problem for me!
You need following packages instaled:
ruby-dev
gcc
libffi-dev
make
Here's the command for debian distro:
sudo apt install gcc ruby-dev rubygems libgmp-dev libgmp3-dev make
in openSUSE:
zypper in ruby-devel
Works to me :)
It's necessary to install redhat-rpm-config to. I guess it solve your problem!
This worked for me:
yum -y install gcc mysql-devel ruby-devel rubygems
You might have messed up with the RVM.
Try to do:
\curl -sSL https://get.rvm.io | bash -s stable --rails
Just to add path to ruby.h file in my PATH
for example:
export PATH=$PATH:/usr/src/ruby-xxxxxx
