Installing MySQL 5.6 in newer releases of Ubuntu (like 20.04)

One might face difficulties in setting up MySQL 5.6 in the newer releases of Ubuntu (like 18.04 or 20.04). Nothing to worry. Here is a step-by-step guide for doing that.

• Download the MySQL Community Server DEB Bundle from here.

  • Select 5.6.* as Product Version, Debian Linux as Operating System and then download the 32-bit or 64-bit DEB Bundle as per the system's requirement.

  • It basically contains individual packages like mysql-common, mysql-community-client, mysql-client, mysql-community-server, etc.

• Install the packages individually using dpkg -i <package-name>.deb

• Note that it will be required to go in a certain order for installing the packages, which could be found out by trial-and-error (see the error messages if any for the other package's requirement).

• In case there is some error for missing dependencies, run sudo apt-get install -f

An example case:

I use Ubuntu 20.04 and I went in the following order:

sudo dpkg -i mysql-common_5.6.47-1debian9_amd64.deb 
sudo dpkg -i mysql-community-client_5.6.47-1debian9_amd64.deb 
sudo dpkg -i mysql-client_5.6.47-1debian9_amd64.deb 
sudo dpkg -i mysql-community-server_5.6.47-1debian9_amd64.deb

After this, I got some errors (maybe because of the order I followed). I again did:

sudo dpkg -i mysql-common_5.6.47-1debian9_amd64.deb
sudo dpkg -i mysql-community-client_5.6.47-1debian9_amd64.deb

After this, I got some errors about missing dependencies, so I ran:

sudo apt-get install -f

That's it, MySQL 5.6 successfully got installed!

Kill the previous mvn clean install or mvn jetty: run every time you rerun maven. Otherwise, it might gives a following error indicating address already in use.
