@mrpk1906 Can you also add a bugfix changelog fragment?

For convenience, there's a link to changelog doc https://docs.ansible.com/ansible/latest/community/development_process.html#creating-a-changelog-fragment

Hi @markuman @Andersson007
I updated changelogs

Please check :)

[Andersson007]

In terms of changelog LGTM.
If this role didn't work with python-mysqldb and after this PR gets merged it will work, LGTM

hmmm, maybe it works on focal (ubuntu 20.04) with that.

And maybe it breaks xenial (ubuntu 16.04)?
Imo xenial is EOL since April 2021.

I'll try to verify next days.

Tested with bionic and focal ... the role runs in other errors that are not related to that PR.
I'll open a separat issue for it.

@mrpk1906 Thanks for your contribution.
