After installing Ubuntu 22.04 on my PC, I installed CQRLOG using the following commands:
sudo add-apt-repository ppa:ok2cqr/ppa;sudo apt-get update;sudo apt-get install cqrlog
When I run cqrlog I get the error: Mysql could not be started
Below is the mysql.err file

As indicated in a topic I deleted the /home/daniel/.config/cqrlog file but that did not change the result.
Thanks for giving me a solution,
