MySQL coud not be started, please check if the MySQL server is installed properly
If You don’t find the answer, ask in CQRLOG forum and attach last 20 lines from the mysql.erre.file

install the following package:
sudo apt install mariadb-server-10.3 mariadb-client-10.3
And it already works.

Hello,

Hello,
I just installed Ubuntu 20.04 then CQRLOG.
I am having problems launching CQRLOG, which led me to consult the forum and I came across this discussion, and I hastened to apply the suggested command.

I still encounter the same error:
Error during connection to database: TMySQL57connection Server connect failed.
On the "Database problem" window I cannot open the "mysql.err file" file
By performing a search on my / home I find an empty file.

Thank you for helping me solve this problem,

cordially

Make sure you're not still

Make sure you're not still running MySQL alongside MariaDB.
