Hi all,

I am new to both Linux and CQRlog and am using Linux Mint 18.2 Cinnamon 64-bit.

I tried to install CQRlog from the Archive Manager butr when starting it I got two messages.
“Information… It looks like apparmor is running in yout system. CQRlog needs to add this: ...”
“Error during connection to database. Can not load default MySQL library ...”

I was advised to remove apparmor and did so by
#sudo apt-get remove apparmor

However I still got the same messages so I uninstalled CQRlog throug the Archive Manager rebooted and installed the program again with the same result.

I then red the instructions here and used instructions for installing on Ubuntu
sudo add-apt-repository ppa:ok2cqr/ppa;sudo apt-get update;sudo apt-get install cqrlog

The installation worked nicely but when starting CQRlog I got the new messages
“MySQL could not be started, please check if the MySQL server is installed properly….
If you don’t find th eanswer, ask in CQRLOG forum and attach the last 20 lines from mysql.err file”
“Error during connection to database: TmySQLConnection: Connection failed”

The last 20 lines are attached below.
What do you suggest me to do?
