I see where this is an issue with Ubuntu 16.4, however, it may be an issue also with Raspbian (debian) 'Jessie'.

(Note: I've had no problem running CQRLOG 2.0.1 (001) in Linux Mint 17.2.)

--

After installing CQRLOG 1.8.2 from the default repository on my raspberry pi 2B (Raspbian 'Jessie'), I started the program and got a 'Cannot connect to server' error when trying to create a new log. From reading the posts on this forum, I found out that the 'libmysqlclient-dev' package needed to be installed. I did that, and I still got the 'Cannot connect to server' error.

After deleting the ~/.configure/cqrlog folder, I unsuccessfully trying get past the new log creation, I decided that the problem was with the 'root password' in mysql. After removing the 'root password, I tried again and had the same result. I then decided to give 'pi' (default user) mysql administrator's rights. After doing that and removing the ~/.configure/cqrlog folder, I tried again and had the same result.

Below is what I got when starting cqrlog with debug in a root terminal session (note that I did 'x out' of cqrlog after the error):

(I am going to try to update from 1.8.2 to 2.0.1, if I can find an updated debian version.)
