[ERROR] Moving LOG from one computer to another

Hi everyone,

Recently I had to switch computers and moved the folder ~/.config/cqrlog from the old computer to the new one. However, when I launch CQRLOG, I get the error shown down below...
Unfortunately, I don't have any backup of my LOGs.
My system is Debian Buster with CQRLOG 2.5.2 (001)

"Error during connection to database: TMySQL57Connection : Server connect failed."

Then, opening as suggested, the file mysql.err, the last lines (earlierlines are from dates previous to installation) show:

Does the new computer have same cqrlog version as the previous one?:
Or are you jumping from old cqrlog, possibly using old mysql, to new cqrlog using MariaDB? In that case there may be problem.

Did you try to start cqrlog before you moved the folder ? Did cqrlog start normally?
If you did not test that before copying the folder do rename your folder:
mv ~/.config/cqrlog ~/.config/cqrlog_moved

Then start cqrlog and check that it starts and creates a new log ok. If you have problems with that cqrlog does not work with moved folder either.
Once this check passes close cqrlog and delete current folder and rename the moved one back.
rm -rf ~/.config/cqrlog
mv ~/.config/cqrlog_moved ~/.config/cqrlog

Did you check that ownership of folder ~/.config/cqrlog is OK?
Open console and issue a command:
sudo chown -R emmanuel.emmanuel /home/emmanuel/.config/cqrlog

That should not make any harm if ownership is already in order.

If you managed to start cqrlog from "empty table" when moved folder was renamed it seems that there are differences in in database structure.
You should somehow get back to previous cqrlog version, do a full backup of qsos and log settings and then import them to this new PC's cqrlog.

Yes, I know... It might be impossible action.
But let's see first what these tests above do result.


Hi Saku,

Hi Saku,
Thank you for your time.

- The previous version of CQRLOG is 2.5.1.
- Yes, I did start CQRLOG before I moved the folder. Everything started normally. I did again now and everything works fine, until I replace the new folder with the old one.
- Ownership of the folder is OK.

Now the odd thing is that I removed version 2.5.2 and installed version 2.5.1 and the errors are absolutely the same. :(
I guess I'll have to download my log from the Web, import it to CQRLOG and reinsert by hand last QSOs into database...

Anyway, thank for your help.

2.5.1 and 2.5.2 both have MariaDB in dependencies so it shoud not be the problem that exists when jumping from Mysql to MariDB.
Now there is something else.
Please check that you have all MariaDB packages installed with this new PC:
mariadb-client-10.3 mariadb-server-10.3 libmariadb3 libmariadb-dev-compat
