[slurm-users] Slurm does not start after (stupid) upgrade from 16.05.9 to 20.11.7

[Julien Tailleur]

Dear Ole,

thanks for your answer and your useful links. I finally managed to 
change the root password of mariadb and successfully ran

mariadb-upgrade

I could then restart everything and the cluster seems to be running 
again (!)

I will run more checks and will also ask questions on the debian-hpc 
mailing list, because all packages have changed names and I am a bit 
lost :-)

Best wishes,

Julien
