SeaHub service doesn't start after Upgrade from Debian 10 to 11

When I upgrade my Debian 10 to 11, the SeaHub service does not start anymore. Has anyone encountered the same problem or is there a known solution here? Unfortunately, I cannot find any clues in the log files.

  • Seafile 10.0.1
  • Debian 10
  • Upgrade to Debian 11

Thanks,
Stev

try to enable “DEBUG = True” in seahub_settings.py

It was not a seafile problem.

  1. MariaDB Upgrade Bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1035949
5.1.6. MariaDB package names no longer include version numbers
Unlike bullseye that had the MariaDB version in package names (e.g. mariadb-server-10.5 and mariadb-client-10.5), in bookworm the equivalent MariaDB 10.11 package names are fully versionless (e.g. mariadb-server or mariadb-client). The MariaDB version is still visible in the package version metadata.
There is at least one known upgrade scenario (Bug #1035949) where the transition to versionless package names fails: running
apt-get install default-mysql-server
may fail when mariadb-client-10.5 and the file /usr/bin/mariadb-admin in it is removed before the MariaDB server SysV init service has issued a shutdown, which uses mariadb-admin. The workaround is to run

apt upgrade

before running

apt full-upgrade

I had to reinstall the dependencies after the “apt full-upgrade”

sudo apt-get update
sudo apt-get install -y python3 python3-setuptools python3-pip libmysqlclient-dev
sudo apt-get install -y memcached libmemcached-dev

# replace for libmysqlclient-dev
sudo apt-get install -y libmariadb-dev
