Hi! I was able to reproduce this with:
apt install mariadb-plugin-gssapi-server mariadb-plugin-gssapi-client sed s/bullseye/bookworm/g -i /etc/apt/sources.list apt update apt-get upgrade Upgrade only updates mysql-common and mariadb-common: $ dpkg -l | grep -e mysql -e maria ii libdbd-mariadb-perl 1.21-3 ii libmariadb3:amd64 1:10.5.19-0+deb11u2 ii mariadb-client-10.5 1:10.5.19-0+deb11u2 ii mariadb-client-core-10.5 1:10.5.19-0+deb11u2 ii mariadb-common 1:10.11.2-1 ii mariadb-plugin-gssapi-client:amd64 1:10.5.19-0+deb11u2 ii mariadb-plugin-gssapi-server 1:10.5.19-0+deb11u2 iF mariadb-server-10.5 1:10.5.19-0+deb11u2 ii mariadb-server-core-10.5 1:10.5.19-0+deb11u2 ii mysql-common 5.8+1.1.0 I applied manually the debugging patch I have in https://salsa.debian.org/mariadb-team/mariadb-server/-/merge_requests/26 on /etc/init.d/mariadb and it resulted in: $ /etc/init.d/mariadb restart Stopping MariaDB database server: mariadbd.
