Package: ganeti-3.0 Version: 3.0.1-2 Severity: normal Hello,
I've just performed an upgrade of a ganeti cluster from buster+2.16 to bullseye+3.0 and hit a problem during the upgrade. The procedure that I used was to: 1. install ganeti 3.0 from buster-backports and upgrade the cluster 2. run OS upgrade from buster to bullseye (I had not removed ganeti 2.16) During the upgrade to bullseye, ganeti was upgraded from the 3.0 backports package to the same one from bullseye. At that point, dpkg stopped with an error. Running "apt -f install" to fix the situation did not clear things up. Running "apt purge ganeti-2.16 ganeti-haskell-2.16 ganeti-htools-2.16" was jammed on a conflict of configuration files with 3.0: # apt -f install Reading package lists...

That permitted the package to finish upgrading and the os upgrade to complete. Once the upgrade was completed, I was able to purge ganeti 2.16 (and I had to manually remove the diversion that was left behind) I'm guessing this happened because the ganeti 2.16 packages were still in place. But it was a situation quite difficult to work around of. I'm wondering if something can be done to avoid this situation. -- System Information: Debian Release: bookworm/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.10.0-8-amd64 (SMP w/4 CPU threads) Kernel taint flags: TAINT_CPU_OUT_OF_SPEC Locale: LANG=en_CA.UTF-8, LC_CTYPE=en_CA.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages ganeti-3.0 depends on: ii adduser 3.118 pn bridge-utils <none> ii debconf [debconf-2.0] 1.5.77 pn fping <none> ii iproute2 5.13.0-2 pn iputils-arping <none> ii libcap2-bin 1:2.44-1 ii lvm2 2.03.11-2.1 ii openssh-client 1:8.4p1-6 ii openssh-server 1:8.4p1-6 ii openssl 1.1.1l-1 ii python3 3.9.2-3 pn python3-bitarray <none> pn python3-openssl <none> ii python3-paramiko 2.7.2-1 ii python3-psutil 5.8.0-1 ii python3-pycurl 7.44.1-1 pn python3-pyinotify <none> ii python3-pyparsing 2.4.7-1 ii python3-simplejson 3.17.5-1 ii socat 1.7.4.1-3 ganeti-3.0 recommends no packages. ganeti-3.0 suggests no packages.
