This might also arise due to the different dependencies of linux-image- generic linux-image-virtual-hwe-22.04.
diff <(apt-cache show --no-all-versions linux-image-generic | grep -F Depends) <(apt-cache show --no-all-versions linux-image-virtual-hwe-22.04 | grep -F Depends) 1c1 < Depends: linux-image-5.15.0-139-generic, linux-modules-extra-5.15.0-139-generic, linux-firmware, intel-microcode, amd64-microcode --- > Depends: linux-image-6.8.0-59-generic So, on system having _only_ linux-image-generic installed the dependency is full-filled and the incorrect dependencies in both zram-config and zram-tools go unnoticed. On systems using the HWE kernel the missing dependency leads to a failure. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2034699 Title: zram-config has a missing dependency on linux-modules-extra-xxxx- generic Status in linux package in Ubuntu: Confirmed Bug description: I am running a virtual sever at Hetzner who provides a very slim preconfigured installation. zram-config was not installed so I ran ``` apt install zram-config ``` which installed it without any dependencies. after I started the service with ``` systemctl start zram-config.service ``` I got the following error message in journal: ``` Sep 07 10:53:00 Valheim-Server systemd[1]: Starting Initializes zram swaping... Sep 07 10:53:00 Valheim-Server init-zram-swapping[747]: modprobe: FATAL: Module zram not found in directory /lib/modules/5.15.0-83-generic Sep 07 10:53:00 Valheim-Server init-zram-swapping[745]: /usr/bin/init-zram-swapping: 10: cannot create /sys/block/zram0/disksize: Directory nonexistent Sep 07 10:53:00 Valheim-Server init-zram-swapping[756]: mkswap: cannot open /dev/zram0: No such file or directory Sep 07 10:53:00 Valheim-Server init-zram-swapping[758]: swapon: cannot open /dev/zram0: No such file or directory ``` I tried to locate zram.ko, but it was missing, so I tried to find out with ``` dkpg -S zram.ko ``` which package contained it: linux-modules-extra-5.15.0-83-generic After I manually installed that specific package, zram started working with ``` systemctl restart zram-config.service ``` I know, this might be a corner-case, but I found at least two other posts with the same problem in a very short time. Now my question. Would it be possible to add linux-modules-extra-xxxx- generic as a dependency zo zram-config, since it is not useable without it?
