You're not the only one having this problem, see bug 1958260. But it's unclear how one ends up in this situation without having removed modules manually. I'm not saying that's what happened here, I just don't see how this could happen 'automatically'. Basically what's happening is that copymods detects that there are no modules available for the running kernel, so it mounts a tmpfs to /lib/modules and copies all modules from the initrd. That's why you only see a subset of modules under /lib/modules. If then a linux-modules package is installed later on, the modules are written to the tmpfs which gets thrown away on reboot. To revover: Reboot into the original kernel: $ sudo flash-kernel --force 5.13.0-1008-raspi $ sudo reboot Verify that copymods is *not* active: $ grep copymods /proc/mounts Reinstall all modules packages: $ dpkg -l | awk '{print $2}' | grep linux-modules | xargs sudo apt get install --reinstall Reboot into the latest kernel: $ sudo flash-kernel $ sudo reboot Verify that copymods is *not* active: $ grep copymods /proc/mounts ** This bug has been marked a duplicate of bug 1958260 cloud-initramfs-copymods hides the full list of modules from the system -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1962053 Title: Modules missing from package install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1962053/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
