[Bug 2055147] Re: Kernel upgrade to 6.5.0-21-generic fails to boot
Hi Sly, We do actually test as many dkms builds as we can. Well, mainly all the kernel modules present in the Ubuntu archive, like evdi-dkms. The trouble starts when you get dkms sources from other places that we don't know about, like the DisplayLink installer that I linked above. You, me, and other users just install it, and forget all about it, until something breaks. The real solution is to get rid of as many out of tree kernel modules as we can. In the case of evdi, a few people have tried, and failed, to get it into the mainline kernel. Upstream aren't interested in tidying it up for inclusion, so it just rots out of tree. Anyway, I am glad that it works for you now.

[Bug 2055147] Re: Kernel upgrade to 6.5.0-21-generic fails to boot
Thanks. Installing an updated EVDI seems to have done the trick `sudo apt-get install evdi-dkms`. The new kernel is now working. However it is not good that automatic updating the kernel broke boot up. I know that there are so many different packages, etc, that you can't possible test all combinations. But maybe there is some way the install could test if the compile works, and if it doesn't then don't add/configure the new kernel but instead report an installation error. The problem would still need fixing, but at least it can be checked before installing that would stop creating a boot up issue. Or maybe you have to install the kernel first before it can be checked, so that may not be possible. Anyway, thanks for the help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2055147 Title: Kernel upgrade to 6.5.0-21-generic fails to boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2055147/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2055147] Re: Kernel upgrade to 6.5.0-21-generic fails to boot
Hi Sly, Your evdi kernel module for DisplayLink docks failed to compile. It likely couldn't generate your initramfs, leaving your 6.5.0-21-generic not able to boot. Your logs say its trying to build version 1.11.0: ERROR (dkms apport): binary package for evdi: 1.11.0 not found Error! Bad return status for module build on kernel: 6.5.0-21-generic (x86_64) Consult /var/lib/dkms/evdi/1.11.0/build/make.log for more information. This is a bit old and outdated. You can re-install the DisplayLink drivers from the upstream source, that has a newer version of evdi: https://www.synaptics.com/products/displaylink-graphics/downloads/ubuntu That will probably remove the old evdi and install a newer one. Alternatively, you can remove the old evdi dkms entry and install evdi- dkms from the Ubuntu repositories which has a evdi compatible with 6.5.0-21-generic. DisplayLink support is kinda bad on Ubuntu, but its what we must do to have working displays with our docks.
