I have tested the proposed package on Lunar/Jammy/Focal Tested packages: Lunar: 0.8.8-1ubuntu2 Jammy: 0.8.8-1ubuntu1.22.04.2 Focal: 0.8.3-1ubuntu2.2 Just going to write the results down for Lunar, because they are almost identical; the only difference is you don't need to pin proposed for Jammy/Focal. That's just there because in Lunar proposed pocket is pinned below main (You can also use `apt -t lunar-proposed install multipath-tools` to install). Steps: 1. Create VM in Linode - I used Nanode 1GB as my Plan 2. Wait for VM to boot 3. Stop VM 4. Change to paravirtual Kernel In linode dashboard * go to Configurations -> Edit -> Select a Kernel -> 6.0.2-x86_64-linode157 Save Changes 5. Power On Linode 6. Update packages # apt update -y 7. Reproduce failure, we can do this by uninstalling the package and reinstalling # apt remove -y multipath-tools # apt install -y multipath-tools Reading package lists...
