Actually, I totally spaced this. I did verify it's working fine in Focal using the fix. I just forgot to mark verification done. ** Tags removed: removal-candidate verification-needed verification-needed-focal ** Tags added: verification-done verification-done-focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892949 Title: [SRU] grub can no longer detect kernels after ubuntustudio-lowlatency- settings is uninstalled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntustudio-default-settings/+bug/1892949/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I think I may have a spare machine that I can play with after I finish setting up a new one later today. I could do the test on this machine, but I really need it operational! Hopefully I will report back in the next day or so. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892949 Title: [SRU] grub can no longer detect kernels after ubuntustudio-lowlatency- settings is uninstalled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntustudio-default-settings/+bug/1892949/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Any luck in verifying this?

** Description changed: - ubuntustudio-lowlatency-settings does not contain a postrm script to - reenable executability (+x bit) of /etc/grub.d/10_linux after it has - been removed, thus rendering grub unable to detect any installed - kernels, potentialy breaking installations. + [Impact] + + * When ubuntustudio-lowlatency-settings is installed, it disables the executable +bit on /etc/grub.d/10_linux because it installs a replacement file at +/etc/grub.d/09_lowlatency in order to ensure that the lowlatency kernel is +always default when both generic and lowlatency are installed. + + * ubuntustudio-lowlatency-settings does not contain a postrm script to reenable +executability (+x) of /etc/grub.d/10_linux after it has been removed, thus +rendering grub unable to detect any installed kernels, potentialy breaking +installations and causing people's systems unable to boot. + + [Test Case] + + * Install Ubuntu Studio or add ubuntustudio-lowlatency-settings to any +installation + + * Uninstall ubuntustudio-lowalatency-settings, run update-grub. + + * Reboot. Kernels will be unavailable for boot. This is further proven prior to +this when update-grub is run as it will not detect any installed kernels. + + [Regression Potential] + + * The only regression this may have is that the .postrm script does not actually +add +x, but this is highly unlikely as it adds it if the /etc/grub.d/10_linux +file simply exists, even if the executable bit is already set. + + [Other Information] + + * This was recently discovered when I installed the surface-linux kernel on my +MS Surface Pro 4 and found it unable to boot the custom kernel, as with +ubuntustudio-lowlatency-settings it was only recognizing the generic and +lowlatency kernels. Removing ubuntustudio-lowlatency-settings and attempting +to run update-grub resulted in no kernels detected. Upon investigation, +I discovered that the +x bit was not set in /etc/grub.d/10_linux. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892949 Title: [SRU] grub can no longer detect kernels after ubuntustudio-lowlatency- settings is uninstalled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntustudio-default-settings/+bug/1892949/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
