I can confirm this on 22.04 LTS. Affects both Ubuntu and Xubuntu images. It is impossible to install from a DVD.
Three different computers, three different (verified both media and drive) DVD-R's, three different drives, all behave similar: - The splash screen after selecting "Try or install Ubuntu" just takes forever and then throws "Failed to start Ubuntu Live CD installer". Meanwhile the DVD shoeshining goes on. - Removing the "quiet splash" from the grub menu indicated that the services are timeoutting (f.ex. Snap Daemon and Network Manager) - Adding the "fsck.mode=skip" yielded a successful install on all three computers. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1930880 Title: Booting Ubuntu 21.04 from DVD takes more than 30 minutes and its environment are corrupted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/1930880/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
