Comment 9 for bug 1930880

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.
