Public bug reported: When upgrading to 24.04 today, the process stalled when it got to os- prober checks for other installed OSes.
As far as I can determine, this was because the network connection was completely destroyed during upgrade leaving the machine without connectivity, and when os-prober runs it erroneously attempts to look inside NFS mounts. Since there is no connectivity, it will apparently stall forever on this while the kernel logs a lot of errors to syslog.
