Comment 2 for bug 2026179

Yep, me too.

System is Dell Precision 5570, trying to install Ubuntu 23.04 via iso on USB. I booted with safe mode graphics. (The try or install option appears to hang for at least 30 minutes.)

syslog (attached) has python segfaults (excerpt below). It appears that subiquity is immediately retrying after the segfault. Notice the restart counter at 110.
