The only available logs are already attached. I have resolved my specific issue by removing the offending package, but the bug that triggered the segfault still remains when reinstalled.

Hard lock Status in linux package in Ubuntu: Incomplete Bug description: Ubuntu-Studio 20.04.3 LTS on MacPro 5,1, dual W3520 From /proc/version: Linux version 5.11.0-27-lowlatency (buildd@lcy01-amd64-019) (gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0, GNU ld (GNU Binutils for Ubuntu) 2.34) #29~20.04.1-Ubuntu SMP PREEMPT Wed Aug 11 17:06:56 UTC 2021 # apt-cache policy shim-signed shim-signed: Installed: 1.40.7+15.4-0ubuntu9 Candidate: 1.40.7+15.4-0ubuntu9 Version table: *** 1.40.7+15.4-0ubuntu9 500 500 http://us.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages 100 /var/lib/dpkg/status 1.40.3+15+1533136590.3beb971-0ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu focal/main amd64 Packages >What you expected to happen Running `apt upgrade` would complete without issue. >What happened instead System hard lock, becomes completely unresponsive both from the local terminal and over established SSH. Eventually memory is exhausted and the machine reboots. Upon restart, running `apt upgrade` returns the error: "E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem." Running `dpkg --configure -a` attempts to complete installation of shim-signed, segfaults, requiring a cold boot. Only a fraction of the errors generated get written to the logs before the crash as the crash prevents a final flush to disk. From a remote machine I tailed several logs and triggered the crash again, then copied the results from the terminal and attached to report.
