Although it sounds like gnome-shell crashed, truncated core files are not the fault of the program that crashed.
Please delete all core files in /tmp/ and /var/crash/ and then next time gnome-shell crashes, 1. Wait 10 seconds. 2. Reboot. 3. Run this command: journalctl -b-1 > prevboot.txt 4. Attach the resulting text file here. 5. Also follow these instructions to check for any new crash reports: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1939740 Title: Reporting a bug fails because of error message "Invalid core dump" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1939740/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
