Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to review all reported bugs in a timely manner.
'crash' is a kernel debugging utility which the bug description shows that you do not have installed. It is not a package against which you should report crashes. https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment might be of help here but crashes should always be reported against the offending package. The contents of the /var/crash directory might give an indication as to which application has crashed and against which a bug report should be raised. Ubuntu 18.04 (bionic) reached end-of-standard-support on May 31, 2023 so closing as 'Invalid'. ** Package changed: crash (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772178 Title: system crashes when exiting from console 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1772178/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
