Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run: ubuntu-bug YOURFILE.crash Then tell us the ID of the newly-created bug. 2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us. 3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1. Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself. ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1827953 Title: when you have "world clocks" configured (e.g. from the Gnome Clocks application), Gnome Shell crashes on login, resulting in a login loop Status in gnome-shell package in Ubuntu: Incomplete Bug description: Configure some “world clocks” in Gnome Clocks (or maybe using some other tool). Expected behaviour (how it worked in cosmic & before): Gnome Shell shows the time for the cities you configured when you click on the date at the top centre. What happens: Gnome Shell crashes just after login, creating a “login loop” where the user is locked out of their computer.
