I can confirm this bug. My VPS servers are configured to automatically reboot daily and one of them started hanging up with similar error a few days ago. I am using Ubuntu 18.10 x64 running on Vultr VPS. When the VPS hanged today, the screen ended with these messages:
[ OK ] Reached target Shutdown. [ OK ] Reached target Final Step. Starting Reboot... [ (several blank lines here) /shutdown: error while loading shared libraries: libidn.so.11: cannot open shared object file: No such file or directory The name of the library changes randomly with every hangup. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1822118 Title: Kernel Panic while rebooting cloud instance To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1822118/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
