>Try to force reboot/power down earlier during the boot Not possible.
This is the boot process: 1. push power button 2. type in decryption password 3. hit enter 4. you immediately receive the Ubuntu splash screen 5. more and more (but not all) red dots appear 6. system hangs at 3 or 4 red dots It is not possible to act between steps 3 and 4. >see also https://wiki.ubuntu.com/RecoveryMode I have a fully duplicate backup test machine that manually mirrors my main machine. After the very first boot failure, I ported ALL the backup data to the test machine from which all these notes are coming. To reproduce all of the prior stated issues, I had to reinstall a new 19.04 from USB key. There is nothing to recover, for me at least. You are welcome to propose various tests on the failed machine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1831514 Title: Ubuntu 19.04 system update causes boot failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1831514/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
