I couldn't resist a challenge :), so I installed GCC version 5. In the process of trying to compile a bisected kernel, my file system somehow got corrupted. I have no idea who the culprit is, as this laptop is very old. So, it could be a hardware issue, who knows.
But this exercise has convinced me that these Toshiba laptops are just too outdated for modern Linux versions. I've reformatted my filesystems, and I'm falling back to 16.04 Mate. I'll stay there as long as the laptop lasts. Thanks all for attempting to help. As Kenny Rogers would say, you gotta know when to fold 'em. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776616 Title: Ubuntu 18.04 getting stuck at "Starting Reboot" and "Starting Power- Off" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1776616/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
