A couple weeks ago, I posted a thread about intermittent issues I was having on Ubuntu 18.04. Since RC came out yesterday, I decide to upgrade to the Beta a few days before as I figured Beta issues were mostly ironed out by now.
On my Ubuntu 18.04 host I began the update process via CLI which download 2G or so and began to run. Near the end of the upgrade my screen went gray and was unresponsive. I waited in this state for approximately an hour, before forcibly rebooting the system. After the reboot, the system did not come, I would just get a gray screen after unlocking the disk.
So off to my other Ubuntu 18.04 laptop to create a 20.04 Live USB. I was able to unlock the drive and copy my files using Live OS. I only needed to grab a few things because I do everything on Office Online.
I grabbed
-
User configurations /home/user/.config (mainly for /home/user/chromium/default/Bookmarks)
-
Network and VPN connections (very convenient) /etc/NetworkManager/system-connections/
-
SSH keys /home/user/.ssh
-
Some other things here or there
Clean install went great. I wiped the disk and most of the little nagging issues I had are gone. I have had wireless die on my twice in 4 days. This was fixed my restarting network-manager
Ubuntu 20.04 seems to be an awesome OS. I wish the upgrade would have worked, but I really needed a clean install anyway.
