Upgrading to Ubuntu 20.04

eco_bach · 06-07-2020, 06:33 PM

Hi
I am or was on Ubuntu 18.04 LTS. Saw a prompt for a large upgrade thru Software & Updates so I clicked ok and let it run

After booting I saw the grub screen as normal then just a black screen
Was able to launch a terminal and ran sudo apt-get update etc and after some tweaks was able to get sort of a desktop environment(see attached)

However obviously not what I need. Screen resolution is wrong, not getting proper mouse tracking, etc.
Checking in terminal I confirm that I am now on 20.04LTS.
I also downloaded the Ubuntu MATE .iso file

How do I properly upgrade my MATE skin to 20.04?

In hindsight I should have followed these directions

Any feedback appreciated.

provided things work as you would expect with a live usb of 20.04, it seems like a re-install would be quicker and probably give you more confidence in your system overall than trying to troubleshoot your way out of an unfortunately messy upgrade.

I just did a Debian dist-upgrade and I recommend the process.
I believe it is essentially the same on Ubuntu, but I wouldn't trust those GUI utilities.
Maybe your upgrade didn't fully complete?
You could open a terminal and run the following:

Code:

apt update
apt upgrade
dpkg --configure -a
apt install -f
apt full-upgrade
apt dist-upgrade

I believe the order in which these commands are issued matters, and I'm not sure I got the order right there, so you might need to repeat this several times.
