When trying to upgrade 20.04 to 20.10 using update-manager button Upgrade, I get a message that I must first install all updates. I did sudo apt update + upgrade and I installed all updates suggested by update manager. Now I get no message in the terminal, but nothing happens when I click the button Upgrade or use the command sudo apt -y update && apt -y dist-upgrade. Fyi: I have a triple boot system with Windows 10/Ubuntu LTS 20.04.1 and Ubuntu development version (currently 20.04.1) on tree different partitions (2 hard disks).

You're on an LTS (long time support) version. There is some safety built in the system that you don't inadvertently upgrade to a non-LTS version.

To overrule this, just for this upgrade, do:

sudo nano /etc/update-manager/release-upgrades

and change Prompt=lts to Prompt=normal.

Then do sudo do-release-upgrade and your upgrade should proceed normally.

This may help.

I had two packages (related to tor) failing install due to an unmet dependancy. (found using sudo apt list --upgradable)

So I removed tor and did the upgrade:

sudo apt remove tor

sudo do-release-upgrade

And then proceeded with the install.

I would reinstall tor after the upgrade.

The lack of error messages was frustrating.

I'm sure it's logged somewhere.
