Can't upgrade to Ubuntu 21.04 : "Restoring original system state. Aborting"

us flag

I am trying to install Kubuntu 21.04 but I get this error that never happened before :

Restoring original system state

Aborting
Reading package lists... Done    
Building dependency tree          
Reading state information... Done

I tried to disable all the PPA, without success.

Here is the /var/log/dist-upgrade/main.log output :

`systemct status snapd.service` Is it running?

To be honest, I've checked another thread that suggested to do `sudo apt-get purge snapd` and it worked !

Removing snapd with sudo apt-get purge snapd was the solution.

This also works when using WSL2 and ubuntu imported as rootfs!

Worked for me. This was blocking me from upgrading my WSL distro from Ubuntu 18.04 to 20.04

Was also affected by this. After removing snapd it still affected me. The last comment on this thread pointed the fix that worked for me https://github.com/microsoft/WSL/discussions/3489#discussioncomment-961901

I had to remove both snapd and screen!

1 - sudo apt-get purge snapd

2 - sudo apt-get purge screen

And then the upgrade ran smoothly. If it is still failing, you can cat /var/log/dist-upgrade/main.log to see what's causing you to fail!

ftw @ wsl2, thx

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
