Your system is unable to reach the snap store

This microsoft WSL issue completely made it work for me. Essentially it boiled down to:

1. Abort the do-release-upgrade script
2. Re-launch Ubuntu

3. Remove lxd with: sudo dpkg --force depends -P lxd; sudo dpkg --force depends -P lxd-client

4. Finish with sudo apt upgrade

I was faced with the same problem and found this question.

So far, the only answer requires to abort the do-release-upgrade script. I do not want this.

Here is the solution:

When the error message from lxd appeared, you are given three choices, one of them is skip.

After choosing skip, the following message appeared:

Skipping is not allowed when LXD has been initialized                                                                                                                  
LXD appears to have been configured on this system.
Please stop LXD and remove local data in /var/lib/lxd/ if  
you would like to skip installing the LXD snap and migrating the local data.                                    
                                     <Ok>

So FIRST, I opened another Ubuntu shell window and entered: sudo /etc/init.d/lxd stop The response was Stopping Container hypervisor based on LXC: (not running).

Then SECOND, I deleted the directory given in the message: sudo rm -rf /var/lib/lxd

LAST, I returned to the first Ubuntu shell window and pressed return. And chose skipagain. This time the installation continued.
