My WSL2 currently has a single distribution - Ubuntu 18.04. I wish to upgrade it in place to the latest and so I ran the steps described in https://www.nextofwindows.com/how-to-upgrade-existing-wsl-wsl2-ubuntu-18-04-to-20-04, namely:

sudo apt update
sudo apt list --upgradable
sudo apt upgrade
sudo apt --purge autoremove
sudo apt install update-manager-core
sudo do-release-upgrade

For the last step I had to follow the instructions in https://askubuntu.com/a/1296373/611551, namely to link /usr/lib/ssl/cert.pem to /etc/ssl/certs/ca-certificates.crt, but it finally runs, only it fails short afterwards:

And it hangs. At this point I have no choice but aborting it. Retrying does not help.

What am I doing wrong?

  • I do keep an eye out for WSL questions here on Ask Ubuntu, but I usually look for the [tag:windows-subsystem-for-linux] tag. Did you resolve the issue (and if so, suggest posting an answer). If not, I've added an answer below - I thought there was a duplicate for this, but I can't find it now. – NotTheDr01ds Nov 28 '22 at 02:41

In my experience, this is often caused in older release upgrades by the presence of the snapd package and the lack of Systemd support in WSL. Before running sudo do-release-upgrade, try:

sudo apt remove snapd

Hopefully the upgrade will proceed as expected.
