I am on WSL2 and had/have Ubuntu 18.04 installed. I went through a couple of steps to upgrade versions (enabling systemd, creating a symbolic link for apt-pkg, etc.). I was finally able to run sudo do-release-upgrade successfully and cat /etc/lsb-release returns DISTRIB_DESCRIPTION="Ubuntu 22.04.1 LTS".
However, my terminal and VS Code are still showing version 18.04. How do I fix this so I'm only using 22.04.1?
I was following instructions here and running these commands or variations of them:
$ sudo apt update$ sudo apt upgrade -y> wsl --shutdown$ sudo apt --purge autoremove$ sudo apt install update-manager-core -y$ sudo do-release-upgrade
I also ran the following command from here when I wasn't able to run reboot (before realizing I should just use wsl --shutdown in Powershell):cd /mnt/c/ && cmd.exe /c start "rebooting WSL" cmd /c "timeout 5 && wsl -d $WSL_DISTRO_NAME" && wsl.exe --terminate $WSL_DISTRO_NAME
I was getting an error saying "No module found named 'apt-pkg'", so I followed instructions here. That then gave me command not found error for do-release-upgrade, but I fixed that with this info.
I finally fixed the apt-pkg error by creating a symbolic link as described here so Ubuntu was directed towards python 3.6 instead of a more recent version.
I was then getting this error message when trying to run sudo do-release-upgrade:

I was then finally able to run sudo do-upgrade-release, but at the very end it prompts to reboot, so I wasn't able to do that in the same session and ended up just restarting my computer, hoping that would do the trick. It didn't (seem to at least)--I was still seeing Ubuntu 18.04. I hadn't run cat /etc/lsb-release yet, so I don't know if it had updated there or not. Because I was still seeing 18.04 in the terminal and VSCode, I basically just started running variations of apt update/upgrade and do-release-upgrade, so it's quite possible I upgraded twice without realizing it.
Please let me know if any other info is needed.
