When using WSL2 on Win 10 Professional (build 2004 (20236.1000) in Ubuntu 18.04

I am running into the following error: see below picture. Googling does not lead to an answer to find the root cause and the fix for this problem. Hopefully, someone else has encountered and fixed this problem (again this happens in Ubuntu18.04 in WSL2 Thanks

Answer 1

This invoke-rc.d: could not determine current runlevel seems to be a very common issue with WSL: I've too encountered it as I was trying to set up the xfce4-desktop based on this guide.

I've found this related thread on github, maybe you'll find a solution there.

Answer 2

I just had the same issue with Ubuntu 20.04 in WSL just now for me it was just that the dbus folder was simply missing, based on your logs this could be the same issue create the dbus folder with:

sudo mkdir /var/run/dbus

Test dbus with:

sudo dbus-daemon --config-file=/usr/share/dbus-1/system.conf --print-address

rerun your command
