[qubes-users] Troubleshooting: KaliVM update error: Failed to return clean data

Documentation followed: https://github.com/Qubes-Community/Contents/blob/master/docs/os/pentesting/kali.md

Currently at step 9 (again). I ran the Qubes updater when prompted and got the below terminal text. I’m unsure how to interpret this terminal text or how to fix it on my own. I’m going to try to run the qubes updater again and see if that works. Any help on troubleshooting this would be appreciated. As an aside, sorry for the multiple posts for each issue; I keep running into something different each time. Thank you all for your patience.

TERMINAL TEXT BELOW

Updating kali-rolling

Error on updating kali-rolling: Command ‘[‘sudo’, ‘qubesctl’, ‘–skip-dom0’, ‘–targets=kali-rolling’, ‘–show-output’, ‘state.sls’, ‘update.qubes-vm’]’ returned non-zero exit status 20
kali-rolling:

Fixed by running apt-full-upgrade. I’m good to go.
