Do you have a sudo command? If not, can you perhaps install one and try again?

I was using a basic docker container to build for another platform and did not have a sudo command. You should really add a proper error message when none is found, and maybe skip the check when already running as root.

[Un1q32]

also you should add su as a fallback if theres nothing else, since basicly everything has su

I can't speak for the developer, but personally I'd like to see this reopened. At the very least, topgrade should produce a proper error instead of a panic.

True. I'll reopen.
