Indeed, the lack of man pages support in snaps can be quite annoying. Unfortunately, individual snaps can do nothing about it, as it needs to be supported by snapd (here's the bug report). The good news is that a fix has been discussed and designed at the snapcraft forum. Edit: there's actually an old PR under review, but it's blocked :-(.

Will leave this issue open as a reminder to add a proper man page whenever the feature lands in snapd.

Thanks for your report!

Maxiberta, I don't quite agree with your sentiment.

You could put the manpages inside the snap in /snap/htop/current/share/man A user can then do the following in .bashrc (or another file): export MANPATH=":/snap/htop/current/share/man"

And then the manpages work. But since you didn't even include the manpages inside the snap, this workaround does not work. The workaround works on other snaps, like nano, tmux etc.

@ameinild fyi, the man page is included in the snap: /snap/htop/current/usr/local/share/man/man1/htop.1.

Ok thanks for clearing that up.
