Dear Maintainer,

I am not able to run man anymore:

- enter: man ls

Expected:

- man page is shown

Actual behavior:

Error clone: main.c:2453 main: Operation not permitted

Sorry for the delay in getting back to you.  Please could you run "sudo
strace -f -o man.trace -s 1024 man ls", and attach the resulting
man.trace file in an email to me?

Dear all,

I also have this problem in sid. As a user I get this error:

As root it works. I created the strace file as root as you suggested to use sudo (I don't use sudo myself on this machine).

Best regards,
Martin

Hey,

I actually got the same issue on my machine after having updated to
bullseye/testing. Man pages were only viewable as root. I noticed that
this behaviour originates from firejail which happened to wrap "less"
through a symlink "/usr/local/bin/less" to "/usr/bin/firejail", which
was once installed by firecfg. However, there was no such link for man
itself.

I could solve the issue by either starting man in firejail right away
(`firejail man ls`), or by removing the link for less in
"/usr/local/bin/less".

Best

Maximilian
