Description

man.profile breaks man, at least on Gentoo.

Steps to Reproduce

$ man man
'xterm': unknown terminal type.
/usr/bin/man: command exited with status 1: sed -e '/^[[:space:]]*$/{ N; /^[[:space:]]*\n[[:space:]]*$/D; }' | LESS=-ix8RmPm Manual page man(1) ?ltline %lt?L/%L.:byte %bB?s/%s..?e (END):?pB %pB\%.. (press h for help or q to quit)$PM Manual page man(1) ?ltline %lt?L/%L.:byte %bB?s/%s..?e (END):?pB %pB\%.. (press h for help or q to quit)$-R -M --shift 5 MAN_PN=man(1) manpager

Expected behavior

Manpage should open.

Actual behavior

Errors above.

Behavior without a profile

What changed calling LC_ALL=C firejail --noprofile /path/to/program in a
terminal?

Works correctly.

Additional context

Adding terminfo to the existing private-etc seems to do the trick.

Environment

Name/version/arch of the Linux kernel (uname -srm): Linux 6.6.119-gentoo x86_64
Name/version of the Linux distribution (e.g. "Ubuntu 20.04" or "Arch Linux"): Gentoo
Name/version of the relevant program(s)/package(s) (e.g. "firefox 134.0-1,
mesa 1:24.3.3-2"): man 2.13.1
Version of Firejail (firejail --version): firejail version 0.9.80
If you use a development version of firejail, also the commit from which it
was compiled (git rev-parse HEAD):

Checklist

I am using firejail 0.9.80 or later
I am using the full program path (e.g. firejail /usr/bin/vlc instead of firejail vlc; see https://github.com/netblue30/firejail/issues/2877)
The issues is caused by firejail (i.e. running the program by path (e.g. /usr/bin/vlc) "fixes" it).
I can reproduce the issue without custom modifications (e.g. globals.local).
The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
The profile (and redirect profile if exists) hasn't already been fixed upstream.
I have performed a short search for similar issues (to avoid opening a duplicate).
- I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
[n/a] I used --profile=PROFILENAME to set the right profile. (Only relevant for AppImages)
