Description

With system-installed gdb (from apt-get), I can use ctrl-L to clear the screen.
However, using bin/pwndbg from pwndbg_2024.08.29_amd64-portable.tar.xz I couldn't do that.

Steps to reproduce

Download and install 1.
Load it by typing bin/pwndbg /bin/cat.
Generate some output: disass main
Try to clear the screen with ctrl-L.

My setup

Gdb: 15.1
Python: 3.12.4 (main, Jun 6 2024, 18:26:44) [GCC 13.3.0]
Pwndbg: 2024.08.29
Capstone: 5.0.1280
Unicorn: 2.0.1

There is also .inputrc and .gdbinit but I don't think those files causing this problem
because with vanilla gdb, ctrl-L works.

Issue was fixed in #2531 #2532
But not released yet.

For workaround you can execute:

export TERMINFO_DIRS=/etc/terminfo:/lib/terminfo:/usr/share/terminfo:/run/current-system/sw/share/terminfo

I am going to close this issue for the time being as we have a workaround above. This being said, we should make a release shortly so that this is fixed in the released version (along with many many other fixes, improvements and new features).
