Couple of things

[BrokenGabe]

In regards to the .bashrc file provided, at line 123 you have the following alias, however in ArchLinux and as far as I am aware, debian both use /bin/bash/rm. /bin/bash/trash doesn't exist unless manually installed.

alias rm='trash -v'

Secondly, not sure about Debian, but on ArchLinux fresh install, your setup-arch.sh script installs fine without error, but it requires that zoxide be installed manually. probably should have that installed in your setup-arch.sh script.

zoxide is installable through pacman.
