nit: shellcheck:  https://www.shellcheck.net/wiki/SC2162 -- read without

here the '< /etc/apt/auth.conf' is missing (present in the pmg-api patch)

s/pmg.conf/pve.conf for this one

this leaves an emtpy /etc/apt/auth.conf (tested on a pmg-install) if the
only auth.conf entry was the one for our hosts
(maybe `test -n "$output" && echo "$output" > /etc/apt/auth.conf`
also maybe printf might save you the trailing newline)
