issue with using system packages

[da5nsy]

Following #5

i Getting 1 pkg with unknown size, 69 (53.37 MB) cached
v Cached copy of CarpentriesSlides 0.0.0.9000 (source) is the latest build
i Installing system requirements
i Executing `sh -c apt-get -y update`
Error: 
! error in pak subprocess
Caused by error in `processx::run(sh, cmdline, stdout_callback = callback, stderr_to_stdout = TRUE)`:
! System command 'sh' failed

Any advice?

(At this stage I'm giving up on trying to use R inside apptainer, for now at least, but logging this here in case others encounter this issue)
