Im running ispconfig on a few RaPis running Debian 10 and they've been fine for years but im thinking its about time to upgrade. Ive attempted the autoinstall script on them and it fails due to the RAR package not being in the Arm repository. Running the failing command manually via the debug switch this is definitely the sticking point. Is there any way to get this to work on Arm? As the install script seems to be remote i assume there's no way to edit it and remove the requirement for the rar package? Is there a way of removing it or building it so the script proceeds? Failing that is there an up to date Bullseye/Arm manual guide? Ive attempted to install it via the Debian 10 and using the various upgrade howtos to change PHP versions and so on and it sort of installs but things like rspamd dont seem to work and other things. Or is it really a case of sticking to Deb 10 for the time being until things are sorted?
