yup it seems like it was a network error. I also couldn’t get aur packages installed using pacmanity for some reason this didn’t work
paru-S $(sed -e '/^$/d' Garuda-Linux.pacmanity | tr '\n' ' ')
I had to get each package name and do a paru -s packagename which was a little annoying
strangely pacman worked fine with the above just not paru I guess you can’t read from a file and pass that to paru?
Anyway
as for flatpaks I just did ls /mnt/broken/@/var/lib/flatpak/app/ to get all flatpaks installed system wide (transferring my home already copied my users flatpaks)
So got everything in place
