I can guix install emacs and get emacs 29.1
I can guix install emacs@29.1 and get emacs 29.1
However, I can't get any other version of emacs, I need to stay on emacs 28.2 but... guix install emacs@28.2 returns package version not found for 28.2 (same story for 28.1 and 27.1 which are both tagged releases).
What am I doing wrong? Searches isn't turning out an obvious issue, I would appreciate any pointers!
