Hi! I’ve used an installer built from this commit: --8<---------------cut here---------------start------------->8--- Generation 214 May 02 2022 21:44:14 (current) guix 6b588da repository URL: https://git.savannah.gnu.org/git/guix.git branch: master commit: 6b588da368c77cde82ea2f22ca315116228777ad --8<---------------cut here---------------end--------------->8--- During installation, ‘guix system init’ displays dots instead of progress bars for downloads and such. This suggests that ‘display-download-progress’ gets #:tty? #f. This may be a side effect of running it in a pipe in ‘run-external-command-with-handler’. Thoughts? Ludo’.
