I’m a black sheep, I install Soapbox using pleroma_ctl frontend install soapbox. And when I try adding --ref main it just downloads the latest develop branch release.
$ pleroma_ctl frontend install soapbox --ref main Installing frontend soapbox... 18:34:13.773 [info] Downloading pre-built bundle for soapbox 18:34:17.018 [info] Installing soapbox (develop) to /srv/www/static/frontends/soapbox/develop Frontend soapbox installed 18:34:20.679 [info] Frontend soapbox (develop) installed to /srv/www/static/frontends/soapbox/develop
