We want to add the official #Tor onion service for f-droid.org as an official mirror, so that clients will automatically use it. Please test by sharing the repo link to #FDroid client then add it as a mirror:
https://gitlab.com/fdroid/admin/-/issues/12#note_1184095205

This should prompt to add it as a mirror, which is safe since the keys need to match. Click cancel if it offers to add a new repo.
