LibreOffice binaries/installers are PGP-signed (good) but detached signatures aren't found on download page (not that good). One must do some detective work to find them. Suggestion: please include link to corresponding .asc file on download page.
Created attachment 179782 [details] LO download website 2022-04-26 Confirmed, looking at the download page, there is no trace of the signature file, which should be available. Attaching screenshot of current website design of download page. sha checksums (why are MD5 and sha1 even provided?) as well as OpenPGP signature are currently hidden behind the opaque "Info" link.
I thought I had looked at the info link but it's all there. I regret creating the bug. Changing to RESOLVED/NOTABUG. Apologies for noise.
