"The automatic download of the update is currently not available" has been in the update-checker for years. Users know that it has been there for years. Users might think that there's no progress and might extrapolate it to the whole of LibreOffice. It's bad UX.
Suggestion: Remove the Autoupdate (non-)functionality completely, or give a vague timeline (i.e. "will be implemented in 2020").
Steps to Reproduce:
1. Open the update checker.
"The automatic download of the update is currently not available" appears.
A working auto-updater, an expected date when it will be implemented, or no mention of it at all.
User Profile Reset: No
UX-team, attention! Bad UX is here!
No, this is just running the cURL based 'check for updates' script to test currency of release, this check will autorun, but no direct action results.
At some point we may move to incremental updates probably MAR based--but thus far the prototyping has been just for Linux and Windows, no work yet (and I beleive that is part of the holdup) for macOS.
For the current 'Check for updates' the Install button is intentionally *disabled* for security reasons, while the Download button just links web browser to projects download site for a user controlled manual download, followed by manual nstallation.
