FYI: brew's mono breaks the 11-28 beta


See: Duplicati does not start up · Issue #3572 · duplicati/duplicati · GitHub

If you already have upgraded, you can probably downgrade as follows:

$ brew uninstall mono
Uninstalling /usr/local/Cellar/mono/ (3,810 files, 415.3MB)
mono is still installed.
$ brew link mono
Linking /usr/local/Cellar/mono/ 234 symlinks created "Unable to start up, perhaps another process is already running?" server appears to be broken on Synology beta says: warnings, but no warnings (or errors) available in log

Thanks for that! @kenkendk, in case you didn’t see it yet, there is a “What Mono framework is Duplicati built against” question at the GitHub link above.
