I'm STILL having trouble connecting to
http://devuanfwojg73k6r.onion/merged . Other onion sites seem to be
okay. Is that site working?

On my Debian machines, http://vwakviie2ienjx6t.onion/debian is still
working just fine.

My /etc/apt/sources.list.d/devuan.sources:

Types: deb deb-src
URIs: tor+http://devuanfwojg73k6r.onion/merged
Suites: ascii ascii-updates ascii-security
