I’m starting with a new one: duplicati/duplicati:linux-amd64-2.0.4.1_experimental_2018-11-08
without attempting any updates to an existing container, if that’s what you’re doing. I also tried a new 2.0.3.4.
??? Does that mean these are two different containers? I consider the one listed at top as “official Duplicati”. Regardless, you’re seeing this oddity at least sometimes, and the unpredictability of results does bother me.
From a shell inside container, this tends to find onedrive (unlike web UI) but no v2:
# pwd
/opt/duplicati
# head -1 changelog.txt
