I also tripped over this on a fresh 16.10 install. It should certainly be fixed (as well as https://bugzilla.redhat.com/show_bug.cgi?id=569116 , frankly), but as a workaround, manually installing duplicity (e.g. sudo apt-get install duplicity) works fine (no warnings about untrusted software) got past this symptom for me.
Fake-edit: It looks like the expected Debian/Ubuntu way of solving this is to install deja-dup-backend-gvfs (which in turn depends on duplicity), thus supplying the requisite functionality for backing up to ssh, cifs, etc. Additionally, I don't know if it should be considered an additional [Debian/Ubuntu-specific] bug that the Déjà Dup preferences UI does enable the buttons when duplicity is installed, even though the act of clicking the button is supposed to install deja-dup-backend-gvfs, but I thought I should point that out. (debian/patches/install-pygi.patch sets this to install deja-dup-backend-gvfs instead of duplicity, but leaves the 'installed' check to look for duplicity.) ** Bug watch added: Red Hat Bugzilla #569116 https://bugzilla.redhat.com/show_bug.cgi?id=569116 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to deja-dup in Ubuntu. https://bugs.launchpad.net/bugs/1638510 Title: deja-dup asks to install software not from a trusted source Status in deja-dup package in Ubuntu: Confirmed Bug description: deja-dup opens a dialog "The software is not from a trusted source.
