Package: duplicity Version: 0.7.16-1 Followup-For: Bug #890645 The command "pip install b2" does seem to work, although I haven't done exhaustive testing.
I ran the following commands (as root): apt install python-arrow python-requests python-six python-tqdm python-dateutil python-funcsigs python-concurrent.futures pip install b2 And then tried a duplicity --collection-status (also as root) which worked. Note: I used apt to install the depencies for b2 which were in the repository. Alternatively, maybe those should bacomee dependencies of duplicity? Of course, the comments that I suggested putting in the README should probably go in a News entry, as you had suggested. -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (900, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.14.0-3-amd64 (SMP w/4 CPU cores) Locale: LANG=en_IE.utf8, LC_CTYPE=en_IE.utf8 (charmap=UTF-8) (ignored: LC_ALL set to en_IE.utf8), LANGUAGE=en_IE.utf8 (charmap=UTF-8) (ignored: LC_ALL set to en_IE.utf8) Shell: /bin/sh linked to /bin/bash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages duplicity depends on: ii gnupg 2.2.4-3 ii libc6 2.26-6 ii librsync1 0.9.7-10+b1 ii python 2.7.14-4 ii python-fasteners 0.12.0-3 ii python-lockfile 1:0.12.2-2 Versions of packages duplicity recommends: ii python-oauthlib 2.0.6-1 ii python-paramiko 2.0.0-1 ii python-pexpect 4.2.1-1 ii python-urllib3 1.22-1 ii rsync 3.1.2-2.1 Versions of packages duplicity suggests: ii lftp 4.8.1-1 pn ncftp <none> ii python-boto 2.44.0-1 pn python-cloudfiles <none> pn python-gdata <none> pn python-swiftclient <none> pn tahoe-lafs <none> -- no debconf information
