Make Tails Installer installable through Ubuntu Software
As noted in #11004 (comment 64684), the installation process in Ubuntu has changed in 16.04 with the introduction of their new “Ubuntu Software” (branded version of GNOME Software). My rough notes are:
- Start Ubuntu 16.04 live.
- Choose Try Ubuntu.
- Start Software & Updates.
- Check universe.
- Other Software → Add… → ppa://tails-team/tails-installer.
- Close, Reload.
- Open a terminal.
- Execute `gnome-software`.
But Tails Installer won’t show up in Ubuntu Software until we have AppStream metadata. See #11569 (closed).
Start reverting e74b5eeb to hopefully rescue some strings and translations from there.
Also double-check if GNOME Software is in Stretch by default and if so, consider replacing Synaptic with GNOME Software for all distros. Debian would still need a custom section to configure backports.
