Okay, changed it back to confirmed, since you requested that and confirmed its existence at the same time. It is up to someone else to decide if the real problem lies with thunderbird or gnome-software. Thanks!
Maybe my "fix" worked becase I installed thunderbird with apt first and then cleaned the cache, so it's not really a fix. Thunderbird did later appear in gnome-software, but did so in the installed state, not ready to install as it would be desired. ** Changed in: thunderbird (Ubuntu) Status: Invalid => Confirmed -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1682455 Title: thunderbird not available in GNOME Software Status in thunderbird package in Ubuntu: Confirmed Bug description: I am filing this against Thunderbird, even though it also concerns another package (GNOME Software). Essentially, using a freshly installed Ubuntu GNOME 17.04, Thunderbird is not available in GNOME Software (the default software app for this flavour). You cannot find it via search or the packages browser. The only way to install it is via apt-get and even then it doesn't show in Software (see attached picture).
