We want to allow distributions to hook snapd into bash’s “command not found” support. This is the thing that, in regular Ubuntu, prints e.g.
$ httpd No command 'httpd' found, did you mean: Command 'http' from package 'httpie' (universe) Command 'xttpd' from package 'xtide' (universe) httpd: command not found $
(in other distributions it can be interactive, taking you all the way through installing the package and trying the command again).
The effort has several parts. In no particular order:
- make the data available from the store
- on core (at least) pull the data from the store regularly, and have a minimal
command_not_found_handlethat serves data from there
- look into distributing the above data via the debian mirror system, and have apt fetch it as additional metadata for the current
- look into replacing the (currently too slow for core) implementation of command-not-found with the above one in general Ubuntu, consuming the same catalogs as currently.
- support other distributions in adding support for the additional source of packages in command-not-found. SuSE and Fedora do their own thing (and Fedora currently uses packagekit which is single-source, but is moving to just using gnome-software as a backend? perhaps not as the startup time would be a killer). We’re hopeful (but perhaps delusional) that the above faster command-not-found would be good enough to be cross-distro, in the fullness of time.
