Hi,

This is actually a feature: The '.' in the package name triggers apt to
interpret the string "streamer0.10-plugins-good" as it doesn't match
a package name as a regular expression (it tries a few other things as
well, but the regex part is the most 'surprising' perhaps).

You can see the same happening with other commands as well:
$ LANG=C apt install streamer0.10-plugins-good -s
[…]
Note, selecting 'gstreamer0.10-plugins-good' for regex 'streamer0.10-plugins-good'
Note, selecting 'gstreamer0.10-plugins-good-dbg' for regex 'streamer0.10-plugins-good'
Note, selecting 'gstreamer0.10-plugins-good-doc' for regex 'streamer0.10-plugins-good'
[…]

Unfortunately we can't display the message we print in such interactive commands
like install in non-interactive commands like show as this would interfere with
the output and break plenty of tools relying on this behavior expecting only valid
(pseudo) package records on show without intermixed "comments".


So, as this isn't a bug per-se and we can't make the behavior more obvious
without introducing breakage, I am closing this report – but still thanks for
taking the time to report it!


Best regards
