Nor was it in grep-available.
That's because this has relevant information that needs to be kept, that is, it contains a selection (the "install" part). I'll reword the man page comment to clarify this. > Anyways, I got rid of it with > # dpkg -P libsasl2-3:i386 > dpkg: warning: ignoring request to remove libsasl2-3:i386 which isn't > installed > # dpkg -P libsasl2-3 > dpkg: warning: ignoring request to remove libsasl2-3:i386 which isn't > installed > # dpkg -P libsasl2-3 > dpkg: warning: ignoring request to remove libsasl2-3:i386 which isn't > installed > > The second one did the job!

It's not an error it's just a warning, and it means what it says, you tried to remove a non-installed package, which is true. Also with the request to purge the package the selection also went away, as it was marked for puring (the first Status word). > So now > # grep -c not-installed /var/lib/dpkg/status > 0 As expected. > So I am guessing, whatever mechanism you are using to make sure no > non-installed entries remain in /var/lib/dpkg/status misses catching > smaller entries like the above! Not relly! But as mentioned above, I'll clarify this in the man page. Thanks, Guillem
