Public bug reported:
This is a fresh install from a Xenial daily today. All I've done post-
install is configure networking, add a ppa, update the apt-cache and
dist-upgrade. Then I installed MAAS to the machine.
Now I am running a script we have to configure MAAS for Certification
and discovered a part that does a dpkg query is failing. On further
digging, it looks like dpkg is not able to properly query the database.
For example:
bladernr@critical-maas:~$ dpkg -l |grep vim
ii vim 2:7.4.826-1ubuntu3
amd64 Vi IMproved - enhanced vi editor
ii vim-common 2:7.4.826-1ubuntu3
amd64 Vi IMproved - Common files
ii vim-runtime 2:7.4.826-1ubuntu3
all Vi IMproved - Runtime files
ii vim-tiny 2:7.4.826-1ubuntu3
amd64 Vi IMproved - enhanced vi editor - compact
dpkg tells me I have vim installed. Now I try this:
bladernr@critical-maas:~$ dpkg -p vim
dpkg-query: package 'vim' is not available
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.
man says this:
-p, --print-avail package-name...
Display details about package-name, as found in
/var/lib/dpkg/available. Users of APT-based frontends
should use apt-cache show package-name instead.
installing packages does not update this file, apparently. This seems
to be a regression as this works fine in Trusty.
Example: vim was installed via apt-get on Trusty here and dpkg -p works:
bladernr@sulaco:~$ dpkg -p vim

Description: Vi IMproved - enhanced vi editor
Vim is an almost compatible version of the UNIX editor Vi.
.
Many new features have been added: multi level undo, syntax
highlighting, command line history, on-line help, filename
completion, block operations, folding, Unicode support, etc.
.
This package contains a version of vim compiled with a rather
standard set of features. This package does not provide a GUI
version of Vim. See the other vim-* packages if you need more
(or less).
