[Bug 878797] Re: Internal error installing a .deb is not verbose enough

[Matthew Paul Thomas]

Thanks for the thoughtful report. However, the problem isn't quite as it
appears.

dpkg is decompressing the package archive, and then having a problem
with dependencies (bug 869683).

USC is failing to decompress the archive in the first place (bug
868188). It never gets as far as checking the dependencies -- as far as
it can tell, the package is just unreadable.

So USC can't be as verbose as dpkg, because it is experiencing a
different and much simpler error. Probably the error message could be
more precise, but I doubt it could be more detailed.

Title:
  Internal error installing a .deb is not verbose enough

Status in “software-center” package in Ubuntu:
  New

Bug description:
  Downloaded a .deb file from www.google.com/chrome. Double clicked it,
  and Software Centre opened. An error appears which says "Internal
  Error. The file "/path/to/chrome.deb" could not be opened."

  The message is not verbose and doesn't explain what can be done to fix
  it.

  When installing the file using dpkg, a more verbose message about
  dependencies appears:

  dpkg: dependency problems prevent configuration of google-chrome-stable:
   google-chrome-stable depends on libxss1; however:
    Package libxss1 is not installed.
   google-chrome-stable depends on libcurl3; however:
    Package libcurl3 is not installed.
  dpkg: error processing google-chrome-stable (--install):
   dependency problems - leaving unconfigured

  Installing these dependencies allows the package to install.
