[Bug 1116503] Re: Problems installing package signature from Python script

[Till Kamppeter]

I do not use a proxy and my network seems to be working, as I am
regularly updating the system and the updates get downloaded without any
problems. I also can load the key with the gpg utility.

As you can see below I am using the Aptdaemon compat layer, packagekitd
is not installed.

Do I then still have to test PackageKit >= 0.8.x? Probably a fix there
will not help much as standard installations of Ubuntu use aptdaemon.

Adding aptdaemon task.

Title:
  Problems installing package signature from Python script

Status in “aptdaemon” package in Ubuntu:

Status in “packagekit” package in Ubuntu:
  New

Bug description:
  I use PackageKit to auto-download printer driver packages using the
  script /usr/share/system-config-printer/install-printerdriver.py (part
  of the system-config-printer-gnome package). For Epson's drivers the
  signature with ID 8AA65D56 is needed and the "gpg" command line tool
  has no problem to load it:

  ----------
  till at till-lenovo:/usr/lib/cups/backend$ gpg --recv-keys 8AA65D56
  gpg: requesting key 8AA65D56 from hkp server subkeys.pgp.net
  gpg: key 8AA65D56: "Seiko Epson Corporation (Epson Inkjet Printer Driver) <epson-linux-inkjet at avasys.jp>" not changed
  gpg: Total number processed: 1
  gpg:              unchanged: 1
  till at till-lenovo:/usr/lib/cups/backend$
  ----------

  So it exists and is valid.

  But if I let package kit install it via its Python bindings I get

  ----------
