[Bug 1307917] Re: installing driver hangs indefinitely

[jim parris]

I also have this problem with Epson printer drivers.

There is something wrong with the repo id that it is passing to the
python script.  It is passing six (6) arguments when the script only
takes three.

The third argument is the url, which is apparently wrong.  The last
three are irrelevant.

Run the script with only two arguments, and it will work fine - there is
logic for it.

Commented version of the python script:
https://fossies.org/dox/system-config-printer-1.4.4/install-printerdriver_8py_source.html

Argument in question (remove this):

http://download.ebz.epson.net/dsc/op/stable/debian/

19  try:
20  repo_gpg_id = sys.argv[3]
21 except:
22  repo_gpg_id = None

------------------------------------------

As root, run:

/usr/bin/python /usr/share/system-config-printer/install-
printerdriver.py epson-inkjet-printer-escpr deb

And then you can go back and add your printer like normal.

Title:
  installing driver hangs indefinitely

Status in “packagekit” package in Ubuntu:
  Incomplete
Status in “system-config-printer” package in Ubuntu:
  Incomplete

Bug description:
  While installing a printer driver, I get the usual progress bar modal
  window (title: 'Installing driver epson-inkjet-printer-escpr',
  content: 'Installing ...'). It just stops and hangs indefinitely at
  about 50% progress though.

  I've inspected pstree, and the offending command line seems to be:

  /usr/bin/python /usr/share/system-config-printer/install-
  printerdriver.py epson-inkjet-printer-escpr deb
  http://download.ebz.epson.net/dsc/op/stable/debian/ lsb3.2 main
  E5220FB7014D0FBDA50DFC2BE5E86C008AA65D56

  Running it from the command line outputs the following two lines:

      Signature key supplied
      pk.install_signature

  .. and then it hangs as well.

  I've attached an strace -f of the above command.  The trace doesn't
  actually end (the process hangs as before), but does stop outputting
  new system calls.
