system-config-printer found the suitable printer driver for EPSON printer, but can't install

[Naruhiko Ogasawara]

In Ubuntu, very few (EPSON only I know) printer vendor supports automatic driver download feature.
When I tried the feature with EPSON PX-503A in Oneiric and Precise, it worked fine.
But I also tried my new Quantal system, s-c-p seems to found correct the printer driver (see attached screenshot), but not installed when I press "Forward" button; nothing happens and no driver package is downloaded or installed.

Reproduce Process:

1. In s-c-p, click "add" button and select the network printer EPSON PX-503A.
2. Ubuntu says "looking for the drivers...," then attached screenshot is appeared. It seems correct.
3. Press "Forward" button.

Expected Result:

- The found driver package will be downloaded and automatically installed, then we can select the right PPD in s-c-p.

Current Result:

- Nothing happens, and s-c-p says select "Generic" PPD.

I'm not sure which module has a problem (s-c-p or ubuntu-driver), sorry if my choose of the package is wrong.

Status changed to 'Confirmed' because the bug affects multiple users.

[Vincent Thiele (vincentthiele)]

Please fix this for 14.04 LTS.

[Till Kamppeter (till-kamppeter)]

Naruhiko, Vincent, did you test this with 14.04?

Vincent, what is your printer model?

[Ikuya Awashiro (ikuya-fruitsbasket)]

I tried on 14.04, and I could confirm this issue.
Due to this log, it seems to find an old driver.

[Till Kamppeter (till-kamppeter)]

This is a problem with Epson's download server and I have reported it already to Epson.

[Till Kamppeter (till-kamppeter)]

Epson's server is fixed now. Please try again and tell whether the problem is solved.

[Ikuya Awashiro (ikuya-fruitsbasket)]

Hmm, I got the same result.

[Till Kamppeter (till-kamppeter)]

Ikuyam, your lgs seemt to be incomplete. Please run the following command line:

system-config-printer --debug 2>&1 | tee epson-805a-3.log

Try to set up the printer again. You will get a screen offering the downloadable driver. Accept the license and click "Forward". Wait and see what happens. When you asked for setting up the printer manually, click "Cancel" and close system-config-printer, also if something else happens what you expect should not happen. Attch the new log file to this bug report.

[Ikuya Awashiro (ikuya-fruitsbasket)]

It looks good to me.
I don't know why I got a wrong result yesterday.
Anyway, I am sorry for bothering you.
