[errors.ubuntu.com bug bridge]

The Ubuntu Error Tracker has been receiving reports about a problem regarding ubuntu-release-upgrader. This problem was most recently seen with version 1:0.190.7, the problem page at https://errors.ubuntu.com/problem/0dbbd6e02c98205ac3c1933ce9fc3b64577f1e34 contains more details.

[Impact]
check-new-release-gtk crashes during every use for Lubuntu users on Ubuntu 12.10

[Test Case]
1) Install Lubuntu 12.10
2) Boot up the system (alternatively run /usr/lib/ubuntu-release-upgrader/check-new-release-gtk)
3) Observe a crash regarding check-new-release-gtk and being unable to import WebKit

[Regression Potential]
None as we are just adding a dependency

This because gir1.2-webkit-3.0 is a recommends only and Lubuntu in Quantal does not / did not install recommends by default.

[Brian Murray (brian-murray)]

Here is the Traceback:

Traceback (most recent call last):
  File "/usr/lib/ubuntu-release-upgrader/check-new-release-gtk", line 102, in new_dist_available
    self.build_ui()
  File "/usr/lib/ubuntu-release-upgrader/check-new-release-gtk", line 120, in build_ui
    from gi.repository import WebKit
ImportError: cannot import name WebKit

Looking at some of the instances on errors we can see that this only affects Lubuntu.

[Brian Murray (brian-murray)]

A default Lubuntu install on 13.04 has gir1.2-webkit-3.0 installed so this particular fix does nothing but is still good to get in.

I installed ubuntu-release-upgrader from quantal-proposed and confirm that check-new-release-gtk now works and webkit was installed.

[Brian Murray (brian-murray)]

gir1.2-webkit-3.0 is already installed on a default 13.04 lubuntu install so marking as verification-done-raring.
