Graphical update fails

[Wolf Rogner]

Using Software-updater in Ubuntu 14.10 downloads changes but refuses to carry them out when OK is pressed.

The software updater queries the repositories and returns a list of available upgrades.
When choosing OK (selection stopped working a while ago), the download dialog appears but renders a failure notice (check internet connection - which is working perfectly fine).

This happens regularly.

Doing the upgrade in a terminal works first time.

Observed behaviour:

Sometimes IPv6 address resolution appears during download of package lists (which breaks regularly).

The query progress bar in the graphical interface jumps erratically instead of running smoothly (might be an indication of failed name resolution or package retrieval)

No changes in network configuration on my side (just in case someone might wonder)

Download from the main server is extremely slow (40-50k/s on a 45Mb/s line)

Please try launching update-manager from a terminal via "update-manager --debug" and report back. Thanks!

[Wolf Rogner (war-rsb)]

Tried it, worked (unexpectedly). Running without the debug option produces the same dialog (Failed to download packages...)

Here is the failure dialog

It regularly comes when calling update-manager from the dash / launchbar

As mentioned before, doing a textual upgrade (apt-get) does not influence the behaviour of the graphical update manager

[Wolf Rogner (war-rsb)]

After some more observation and reading around I tried to deactivate IPv6.

Even with IPv6 disabled, the graphical update-manager regularly fails to download the packages. Doing this from the terminal works fine on every attempt.

Have no more ideas as to what to try or adjust
