install missing lang-pack or updates result in a loop

[Sam_]

Was reproducable.
After installation and updating open language-selector from g-c-c or dash.
It searches for missing lang-packs and advises to install missing aspell-de, confirm to install.
Result: the wheel spins forever, no package will be installed. Tested twice.
## Same behaviour with update-manager, comment #2
Workaround: install aspell-de via terminal, afterwards language-selector opens fine without complains.

Open language-selector in a terminal.
Output:
~$ gnome-language-selector

Same issue with update-manager, it pops up, click to install does nothing, the wheel spins endless.

## ctrl+c did nothing so I've killed it on another tab.

[Sam_ (and-sam)]

In the meantime I've assigned to update-manager and add tag language-selector.

[Sam_ (and-sam)]

Few minutes ago update-manager pop-up appears and displayed two updates.
Click on install worked as expected and installed the two packages.
But click on 'check' button results in a loop again and does nothing.

Logout-in didn't help.

## Not reprocable. (video)
Running update-manager with prefix LANG=C via terminal allowed to check package cache.

## Reproducable.
Running it again via terminal without the prefix results in a loop.
$ update-manager

[Sam_ (and-sam)]

Really tricky since there're different results.
On first attempt run 'apt-get update' via terminal.
When there're updates update-manager will pop-up and allows to install them.
When there're no updates, run update-manager from dash or via terminal, it'll allow to check package cache.

Close update-manager.
Afterwards directly run 'apt-get update' again, open update-manager, it loops again on check of package cache.
Output from this procedure is always:
^CTraceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/UpdateManager/UpdateManager.py", line 653, in update_last_updated_text
    def update_last_updated_text(self, user_data):
KeyboardInterrupt

Wait about ten minutes.
Run 'apt-get update' again, open update-manager, it allows installation or to check package cache.

If 'apt-get update' wasn't issued in a terminal before update-manager results in a loop, either on attempt to install or check.
Output from this procedure is always (without updating via terminal before):
^CTraceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/UpdateManager/MetaReleaseGObject.py", line 42, in check
    def check(self):

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

[Sam_ (and-sam)]

Just now without running apt-get update before, update-manager displayed and installed updates.
Afterwards click on 'check' again results in a loop.
Run update-manager via terminal results in the same output as mentioned.

After recent updates today (incl. language-selector and aptdaemon) the loop and not_recognizing_authentication bug 905442 seemed to be solved.
I'll monitor the next days and if it doesn't occur again mark this one as solved.
The attached history.log shows that I had to upgrade via terminal first and after requested reboot update-manager worked flawless.

[Sam_ (and-sam)]

Forgot to mention the python traceback has also vanished, terminal output only displays some gdk-critical and gtk-warnings.

[Sam_ (and-sam)]

Update-manager worked again flawless today. Confirmed from Bug #894671 aptdaemon fixed.
