I just got this at bootup in VIvid.

Occured on login to unity.

After kubuntu-desktop install (reconfig to sddm which failed next reboot + replaced lightdm as display-manager)

Subsequent reboot & login resulted in error message about sddm not installed & this error.

Vivid issued this same fault on login, this was Alpha2 install, it didn't seem to affect Alpha1 install on this Dell Vostro 1510. I'm not sure i can add anything more usefull.

[ROCHE (guyroche08-6)]

Booting Ubuntu 15.04
No sound on open first desk (validation password). I use caïro dock because impossible to have a correct colour screen (I think that i don't have correct video driver on my pc (HP dv 2220sf with ATI 4500 video) but AMD drivers don't work).
A problem too : When I try to use (mode degradé) with low video (safety mode), impossible to work on low video and I always must re-install Vivid. No video access.

Seeing this on a fresh install of 15.04 13 March daily.

Actually not fixed in Vivid fully upgraded

[Brian Murray (brian-murray)]

Should be fixed by this upload:

aptdaemon (1.1.1+bzr982-0ubuntu2) vivid; urgency=low

  * debian/patches/lp1356823.diff:
    - fix crash #1356823

[Josh Perkins (perkinsjs83)]

I am still getting the same error on Vivid. It has been fully updated.

[Brian Murray (brian-murray)]

Indeed the errors bucket is reporting this as occurring with the new, supposedly fixed, version of the package.

[Brian Murray (brian-murray)]

Actually, looking more closely the Traceback uses the same bucket but is in a different part of the code.

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/aptdaemon/pkcompat.py", line 599, in _remove_from_connection_no_raise
    self.pktrans.trans = None
AttributeError: 'NoneType' object has no attribute 'trans'
