Update to Oneiric fails: apt_btrfs_snapshot.py, line 31: TypeError: __init__() takes at most 7 arguments (9 given)

[Tristan Schmelcher]

I am trying to update to Oneiric but it's failing every time. I tried once with the GUI and then twice with do-release-upgrade. In the output from do-release-upgrade it says to open a bug. The failure occurs during the "Calculating the changes" step. When running do-release-upgrade, a Python exception trace can be seen from inside the "apt_btrfs_snapshot.AptBtrfsSnapshot()" call.

This is a relatively new machine with a fresh Natty install. I am not using btrfs.

Thanks for your bugreport.

This is a bug in the code that is triggered by certain /etc/fstab entries, its fixed now and you should be able to upgrade now.
If its still failing, please check that /var/log/dist-upgrade/main.log contains version 1:0.152.25.1 (that is the version with the
fix).

No longer occurring. Thanks for the quick turnaround.
