Update-Manager crash on update "OSError: [Errno 2] no file or directory: './modaliases'"

[Donovan]

Binary package hint: update-manager

If i try to make the update from Intrepid (8.10) to Jaunty, on the partial update it exit with this error:

**********************************

*************************************
Update-manager package is ver. 1:0.93.35

I've tried too:

- creating the directory ./modaliases in /usr/lib/python2.5/site-packages/DistUpgrade/
- inserting also this directory on the Python file in /usr/lib/python2.5/site-packages/DistUpgrade/DistUpgradeQuirks.py on line 89
- enabling apport in this file /etc/default/apport (with echo enable=1)

But it always stops and i get new errors:

************************************

I noted also some similar bugs like the #335416 but without any working solution for this problem.

I had exactly the same problem, and I also tried creating dir "modaliases".

However, I looked around filesystem and found that there's /tmp/tmp1AYBN/modaliases which was probably created by update manager when I first attempted to upgrade from 8.10 to 9.04

I copied all the files:

cp /tmp/tmp1AYBN/modaliases/* ~/modaliases

And it worked.
