Comment 2 for bug 421838

This is after a migration 10.04 -> 12.04.1 and I've got something similar here:

$ sudo apt-get install uswsusp
Reading package lists... Done
Building dependency tree
Reading state information... Done
uswsusp is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
1 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.

Setting up uswsusp (1.0+20110509-2ubuntu1) ...
dpkg: error processing uswsusp (--configure):
 subprocess installed post-installation script returned error exit status 128
Errors were encountered while processing:
 uswsusp

E: Sub-process /usr/bin/dpkg returned an error code (1)

The upgrade process should do better error reporting here. What's 'status 128'? And who actually gave that exit status?
