package samba4 4.0.0~alpha18.dfsg1-4ubuntu2 failed to install/upgrade: ErrorMessage: subprocess installed post-installation script returned error exit status 126

[Kevin Freeman]

This error occurred when I was updating packages and performing a distribution upgrade to 12.04 Xubuntu. I'm running a Compaq Presario C500, and so far I also haven't been able to get wireless drivers installed either. Right after the initial install, my USB wireless adapter worked fine even though the native wireless wouldn't run from the computer, but after updating packages neither will work. I am now hard-connected with no wireless options. Attempting to see if system upgrades will help... so far, just more problems.
