dpkg problem

Had this problem:

 subprocess installed post-installation script returned error exit status 1

And found a solution here

What I did to recover from this problem;

1. Go to /var/lib/dpkg/info
2.  Find the related package problem ended with *.postinst
3. Delete that particular file
4. Try apt-get update again, should be working

Error with debconf

I had this problem just now, making my system half-broke!

"Use of uninitialized value in concatenation (.) or string at /usr/share/perl5/Debconf/DbDriver/File.pm line 44, <DEBCONF_CONFIG> chunk 3."

Searched for the solution and found. To solve,


sudo apt-get install debconf --reinstall

and worked!
