Cannot (un)install anything: dpkg error code (1)

[haseeb]

I cannot install or uninstall any package or update the os. Anything with apt-get shows the error message like the this -


xxx@yyy:~$ sudo apt-get autoremove
[sudo] password for xxx:

dpkg: error processing install-info (--configure):

Errors were encountered while processing:

Any help?

found a thread here (http://ubuntuforums.org/showthread.php?t=1578263),

the solution from drs305 (http://ubuntuforums.org/member.php?u=223945) solved the problem.

for reference i am also pasting his solution here,


sudo mv /var/lib/dpkg/info/install-info.postinst /var/lib/dpkg/info/install-info.postinst.bad

to undo,


sudo mv /var/lib/dpkg/info/install-info.postinst.bad /var/lib/dpkg/info/install-info.postinst
