I had a problem on ubuntu when running "sudo apt-get dist-upgrade" and wanted to report how I solved it. Hopefully this helps anybody with similar problems.
I always got the error message:
Code:
Setting up libxml-sax-perl (0.96+dfsg-2) ...
dpkg (subprocess): unable to execute installed post-installation script: Exec format error
dpkg: error processing libxml-sax-perl (--configure):
subprocess installed post-installation script returned error exit status 2
Errors were encountered while processing:
libxml-sax-perl
E: Sub-process /usr/bin/dpkg returned an error code (1)
The problem is in libxml-sax-perl.postinst which does not seem to be executable.
I did not install any perl packages manually by cpan and found the solution in
http://ubuntuforums.org/archive/inde...t-1342009.html where it was only one part of a bigger problem.
I created a backup file (always a good idea) of my libxml-sax-perl.postinst:
Code:
sudo cp /var/lib/dpkg/info/libxml-sax-perl.postinst /var/lib/dpkg/info/libxml-sax-perl.postinst.bak0
I deleted the old file:
Code:
sudo rm /var/lib/dpkg/info/libxml-sax-perl.postinst
Created a new file:
Code:
sudo vi /var/lib/dpkg/info/libxml-sax-perl.postinst
With the following content (copied from the link mentioned above):
