E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem. E: _cache->open() failed, please report.

try manually removing ghostscript and re-run dpkg --configure -a

Thanks for your bugreport.

Could you please try the intrepid dpkg version in
https://edge.launchpad.net/~mvo/+archive

It should fix the issue, its a bug with inconsistency in the dpkg triggers database.
You will need to manually download it and then install it with dpkg -i

Thanks,

Hello,

the workaround:

TEST CASE:
 1. when the system is in incosistent state (e.g. because of bad xine update) run: sudo dpkg --configure -a
 2. verify that it does not behave corretly anymore and errors out
 3. install the updated version of dpkg (with wget and dpkg -i)
     wget https://edge.launchpad.net/%7Emvo/+archive/ppa/+files/dpkg_1.14.20ubuntu6.1_i386.deb
     dpkg -i dpkg_1.14.20ubuntu6.1_i386.deb
 4. verify that it installs correctly and runs some pending trigger actions
 5. run "sudo dpkg --configure -a" and verify that this works without error

Solved my problem :-)

Thanks a lot.
