Another way to determine install dates with dpkg is to look in the /var/log/dpkg.log* files as per http://www.linuxquestions.org/questions/ubuntu-63/list-packages-with-install-date-622335/

I am trying to remove a partially installed package. There is an error in the package - I think the key error message is:

update-alternatives: unknown argument `--remove-all’

Now I can’t figure out how to get rid of the darn thing. I have tried:

sudo dpkg --purge remove ghostscript

which fails (with the above error message).

The state of of the package is:

dpkg -l | fgrep ghostsc
pF ghostscript 8.63.dfsg.1-0ubuntu6.4 The GPL Ghostscript PostScript/PDF interpreter

What is the dpkg command to remove a faulty partially installed package?

I’ve looked everywhere for this: does anyone know how I can take the results of an “apt-cache depends xyz” command, and then easily determine which of those dependencies are (or are not) already installed?

OK, how do I find out when a package was installed on my machine? Or if I want to sort my packages by install date?
Thanks,

ls -tl /var/lib/dpkg/info/ | less

Please refer to aptitude i.s.o. dselect as being the text-based tool on top of dpkg.
