Look into /var/lib/dpkg/info and find the post install script, should be grub-efi-amd64-signed.postinst. Try to run that script and see what is the actual error that it reports. It is not the issue with adobe-flashplugin package, but another package that was installed earlier. Judging from the fact that it's a grub package it might have come via recent update/upgrade

I checked that out but running the script in konsole only shows black screen.

OK, so it's possible the script does not output anything. What's the exit status reported via echo $? after you run the script ? (Well, in the error message it reports exit status 1), so if it is the case that the script has no output but does return exit status, we'll have to attempt other things to figure out what exactly causes it to exit with error

Sorry, I couldn't understand. What are you asking me to do ?

Run the script. After the script exits, run echo $?
