package libiscsi2:amd64 1.12.0-2 failed to install/upgrade: package libiscsi2:amd64 is already installed and configured

I am terribly sorry, but the problem might be due to my PC. Not long ago I damaged it with liquid, fortunately the computer works fine. Thank you and good luck. Sincerely yours, Hristo Mitkov.
