Using Linux Mint 22 – System Info –>
System
I keep getting error code (1) when I try to install an apt. Checking further it was indicating postfix was not installed or damaged. I then used SU and update and remove postfix. When I try to reinstall it fails:
dpkg: error processing package postfix (--configure):
installed postfix package post-installation script subprocess returned error exit status 75
Processing triggers for ufw (0.36.2-6) ...
Processing triggers for man-db (2.12.0-4build2) ...
Processing triggers for rsyslog (8.2312.0-3ubuntu9.1) ...
Errors were encountered while processing:
postfix
E: Sub-process /usr/bin/dpkg returned an error code (1)
I also get a popup at startup indicating a system error. I have tried a number of different solutions like sudo apt-get purge postfix then dpkg-reconfigure postfix I select local and still no luck. Also trying to install -f gives same error code 1.

I’m sure more display info would be helpful
