Hi, it seems quoting your error log that "package postfix 3.1.4-4 failed to install/upgrade: package is in a very bad inconsistent state; you should reinstall it before attempting a removal". To do so I'd recommend following [1] adapted to the package that is causing the issue for you (postfix).
Unfortunately there are not much more logs attached to help any further for now.
