Comment 3 for bug 1931801

The Ubuntu version i am Using is Hirsute.

Im on a RPI4.

On previus installs it used the "mail name" during install etc. "rpi4-ubuntudesktop"
To generate the myhostname = rpi4ubuntudesktop and it would just work.

Now myhostname is created as "rpi4ubuntudesktop.." (Notice the two added dots)
Which it didt do before

----

# My main.cf file is not manually edited yet since i have a failed package install
# Everytime i try to install something after installing postfix i get an

1 not fully installed or removed.

Running

Apt install --fix-missing

Reverts me back to the origional install error of postfix

Running

apt remove --purge postfix
# Then
apt install postfix

gives me the same errors as posted before.

This is my /etc/postfix/main.cf file after a failed install
I havent edited anything
