In order to be able to remote ssh into the server edit the sshd configuration file. And set the following parameters:

# nano /etc/ssh/sshd_config

Let's disable services that are automatically started but we do not need:

systemctl stop NetworkManager
systemctl disable NetworkManager
systemctl mask NetworkManager
systemctl stop serial-getty@ttyAMA0
systemctl disable serial-getty@ttyAMA0
systemctl mask serial-getty@ttyAMA0

For setting up locales see section Locale. On our Home server the configuration should be as follows:

# locale -a
---------------
C
C.utf8
en_GB.utf8
en_US.utf8
nl_NL.utf8
POSIX

# cat /etc/default/locale
--------------------------

#  File generated by update-locale
LANG=en_US.UTF-8

LC_TIME="nl_NL.UTF-8"
LC_NUMERIC="nl_NL.UTF-8"
LC_MONETARY="nl_NL.UTF-8"
LC_PAPER="nl_NL.UTF-8"

When getting the following message: “key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details”. It is a warning message. A warning does not stop the procedure. You can continue upgrading your system even if you see this warning message during an update.If you don’t like seeing the warning message, you can take some manual steps to get rid of it. Import the key:

# apt-key list
--------------
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).

The offending key is the first one (Mike Thompson). You should the last 8 characters (excluding the space) under the line after pub. So from the line “A0DA 38D0 D76E 8B5D 6388 7281 9165 938D 90FD DD2E”, I’ll take the last 8 characters “90FD DD2E”, remove the space and then use it to import the GPG key in its dedicated file under the /etc/apt/trusted.gpg.d directory:

sudo apt-key export 90FDDD2E | sudo gpg –dearmour -o /etc/apt/trusted.gpg.d/mikethompson.gpg

I created a new file mikethompson.gpg here The filename does not matter but it’s good for identification. If the command runs successfully, you won’t see any message. You can verify that by checking if the newly created gpg file exists or not.
