It depends on how you installed Koha in the first place. Did you install 
using the Debian packages (sudo apt-get install koha-common)?

If you did, an upgrade is as easy as this:

sudo apt-get update
sudo apt-get upgrade

This will upgrade to the latest minor version, e.g. from 19.11.10 til 
19.11.13.

If you want to upgrade to a newer major version (e.g. from 19.11.x to 
20.05.x) you need to adjust the file /etc/apt/sources.list.d/koha.list 
before you do "sudo apt-get update". See "Pick which Koha version to 
follow" on the following wiki page for an idea of what you need to do.
https://wiki.koha-community.org/wiki/Koha_on_Debian#Pick_which_Koha_version_to_follow

Then, after adjusting /etc/apt/sources.list.d/koha.list you should be 
able to upgrade with the same commands:

sudo apt-get update
sudo apt-get upgrade

Sometimes this will not upgrade Koha, because it is "held back" (I think 
this happens when the upgrade means you have to install new packages on 
the server, e.g. new Perl modules). In that case you have to try again 
with this command:

sudo apt-get dist-upgrade

Remember to always scan the output of these commands for any error 
messages related to the upgrading of the Koha database.

Good luck!
