geoipupdate is not found, you need to change
/etc/apt/sources.list to include contributed packages.
/etc/apt/sources.list and look for:
and change to:
Now try the
apt install geoipupdate again, it should work now.
Debian should have installed at least the 3.1.1 version of
geoipupdate. You'll see the version when it installed, this becomes important later. To check it:
You have all the bits we need, we'll set them up later.
Visit the Maxmind web site.
Read down the page and click on 'SIGN UP FOR GEOLITE2'. Create your account, I selected 'Internet Security' for 'Intended Use'.
Once you have the account, go to Maxmind's Account portal and login. You can also get there from the head and shoulders icon in the menu bar on their site.
Once logged in, you land on a page that appears to have nothing apart from frightening messages. However, scroll down, looking In the menu on the left-hand side and click on 'My License Key' under Services.
Once there, copy and store your Account/User ID, you'll need it later.
Click on 'Generate new license key'.
Enter a name for the key, I'm using a machine name.
TIck the radio button to select use with geoipupdate version 3.1.1.
Click on 'Confirm'.
This is the only time you will see the full version of the key, so copy and paste it somewhere safe. There's an icon next to the key that will copy it to your clipboard. If the next step fails, you can edit the
geoipupdate config file from the information you have.
Now click on 'Download Config' - this will create a local file called GeoIP.conf.
The Debian installation will have created
/etc/GeoIP.conf for you. The file pre-dates the Maxmind decision to ask you to sign up for a free license, ignore the comment above the AccountID line. You need to set the:
GeoLite2-ASN GeoLite2-City GeoLite2-Country
you can do this by copying the downloaded file into place, or by editing the file. You'll need to sudo your edit or cp.
and it should download a new set of files. These will be put in
/var/lib/GeoIP and an
ls will show them.
The Debian installer will have installed a cron file
that updates the files automatically once a week. I suggest that you change the time of day somewhat so that you are not clashing with other Debian systems in your timezone.
