2. sudo apt install libnet-cidr-lite-perl libtext-csv-xs-perl libgeoip2-perl

3. tar xf xtables-addons-3.13.tar.xz
4. cd xtables-addons-3.13/
5. ./configure
6. make
7. sudo make install
8. sudo depmod -a
9. sudo modprobe x_tables
10. sudo modprobe xt_geoip

You have to install the linux-headers-4.9.0-19, but the latest version is linux-headers-4.19.0-27 in Debian 10

Do you think it is possible to install on my PROXMOX Linux pve 6.8.12-3-pve?
