This post should not be considered an endorsement of Lokinet in any shape or form. Lokinet is currently not in a good state - it has not had a public release since 2022, and most free public exit nodes have gone offline. According to the developers, they are doing major rewrites of the code, and it should not be used in production at the moment.

## Creating the TemplateVM
Currently, the Lokinet client only seem to work well with Debian-based distributions. This means that our template will have to be one of the Debian-based ones. Personally, I use [this script](https://github.com/TommyTran732/QubesOS-Scripts/blob/main/debian-gnome/debian-gnome.sh) to trim down the Debian GNOME template and convert it to KickSecure. KickSecure reduces the attack surface of Debian with a substantial set of hardening configurations, and a nice feature to go with an anonymity network like Lokinet is [Boot Clock Randomization](https://www.kicksecure.com/wiki/Boot_Clock_Randomization) which helps defend against [time-based denonymization attacks](https://www.whonix.org/wiki/Time_Attacks).

Create an AppVM based on the TemplateVM you have just created. Set `sys-firewall` (or whatever FirewallVM you have connected to your `sys-net`) as the net qube. If you do not have such FirewallVM, use `sys-net` as the net qube.
Edit the `/etc/loki/loki.net` and add the exit node you want to use. At the moment, the only free exit node that I am aware of is `euroexit.loki`:

Note that if you already have a PGP key with a passphrase, you can remove it by installing `pinentry-gtk` to `vault`'s TemplateVM, then do `gpg2 --edit-key <key_id>` and `passwd` to set an empty passphrase. The default non-graphical pinentry will just make an infinite loop and will not allow you to set an empty passphrase.

## Split SSH
This part is based on the Qubes Community's [guide](https://github.com/Qubes-Community/Contents/blob/master/docs/configuration/split-ssh.md); however, I will deviate from it to use the PGP keys for SSH instead of generating a new key pair.
