Is OpenSSH 8.2+ in some Turris OS branch?

I would like to have sk-ssh-ed25519 key support in Omnia.

Hello,

In OpenWrt 19.07 (branches: hbs-hbt-hbk-hbl), there is a version of openssh 8.0p1 and in OpenWrt master (branch HBD), there is version 8.4p1. There might be a way if you want to have it in OpenWrt 19.07, test it and send pull request to OpenWrt packages repository.

More about our branches can be found in our documentation here:
