Ssh - No matching algo host key

I am trying to ssh from my Mango to Ubuntu and I keep receiving:
“No matching algo host key”

Dropbear v2019.78

OpenSSH_8.9p1 Ubuntu-3, OpenSSL 3.0.2 15 Mar 2022

Any idea?

Can you check if it is the same as

No this is a different story. Windows and putty.
I ssh from Mango (client) to Ubuntu (ssh server)

I recon Mango needs a newer firmware with the latest Dropbear or some walkaround.

I see. Maybe install openssh in Mango router.

hmm You are right. It might be a quick fix for now.

One time:
ssh -oHostKeyAlgorithms=+ssh-rsa root@

echo -e “\tHostKeyAlgorithms ssh-rsa” >> .ssh/config
