Host Key algorithm

Hi team,

with the latest update of Openssh 8.8/8.8p1 they diabled ssh-rsa as the Host Key algorithm because of security concerns, see 'potentially-incompatible changes' in

So using this up-to-date version, I am no longer able to access

using `ssh`, fails with 

`Unable to negotiate with port 22: no matching host key type found. Their offer: ssh-rsa,ssh-dss`

explicitly enabling that legacy SHA1 algorithm with `ssh -oHostKeyAlgorithms=+ssh-rsa` I can connect.


Is there any information on if / when will support up-to-date algorithms for verifying the Host?

Or am I completely wrong and need to change my client?

Dupliacte. See this related question.

Solved now. You can remove the +ssh-rsa entry from the config file
