Hello
When attempting to ssh to sandbox-iosxe-recomm-1.cisco.com from ubuntu 22.04, I am receiving the following error:
Unable to negotiate with 131.226.217.149 port 22: no matching key exchange method found.

No problem. Open a terminal windows and execute the following;
sudo nano /etc/ssh/ssh_config
ENTER YOUR PASSWORD
Then copy/paste the following on the end after Host *
KexAlgorithms +diffie-hellman-group1-sha1,diffie-hellman-group14-sha1
Should look like this
Host *
SendEnv LANG LC_*
HostkeyAlgorithms ssh-dss,ssh-rsa
KexAlgorithms +diffie-hellman-group1-sha1,diffie-hellman-group14-sha1

Hi @szglvs,
When that one is down or locked, as it is now, I use the alternate, and vice versa:
