I want to login to a remote site <aaaaa.bbbbbbbb.cc> using 'ssh'.
The response I get is "Unable to negotiate with <nnn.nnn.nnn.n> port
<nn>:
no matching host key type found. Their offer: ssh-rsa,ssh-dss".
Yesterday, I updated 'openssh' :
Installed versions: 8.8_p1-r4^t([2021-12-25 06:12:24])
(X ssl -X509 -audit -debug -hpn -kerberos -ldns -libedit -livecd -
pam -pie -scp -sctp -security-key -selinux -static -test -xmss ABI_MIPS="-n32" KERNEL="linux")
Occasionally, I have had a similar problem trying to do this,
but ordinarily it has worked smoothly.
Does anyone have helpful suggestions how to get past the blockage ?

Yesterday, I updated 'openssh' :It sounds like the host may be running an old version of sshd that only offers ciphers that are now disabled by default in newer releases. You
can get round this by enabling those ciphers for this host, with
something like this in ssh_config
Host aaaaa.bbbbbbbb.cc
Ciphers +ssh-rsa

The initial error is about "no matching host key type", so the option
needed would be:
HostKeyAlgorithms +ssh-rsa
