'Unable to negotiate with __IP_ADDRESS_ port 22: no matching host key type found. Their offer: ssh-rsa,ssh-dss
While using git clone in PhpStorm, I got an error message:
Clone failed
Unable to negotiate with IP ADDRESS port 22: no matching host key type found. Their offer: ssh-rsa,ssh-dss
Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.
I then made my own RSA key in and saved it on my computer; also registered it on the server (by server host) where I wanted to get git clone. I've also downgraded my latest PhpStorm version. As a last resort I have also reset my computer and reinstalled PhpStorm.
But I still have that error message in my PhpStorm event log.
Plus, when I first got PhpStorm, I could easily get clone successfully, but suddenly after days, I've got event log entries like that.
Can I get a solution about this, OTL
Solution 1:[1]
On Linux/Ubuntu I added the following lines to /etc/ssh/ssh_config
:
PubkeyAcceptedAlgorithms +ssh-rsa
HostkeyAlgorithms +ssh-rsa
I guess it is equivalent (and better) to put the same lines in a separate file in /etc/ssh/ssh_config.d
.
Solution 2:[2]
Check, as in here, if using a private key without passphrase improves the situation.
Check also settings>Version Control>git >SSH Executable
: try system instead of "native", and double-check your %PATH%
(Windows) or $PATH
(Linux/Mac).
On Windows, I would make sure C:\Program files\Git\usr\bin\ssh.exe
comes first.
Solution 3:[3]
Add PubkeyAcceptedAlgorithms +ssh-rsa
and HostkeyAlgorithms +ssh-rsa
attributes.
nano ~/.ssh/config
Host hostname_of_machine
HostName hostname_or_ip_address
User root
IdentityFile ~/.ssh/file.pem
IdentitiesOnly yes
PubkeyAcceptedAlgorithms +ssh-rsa
HostkeyAlgorithms +ssh-rsa
