Upgraded my machine to macOS Ventura from Big Sur and got into issues with git over ssh to our BitBucket server:
$ git clone ssh://[email protected]:7999/com/tangix-virtualtester.git
Cloning into 'tangix-virtualtester'...
[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.
Turns out ssh in macOS Ventura improved security by turning of RSA/SHA1 in the default configuration. Our internal bitbucket server is still requiring RSA/SH1 it seems.
Solution? Add the following to ~/.ssh/config to re-enable RSA/SHA1:
Host xxx.xxx.xxx
HostkeyAlgorithms +ssh-rsa
PubkeyAcceptedAlgorithms +ssh-rsa
Seems like this change comes from OpenSSH upstream and was rolled into macOS Ventura.
