While trying to clone a Git repository on a Ventura virtual machine using SSH, you encounter errors like "Host key verification failed" or "no matching host key type found".
Most frequently, these errors happen due to compatibility issues with the Ventura OS's SSH configuration. As a result, SSH connections to remote hosts that only support SHA1 may fail.
You can resolve this issue by modifying the SSH configuration on your Ventura machine.
To do so, add the following Script Step just before the failing Step:
#!/usr/bin/env bash
cd /Users/vagrant/git
ls -ltr
ls -a
cat .git/config
echo ssh
cd /Users/vagrant/
ls -a
cd .ssh
ls -a
cat config
echo before
a=' '
echo "Host *" >> config
echo "UseKeychain yes" >> config
# Don't forget to edit host name with your own
echo "Host {Host name}" >> config
echo "${a}User git" >> config
echo "${a}PubkeyAcceptedAlgorithms +ssh-rsa" >> config
echo "${a}HostkeyAlgorithms +ssh-rsa" >> config
This Script Step navigates to the Ventura machine's .ssh directory, opens the config file, and adds the required lines to enable the ssh-rsa algorithm for host key and public key authentication.
