I moved to an Ubuntu VM and did a fresh installation. I am however still unable to set the ssh connection…
Agent exited with code 255: Permission denied, please try again.
Permission denied, please try again.
When I use the ssh -T -oStrictHostKeyChecking=no [inuxrootuser]@192.168.1.100 the connection works just fine.
@louis you tell to use the “site user”, do you mean “cmkadmin”? That is only the checkmk user and has no “account” for SSH in the underlying ubuntu system.
