CRC config

Host Operating System

# Put the output of `cat /etc/os-release`
PRETTY_NAME="Ubuntu 22.04.2 LTS"

Steps to reproduce

1. Follow the instructions listed in https://github.com/crc-org/crc/wiki/Debugging-guide
2. crc ip returns 127.0.0.1
3. ssh -i ~/.crc/machines/crc/id_ecdsa -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null core@127.0.0.1 returns core@127.0.0.1: Permission denied (publickey).

Expected

SSH into the VM should be possible. However, could it be due to the fact that crc ip is returning the IP address of the loopback interface, and should return a 192.168.x.x IP instead?

ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enp3s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

    inet6 fe80::7656:3cff:fe56:f11e/64 scope link
       valid_lft forever preferred_lft forever
4: enp3s0f1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 74:56:3c:56:f1:1f brd ff:ff:ff:ff:ff:ff
5: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
    link/ether 52:54:00:d5:4d:5a brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0
       valid_lft forever preferred_lft forever

Worth noting that what prompted me to try to SSH into the VM is the fact that the OpenShift cluster is appearing as Unreachable (I’ve read through this previous issue by the way: https://github.com/crc-org/crc/issues/1888).

Logs

Before gather the logs try following if that fix your issue

$ crc delete -f
$ crc cleanup
$ crc setup
$ crc start --log-level debug

The cluster starts without visible issues, without needing to delete the existing install.
