Resolved Error migrating from plesk 12.5 to plesk 17

[Antrax1]

Hi,

I have this error migrating from plesk 12.5 to plesk 17:

Failed to fetch basic information about resellers, clients and domains data from source servers
Cause: Command execution failed on the local server with non-zero exit code.
command: rsync -l --chmod=Fu=r,Du=rwx,go= -e 'ssh -i /usr/local/psa/var/modules/panel-migrator/sessions/20161101090640/ssh-keys/id_rsa.XXX.XXX.XXX.XXX -p 22 -o PasswordAuthentication=no -o StrictHostKeyChecking=no -o GSSAPIAuthentication=no' /usr/local/psa/var/modules/panel-migrator/sessions/20161101090640/ssh_upload.1 root@XXX.XXX.XXX.XXX:/tmp/version
exit code: 255
stdout:
stderr: Permission denied (password).
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at io.c(226) [sender=3.1.1]

That is a critical error, migration was stopped.

IP was changed to XXX.XXX.XXX.XXX

I see this solution https://kb.plesk.com/en/129028 but the solution is install the latest MU and I have the last version.

¿How can solve this?

Can you login as root user via ssh protocol from source server to target server without any problems?

 

[Antrax1]

Yes, I can access the server without any problems. I have tested in the two directions without any problems.

Also i disabled firewall, Fail2ban, modsecurity, and I updated the server 1 to the version 17 of plesk for them two servers have the same version panel.

Do you have root home dir customized as it is described in KB article?

If yes, on the source server, specify correct path to key files in DEFAULT_AUTHORIZED_KEYS_LOCATIONS parameter of
/usr/local/psa/admin/plib/modules/panel-migrator/backend/lib/python/parallels/core/utils/ssh_key_pool.pyfile:

DEFAULT_AUTHORIZED_KEYS_LOCATIONS = [
# On certain configurations, there is only the second file enabled,
# so configure keys in both of the files
'/root/subdirectory/.ssh/authorized_keys',
'/root/subdirectory/.ssh/authorized_keys2'

 

[Antrax1]

No, I have the default dir:

/root/.ssh/authorized_keys
/root/.ssh/authorized_keys2

can it be a problem with the file permissions?
