Resolved Error That is a critical error, migration was stopped

Server operating system version

Ubuntu 22.04

Plesk version and microupdate number

Plesk Obsidian v18.0.44

When I start a migration from one server to another with the plesk migration tool, it throws me the following error:

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.

I check the next article, but doesn´t work for me:

Which may be due?

Hey,

it seems that it has some issues to create the necessary files.
I guess you have changed the IP to 00.00.00.000 - yes?

What happens if you just try to execute the command it states via SSH?
rsync -r --chmod=Fu=r,Du=rwx,go= --timeout=30 -e 'ssh -i /usr/local/psa/var/modules/panel-migrator/sessions/20230111115500/ssh-keys/id_rsa.00.00.00.000 -p 22 -o PasswordAuthentication=no -o StrictHostKeyChecking=no -o GSSAPIAuthentication=no' /usr/local/psa/admin/plib/modules/panel-migrator/backend/lib/python/parallels/plesk/source/legacy/extras/plesk_17_0_pmm_shared/ [email protected]:/root/plesk_migrator/plesk_migrator-qx29hxodyyr8w019ohzo9d7rq8p36fup/pmm_agen

There must be some error given?

Best,
Mitti

If I run the command indicated in the Plesk error from SSH it displays the following information (In the place where the 00 is shown is the real IP)

Warning: Identity file /usr/local/psa/var/modules/panel-migrator/sessions/20230111115500/ssh-keys/id_rsa.00.00.00.000 not accessible: No such file or directory.

Regards.

Finally I have done the migration through ssh keys.

I checked which algorithms the source server supports with: ssh -Q kex
which was:

Code:
diffie-hellman-group1-sha1
diffie-hellman-group14-sha1
diffie-hellman-group-exchange-sha1
diffie-hellman-group-exchange-sha256
ecdh-sha2-nistp256
ecdh-sha2-nistp384
ecdh-sha2-nistp521
diffie-hellman-group1-sha1
[email protected]

then i generated new key files with ssh-keygen -t ecdsa -b 521 because ecdsa is supported.

now migration works
