Issue Import WordPress Website: There were issues when transferring source folder

[micheee]

Server operating system version

Ubuntu 20.04

Plesk version and microupdate number

18.0.52.3

I am trying to import a website from another Hoster to our plesk instance, I am using:

# plesk version
Product version: Plesk Obsidian 18.0.52.3
     OS version: Ubuntu 20.04 x86_64
     Build date: 2023/05/16 12:00
     Revision: a3b74dbc9de2e47afd4e532d02fa7759b29d3fa5

The connection can be established via SSH just fine, I can even browse folders on the remote server:



When I try to actually import, the following error is returned:

Executed command:
 scp -r -i /var/www/vhosts/new-somewhere/site-import-key \
   -P 22 -o PasswordAuthentication=no -o StrictHostKeyChecking=no \
   -o GSSAPIAuthentication=no \
   user@somewhere:/html/wordpress/. /var/www/vhosts/new-somewhere/httpdocs/
Output:
error: unexpected filename: .

It seems like scp, due to CVE-2018-20685 disallows the '.' that Plesk generates in the copy-command. Unfortunately, I am unable to change the scp on the receiving side.

I already attempted to set the source document to both "/home/user/html/wordpress/", "/home/user/html/wordpress" (instead of automatic detection) but it did not change the behavior.

I have a feeling that this used to work some time ago — but I can't remember exactly when this was.
