Provided directory "/tmp" does not exist

Hello,

I have please one question about installation Oxid eshop. I am just
testing actual version from
https://oxidforge.org/download/download-oxid-eshop-6-0-0?wpdmdl=12085
and I have problem with installation on 5. step:

Error while executing command ‘Migration’. Return code: ‘0’.
The command returns the following message:

Provided directory “/tmp” does not exist
ERROR: Issue while inserting this SQL statements:

Path to tmp I wrote in 4. step is correct and writable. What tmp directory should
this be? Does it mean /tmp in operating system, not in web directory?
Please can you explain me how it works and how can I fix it? Thank you
very much.
