To keep your server's operating system up-to-date, you may want to configure the Parallels Installer so as to notify you of new update packages available from your vendor. Note that the Parallels Installer will not install any packages without your confirmation, it will only notify you.
Note: This option is available only for RPM-based operating systems. For DEB-based systems, vendor updates repository is added to the sources list of the APT package manager.
To have the Parallels Installer check vendor sites for updates:
/root/directory on the server, or, if you previously created this file, modify it. Add the following line to the file:
ADDITIONAL_SOURCE="<type>, <priority>, <url>, <username>, <password>"
where you should replace
<type> with repomd value,
<priority> with a number from 1 to 999 (999 is the highest priority), and
<url> with a URL of the vendor updates source. The values
<password> are required only if your vendor's site requires authentication.
