- Plesk for Linux
Is it safe to update system packages using an operating system package manager?
Yes, it is safe, and moreover, we recommend using package managers (for example, "yum" on RedHat-based systems, or "apt-get" on Debian-based systems) to keep the system up-to-date.
On Plesk Obsidian, it can be done in the menu Tools & Settings > System Updates.
If Plesk is installed inside a container, the kernel updates are not necessary - the kernel should be upgraded from the Hardware Node.
If Plesk is installed on a hardware server, the kernel updates are recommended if there are only vendor's repositories configured. Otherwise, if the custom repositories provide new kernels, it is better to have the kernel manually updated from the vendor's repository. The reason is simple: major troubles are caused by kernels with GRSecurity patches applied. Plesk is not designed for working with such configurations.
Visiting this article a while back I'm sure it used to recommend excluding certain packages from the system updater, has this now changed? I have excluded sendmail, bind-chroot and caching-nameserver in my yum.conf.
I have checked the previous revisions of this articles. There were no recommendations regarding specific packages.
Must have been a similar article then Ivan, I'll see of I can find it! Thanks.
Ok, feel free to contact us back.
Just to make sure, i have upgrade to Plesk onyx 17.8. Now Plesk is asking me to update system files via Plesk. Is this ok? or is safe to do so via Plesk web? If it is safe, would you recommend it to be automatically installed?
It is considered to be safe to install such updates automatically using Plesk. Plesk uses same commands as if it is done manually in CLI.
Please, bear in mind that upgrade of some packages like Apache may cause short websites accessibility interruption.
Robin Tong I remember this as well. It's been a while. Here is the Archive.org version of the article you are remembering... https://web.archive.org/web/20130816063825/http://kb.parallels.com/en/234
I don't think it's relevant any longer.
