Question
Debian 11 Bullseye has been released on August 14th, 2021. Does Plesk support this OS?
Answer
Yes, Debian 11 is supported from Plesk Obsidian 18.0.42 version.
At the moment the following components are not available for Plesk installation with Debian 11 OS:
- WatchDog
- ModSecurity Atomic ruleset
- Mailman
- Webalizer
Also PHP handlers up to 7.3 version will not be avaiable on Debian 11 as they has reached their End of Life cycle and were deprecated by PHP project.

The information is accurate enough, but the fact that almost two months after a planned release of a distribution there's still not even an ETA approaches ridiculous.
Hello Marco Teelen Debian 11 Support will be most likely added in 2022, though we have no exact ETA to share yet.
Therefore, I recommend reaching out to us by the end of January 2022, as we might have an update on this.
Hi,
So what do you suggest, for people who did the update automatically?
I don't want to have to downgrade it to debian 10...
Do you have an exact ETA to share?
Hi, any news about Debian 11 support? Thanks.
Took the team 4 month to support Ubuntu 20 LTS after it's been released. Now we're 6 months after the release of Debian 11, and it still isn't supported by Plesk and not ETA is provided. Differences between Debian 10 and Debian 11 are very minimal, I don't get the reason for such a delay, unless Plesk purposely wants to discourage the use of Debian.
In the meantime, new supports for distros such as AlmaLinux and RockyLinux that have 0 user base since they are new have been added, before the new version of Debian that was already a supported OS.
Debian is the mother of all distros, and I find sad to indirectly encourage the use of a mainstream distro such as Ubuntu for server application, when Debian the most standard and reliable distro out there, therefore the best choice for professional applications. Not to mention that Debian and Ubuntu are both given for 5 years lifetime, with options for further support.
Miguel, you asked me to reach out again at the end of January 2022. It's now well into February 2022.
Is there any news? Even an explanation as to why this is apparently such a difficult task would be helpful.
A vague "near future" comment followed by an even vaguer "We might have more information about this three months from now" is not even remotely enough, and you managed to miss even that.
Hello Marco Teelen and Robin Labadie
After further review, Debian 11 support is planned to be added in Plesk Obsidian 18.0.42 which has the release date on the first 15 days of March 2022.
I updated the article accordingly
Great news @Miguel Monteiro thank you for sharing the information.
Please, do support Debian early in the future. Remember that people and companies are choosing a distro based on the support you give to them.
For me, Debian is the most robust distro out there, I would love to see my company's datacenter full of Debian machines rather than fancy "RockyLinux" or else that IMHO adds no benefit to the Linux ecosystem now that CentOS is basically dead.
Miguel,
Glad to hear it. Will it be possible to dist-upgrade an existing debian 10 plesk installation without major difficulties, or will this be another situation like debian 9 - debian 10?
Is there a way to watch the changelog by email or rss?
https://docs.plesk.com/release-notes/obsidian/change-log/
Plesk Obsidian 18.0.42 has been released on 28th February 2022 and the changelog states that Debian 11 is now supported.
Well, seems like Amavis (Plesk Email Security) won't start correctly.

How is there no support for Plesk Premium Mail on Debian 11? Debian 11 was released in August of last year, and we're halfway through May. There's little to no documentation specifying that Premium Mail doesn't work on Debian 11 (you have to dig through to find the "supported O/S list").... This makes it very difficult to do server upgrades/replacements and lifecycle planning, when we receive zero communication from Plesk regarding this. Even searching the error "ERR [panel] Extension kolab does not support Debian 11.3:", yields no answers or communication from Plesk surrounding this... which is incredibly bad for a paid extension.
We are launching new servers with Debian 11, as that allows for significant LTS planning and maintenance. Debian 10 reaches EoL ~ August of this year (not accounting for LTS releases). It just doesn't make sense to launch a new server knowing you'll have to do a dist-upgrade sooner than later.
Debian 11 supported but no chance to install Plesk Premium Mail or Seafile for example.
Can anyone tell me what the heck i going on?

Debian 11 is supported but other components add-ons are not supported at the moment. Debian 11 only just come out for Plesk not long ago. For this reason, I'm not rushing to upgrade yes yet! Just stay with Debian 10.x.x for this reason.
