Hi,
after full support, you have :
* LTS (by Debian) : https://wiki.debian.org/LTS
* Extended-LTS (by Freexian) : https://www.freexian.com/
So you have a LTS support until June 30, 2028
Best regards,
Xavier

Dear Sir or Madam,

Dear Sir or Madam,

I would like to inquire about the official End-of-Life (EOL) date of
Debian 12 (\u201cBookworm\u201d), as I have encountered conflicting information.
According to statements from the Proxmox team, the Proxmox Virtual Environment reaches its End of Life alongside Debian 12, which they
indicate is in August 2026.
However, the following official Debian resources list the EOL date as
June 10, 2026:

* https://www.debian.org/releases/oldstable/
* https://www.debian.org/releases/
* https://wiki.debian.org/DebianReleases#Versions_of_Debian_stable

After contacting Proxmox support, I received the following explanation:

\u201cHello Max,

Please see the footnote at the linked page:
"Reminder: the EOL date for the stable release is the date of the next stable release plus one year. For example, Debian bullseye ("buster
+1") was released on 2021-08-14 so Debian buster's EOL is around
2022-08."

Best Regards, Proxmox Office Team\u201d

The footnote can be found in https://wiki.debian.org/DebianReleases#Versions_of_Debian_stable

This information (also referenced in the Debian Wiki) seems to differ
from the fixed date published on the Debian websites.
Could you please clarify which date accurately reflects the End of
Life for Debian 12?
Specifically, I would like to understand whether the EOL is determined
by a fixed schedule or dynamically based on the release date of the subsequent Debian version.

Thank you very much for your assistance.

Kind regards,
*Max Engel*

I don't think this is that useful since Max appears to be using Proxmox,
not Debian. The question is a discrepancy in what Proxmox considers
Debian's EOL date to be.

That would be true if the statement on:

* https://wiki.debian.org/DebianReleases#Versions_of_Debian_stable

about "the EOL date for the stable release is the date of the next
stable release plus one year." were accurate, but as can be seen from
that page, historically that has not been exactly right: 12 days longer
for stretch, about 3 weeks longer for buster, nearly two months for
bullseye, and, if that page is to be believed, two months short for
bookworm. But, the wiki article above is also different from:

* https://www.debian.org/releases/oldstable/

which states 30 June, not 10 June.

So I don't know which, if any of them, is authoritative. My guess, the
page that's on www.debian.org not wiki.debian.org. And that the comment
about "one year after the next release date" is to be considered highly flexible.

So I think Proxmox are probably mistaken, but it's easy to see how that
could happen.

Thanks,
Andy

Hi Max (2026.05.20_12:48:44_+0000)

According to statements from the Proxmox team, the Proxmox Virtual Environment reaches its End of Life alongside Debian 12, which they indicate is in August 2026.
However, the following official Debian resources list the EOL date as June 10, 2026:

On the 11th of July we expect to make the final point release of
bookworm and hand it to the LTS team.

https://release.debian.org/

In August 2025 this date was tentatively earmarked to be in September 2026. But it was brought forward, fairly soon after that.

You can see distro-info-data's record of these changes in git history:

Dear Sir or Madam,

I would like to inquire about the official End-of-Life (EOL) date of Debi

an 12 (?Bookworm?), as I have encountered conflicting infor
mation.

According to statements from the Proxmox team, the Proxmox Virtual Enviro

nment reaches its End of Life alongside Debian 12, which they indicate is i
n August 2026.

After contacting Proxmox support, I received the following explanation:

?Hello Max,

Please see the footnote at the linked page:
"Reminder: the EOL date for the stable release is the date of the next st

able release plus one year. For example, Debian bullseye ("buster +1") was released on 2021-08-14 so Debian buster's EOL is around 2022-08."

This information (also referenced in the Debian Wiki) seems to differ fro

m the fixed date published on the Debian websites.

Could you please clarify which date accurately reflects the End of Life f

or Debian 12?

Specifically, I would like to understand whether the EOL is determined by

a fixed schedule or dynamically based on the release date of the subsequen
t Debian version.

In addition to what other people already replied - we (Proxmox) set our
own EOL dates roughly aligned with when the base Debian oldstable
version is handed over from regular support to LTS.

Our documentation[0] states (note that *at least*):

How long will my Proxmox VE version be supported?

Proxmox VE versions are supported at least as long as the
corresponding Debian version, i.e. approximately 3 years after its
initial release, see Debian lifespan.

In practice this usually means roughly a year of overlap where both the previous, oldstable-based version and the current, stable-based version
are supported. The exact amount of overlap depends on release dates both
on the Debian and our side.

I'll get the docs on our end updated to make this more clear/explicit
and fix the wrong Bookworm EOL date.
