Dear Sir or Madam,
=20
Dear Sir or Madam,
I would like to inquire about the official End-of-Life (EOL) date of Debian=
12 (=E2=80=9CBookworm=E2=80=9D), as I have encountered conflicting informa=
tion.
According to statements from the Proxmox team, the Proxmox Virtual Environm=
ent reaches its End of Life alongside Debian 12, which they indicate is in =
August 2026.=20
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
=20
After contacting Proxmox support, I received the following explanation:
=E2=80=9CHello Max,=20
Please see the footnote at the linked page:=20
"Reminder: the EOL date for the stable release is the date of the next stab=
le release plus one year. For example, Debian bullseye ("buster +1") was re=
leased on 2021-08-14 so Debian buster's EOL is around 2022-08."=20
Best Regards, Proxmox Office Team=E2=80=9D
The footnote can be found in https://wiki.debian.org/DebianReleases#Version=
s_of_Debian_stable
=20
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?=20
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,
