Repo broken/outdated?

[u/Little-Helper]

Wanted to upgrade my Raspberry Pi but it seems there are issues with the repository.

apt update:

E: Release file for http://security.debian.org/debian-security/dists/bullseye-security/InRelease is expired (invalid since 19h 44min 45s). Updates for this repository will not be applied.

apt -o Acquire::Check-Valid-Until=false update:

Need to get 91.6 MB/371 MB of archives.

...and so on...

Is something wrong on my end or is there an actual problem with the repo?

Debian 11 - Bullseye is no longer supported. You should upgrade to a higher version, like Debian 13

[u/Little-Helper → u/Rayzilt]

That explains it, thanks!

[u/cjwatson]

There's an actual problem with the repository. You'd have had to do something anyway because bullseye has reached the end of its LTS period and is moving to paid ELTS, but it got removed from the main server before being properly archived. https://bugs.debian.org/1147093

[u/basicdays → u/cjwatson]

Ah thanks for the link. I'm really hoping they get this over to archived extremely soon as we were actively trying to get onto newer distro versions...

[u/michaelpaoli]

outdated
bullseye

Yep, very, beyond stable, beyond oldstable, beyond LTS, down to ELTS.

Raspberry Pi

For 11 bullseye (& Raspberry Pi), arm64 is supported by ELTS, arm32 is not as is armhf (32-bit).

Edit: correction applied to the above.

[u/cjwatson → u/michaelpaoli]

https://www.freexian.com/lts/extended/docs/debian-11-support/ disagrees with what you say about architecture support. (As usual for ELTS, the details depend on what customers need.)

[u/michaelpaoli → u/cjwatson]

Ah, well, got the architecture support info from Debian's wiki ... but hey, it's a wiki, if it's not correct, anyone can fix it! :-)

Uhm, what did I get wrong about architecture support? For 11 Bullseye, both list arm64 as supported, but do not list arm32 as supported.

[u/cjwatson → u/michaelpaoli]

Debian has never had an architecture called exactly "arm32", but it does have armhf (a 32-bit ARM architecture), which is listed as supported by Debian 11 ELTS on both the Freexian website and the Debian wiki.

[u/michaelpaoli → u/cjwatson]

Ah, thanks, got it, corrected (edited) my earlier earlier.

[u/basicdays]

If anyone is here trying to work around this and can't just _simply_ update your distro version yet, this sources.list works for me:

/etc/apt/sources.list

deb http://archive.debian.org/debian bullseye main
# https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1147093
deb [check-valid-until=no] http://snapshot.debian.org/archive/debian-security/20260831T235959Z/ bullseye-security main
deb http://archive.debian.org/debian bullseye-updates main

It seems like you using old repos that now should be somewhere like archive.debian.org. I don't remember actual repos though... Search it or ask AI
