I need to upgrade Debian to a specific minor release : from 10.9 to 10.10 (to be iso with another environment). The problem is if I run apt-get update then apt-get dist-update : the release is 10.11...

Thanks

Debian doesn’t keep old point-releases in its main archives; see Why do previous versions of Debian packages vanish in the package repositories? (highly relevant for version-controlled system configuration) for more details on that.

There is however a workaround: it is possible to determine the timestamp for a given release, and use that with snapshot.debian.org (see How to Debootstrap specific version in Ubuntu or Debian?). In your case:

$ wget -q -O - https://cdimage.debian.org/mirror/cdimage/archive/10.10.0/amd64/jigdo-bd/debian-10.10.0-amd64-BD-1.jigdo | gunzip | awk -F= '/snapshot.debian.org/ {print $2}'
http://snapshot.debian.org/archive/debian/20210620T161105Z/ --try-last

Use that timestamp in an entry such as

deb http://snapshot.debian.org/archive/debian/20210620T161105Z/ buster main

and (temporarily) disable the main Debian 10 entries — running apt update && apt upgrade will then upgrade you to the package versions as they were when Debian 10.10 was released.

  • It's worth pointing out that this is not necessary in most cases – debian is a distro both very concerned and experienced with package management and not making breaking changes. In other words, any software that could be compiled the day Debian 10 is released should still compile on a fully updated debian 10 the day debian 10 goes end-of-life. – Marcus Müller Feb 28 '22 at 17:33

    @MarcusMüller I went into some detail regarding that aspect in the linked answer. – Stephen Kitt Feb 28 '22 at 17:37
