It's not trivial to fix, if it's fixable at all. Adding the Breaks can cause the library to disappear in the middle of the upgrade, because libgcc1 is upgraded first or temporarily removed, which is the reason it's not there. I thought about hacking a workaround into apt that prevents you from removing libgcc-s1 if libgcc1 is installed, but that's not super helpful as you need a current apt. My suggestion is to set XB-Important: yes and Protected: yes on libgcc-s1 such that people cannot easily remove it after it's installed. We can then remove that bit in bookworm. -- debian developer - deb.li/jak | jak-linux.org - free software dev ubuntu core developer i speak de, en

Thanks to bits from the RT. I can't reproduce this issue on a minimal installation, and the upgrade path has also been fixed #972820. -- Phil Morrell (emorrp1) ``` $ sudo sbuild-createchroot --command-prefix=eatmydata --include=eatmydata buster --chroot-prefix=temporary /srv/chroot/temporary ... $ sudo sbuild-shell source:temporary-amd64-sbuild I: /bin/sh # echo 'deb http://deb.debian.org/debian bullseye main' >> /etc/apt/sources.list # cat >> /etc/apt/preferences Package: * Pin: release a=testing Pin-Priority: 1 # apt update Hit:1 http://deb.debian.org/debian buster InRelease Get:2 http://deb.debian.org/debian bullseye InRelease [123 kB] Get:3 http://deb.debian.org/debian buster/main Translation-en [5969 kB] Get:4 http://deb.debian.org/debian bullseye/main amd64 Packages [8214 kB] Get:5 http://deb.debian.org/debian bullseye/main Translation-en [6266 kB] Fetched 20.6 MB in 5s (3751 kB/s) Reading package lists...

# clarify issue in 972936 retitle 972936 removal of libgcc-s1 breaks the whole system fixed 972936 10.2.0-16 # # purely cosmetic, as this specific issue is fixed severity 964477 serious thanks Hi, On Wed, Mar 03, 2021 at 11:31:07AM +0100, Matthias Klose wrote: > https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=964477#69 > now claims this is gone with the removal of gcc-8 It seems there is some confusion between #972936 and #964477, as the bug log of #972936 contains some info that's only relevant for #964477. First, bug 972936: The issue as reported in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=972936#5 was fixed in gcc-10 10.2.0-16 with the change suggested by Julian in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=972936#24 "Mark libgcc-sN with XB-Important/Protected: yes. Addresses: #972936" I can reproduce the original issue when installing libgcc-s1 from bullseye from snapshot based on this link: deb [check-valid-until=no] https://snapshot.debian.org/archive/debian/20201012T00Z/ bullseye main When installing libgcc-s1 from current bullseye, apt is no longer willing to remove libgcc-s1 (without 'do as I say'). Now bug 964477: This bug can be reproduced based on Ryans script: On a buster system: apt-get install -y --no-install-recommends gcc-8 libc6-dev libreoffice Switch the sources.list to a bullseye snapshot from before the removal of gcc-8 (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=964477#64) Then run apt-get -y dist-upgrade to get the error. When trying to upgrade to a current version of bullseye, the issue doesn't show up, because gcc-8 is no longer there. So it seems this issue was resolved with the removal of gcc-8 from testing. I also can confirm that trying to upgrade to a snapshot of bullseye that has gcc-8 works with the packages from Ryan based on this sources entry: deb http://download.opensuse.org/repositories/home:/rpavlik:/bullseye-fix/Debian_Testing/ ./ (which needs https://salsa.debian.org/rpavlik/gcc-upgrade-testcase/-/blob/main/workaround.asc to be accepted by apt) Even though the issue from 964477 is fixed, it's possible that there are similar issue (not related to gcc-8) we are currently unaware of. So it might still be useful to reintroduce the transitional packages, as suggested by David in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=964477#41 Finally, I think 964477 should be marked as serious (even though that's purely cosmetic now, as the bug is fixed).
