Univention Bugzilla – Bug 51690
Force UCS-5.0-0 package installation
Last modified: 2021-05-25 16:02:12 CEST
For UCS-5 we decided to change the package repository structure (Bug #51588) and to no longer re-build packages: Since UCS-4.2 (Bug #41608) we mostly import binary packages from Debian directly without rebuilding them from source. Before that we only imported the source packages are re-build everything ourselves. Also since UCS-4.2 we switched the UCS build stamp (Bug #37376) to improve the following issue: Before UCS-4.2 the UCS build stamp was separated by the "." character, which compares *last* to all other separators used in Debian like "+deb10u0" or ".1" for NMUs or "+b1" for BINNMUs. Debian-10-Buster still carries many packages unmodified from Debian-9-Stretch or even older, as no new upstream version was released for years or no changes were done by the Debian maintainer. Some of those packages were rebuild by us and so still carry our UCS build stamp, so version from previous UCS releases still compare later to the version from Debian-10-Buster. On an upgrade from UCS-4.4 to UCS-5.0 those packages would remain installed as the version from UCS-4.4 compares latest. Mostly this is not problematic, but is critical for some packages, for example PERL related packages: Each new PERL release requires a rebuild of many other PERL packages as they contain the ABI version and do not work with previous/later versions. This is done by Debian though the BINNMU mechanism, which is broken due to our rebuilds. As we want to stop re-compiling those packages we have to switch to the Debian-10-Buster packages once even if they sort earlier. This can be done by providing a preferences file, which assigned priority>=1000 to the packages from Debian-10-Buster once during the upgrade to UCS-5.0-0: $ grep ^deb /etc/apt/sources.list deb [trusted=yes] http://omar.knut.univention.de/build2/ ucs_5.0-0/all/ deb [trusted=yes] http://omar.knut.univention.de/build2/ ucs_5.0-0/$(ARCH)/ $ cat /etc/apt/preferences Package: * Pin: release l=Univention Corporate Server, v=5.0.0 Pin-Priority: 1001 I have successfully testes this and it seems to work without problems so far.
Implemented as part of the work on Bug #51588 TODO: Test this when the work on the upgrade path from UCS-4 to UCS-5
I noticed 2 smaller problems: Die folgenden Pakete werden durch eine ÄLTERE VERSION ERSETZT (Downgrade): docker-compose eject ifplugd libfsplib0 libnetpbm10 libtext-charwidth-perl libtext-wrapi18n-perl libtre5 mawk netpbm python-pam python-singledispatch 791 aktualisiert, 252 neu installiert, 12 durch eine ältere Version ersetzt, 10 zu entfernen und 0 nicht aktualisiert. E: Packages were downgraded and -y was used without --allow-downgrades. Error: Failed to execute "apt-get -o DPkg::Options::=--force-confold -o DPkg::Options::=--force-overwrite -o DPkg::Options::=--force-overwrite-dir --trivial-only=no --assume-yes --quiet=1 -u dist-upgrade" exitcode of univention-updater: 1 ERROR: update failed. Please check /var/log/univention/updater.log This can be fixed via ucr set \ update/commands/distupgrade='apt-get -o DPkg::Options::=--force-confold -o DPkg::Options::=--force-overwrite -o DPkg::Options::=--force-overwrite-dir --trivial-only=no --assume-yes --quiet=1 --allow-downgrades -u dist-upgrade' \ update/commands/distupgrade/simulate='apt-get -o DPkg::Options::=--force-confold -o DPkg::Options::=--force-overwrite -o DPkg::Options::=--force-overwrite-dir --trivial-only=no --assume-yes --quiet=1 --allow-downgrades -us dist-upgrade' (In reply to Philipp Hahn from comment #0) > $ cat /etc/apt/preferences > Package: * > Pin: release l=Univention Corporate Server, v=5.0.0 > Pin-Priority: 1001 This should have been "v=5.0-0" and not "v=5.0.0".
(In reply to Sönke Schwardt-Krummrich from comment #2) > This can be fixed via > ucr set \ > update/commands/distupgrade='apt-get -o DPkg::Options::=--force-confold -o > DPkg::Options::=--force-overwrite -o DPkg::Options::=--force-overwrite-dir > --trivial-only=no --assume-yes --quiet=1 --allow-downgrades -u dist-upgrade' > \ > update/commands/distupgrade/simulate='apt-get -o > DPkg::Options::=--force-confold -o DPkg::Options::=--force-overwrite -o > DPkg::Options::=--force-overwrite-dir --trivial-only=no --assume-yes > --quiet=1 --allow-downgrades -us dist-upgrade' AFAICS we have to set these variables via an erratum/prior to the execution of univention-upgrade. Altering these variables during preup.sh is not sufficient/too late.

If the two problems are fixed, the downgrade works as expected.

No, "5.0.0" is correct / wanted. Actually it's a bug in `repop-ng`: $ grep ^Version mirror/ftp/4.4/maintained/4.4-7/dists/ucs4??/Release mirror/ftp/4.4/maintained/4.4-7/all/Release apt/ucs_4.4-0-ucs4.4-7/dists/ucs447/Release test_mirror/ftp/dists/ucs500/Release apt/ucs_5.0-0/dists/ucs500/Release apt/ucs_5.0-0/all/Release mirror/ftp/4.4/maintained/4.4-7/dists/ucs447/Release:Version: 4.4.7 mirror/ftp/4.4/maintained/4.4-7/all/Release:Version: 4.4-7 apt/ucs_4.4-0-ucs4.4-7/dists/ucs447/Release:Version: 4.4.7 test_mirror/ftp/dists/ucs500/Release:Version: 5.0-0 apt/ucs_5.0-0/dists/ucs500/Release:Version: 5.0.0 apt/ucs_5.0-0/all/Release:Version: 5.0.0 Debian recommends [0-9.] only, e.g. <https://wiki.debian.org/DebianRepository/Format#Version>. From that past I remember that `-` was problematic and `Debian 3.1 Sarge` also used `3.1r8`, but still... Patch for repo-ng is pending in my branch - need to fix another problem there.

I was referring to the UCR variables and I still think that the required UCR variables are evaluated before preup.sh is run. (see also below) But your approach to add an additional config file for apt is much better since it affects only the update to UCS 5.0-0 and saves us from fiddling with manually adjusted variables. > Package: univention-updater > Version: 15.0.3-13A~5.0.0.202102201904 > Branch: ucs_5.0-0 > > OK: /usr/share/univention-updater/univention-updater net --ignoressh > --noninteractive OK: univention-upgrade --ignoressh --disable-app-updates > FYI: The Release upgrade is performed by `univention-updater`, which uses > univention.updater.commands::cmd_upgrade respective cmd_dist_upgrade > The release upgrade is performed in phases: > update, pre: > preup, pre: > preup, main: updater/scripts/preup.sh > preup, post: > update, main: cmd_dist_upgrade > postup, pre > postup, main: updater/scripts/postup.sh > postup, post > update, post univention.updater.commands::cmd_upgrade is loaded at the startup of univention-updater and any change of UCR variables in "preup, main" phase does not affect the loaded cmd_upgrade/cmd_dist_upgrade values.
