Public bug reported: ## Issue at hand
Yesterday's livefs builds for Lubuntu and other flavors were failing[1] due to an issue with dependency resolution. efivar and mokutil both depend on libefivar1. efivar (both the name of the source and of a binary, referring to the source in this case) was updated for the time_t transition, causing a binary package rename from libefivar1 to libefivar1t64, but still Providing libefivar1. efivar is installed at an earlier stage of the build (and is in one of the more core seeds), which pulls in libefivar1t64. mokutil then tries to bring in libefivar1 at a later stage, but fails because libefivar1 existed as an NBS binary. Specific error: [2024-03-07 00:41:28] lb_chroot_install-packages live [...] Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libefivar1t64 : Breaks: libefivar1 (< 38-3.1) Germinate did track that libefivar1 is provided by libefivar1t64, but does not reflect that further up in the stack. [1] https://launchpadlibrarian.net/717897291/buildlog_ubuntu_noble_amd64_lubuntu_BUILDING.txt.gz ## Steps to reproduce Prereqs: - A noble container or system with root access (run the following commands in a root shell) - A decent internet connection -------- apt -y install live-build livecd-rootfs cd <SOMEWHERE> mkdir build && cd build && mkdir auto for i in /usr/share/livecd-rootfs/live-build/auto/*; do ln -s $i auto/; done # In auto/config, change line 42 to read the following (with proper indentation of course): ## i386|amd64) MIRROR=https://snapshot.ubuntu.com/ubuntu/20240307T003614Z/ ;; export SUITE="noble" ARCH="amd64" PROJECT="lubuntu" lb clean --purge lb config lb build ## Potential Solution The absolute best potential solution I can think of would be to ask Germinate to examine Provides prior to adding the package. I could see something like this being around line 1825 in germinate/germinator.py. What I'd like to know from the current Germinate maintainers is, what do you think? Is this something Germinate should be able to plan for? Any rules of thumb when doing dependency resolution? Is there a Somewhat Easy way of falling back to apt for this? ** Affects: germinate (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2056483 Title: Provides and NBS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/germinate/+bug/2056483/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
