Public bug reported: I'm not sure if this is incorrect behavior in schroot or incorrect assumption in sbuild-launchpad-chroot.
I have a system where I was not able to use union, so the focal-amd64 config that was built by sbuild-launchpad-chroot looks like below. When attempting to build from it (sbuild --dist=focal --arch=amd64 --arch- all package.dsc), CHROOT_SESSION_PURGE is set to false. That causes me to take the 'exit 0' path in https://git.launchpad.net/~motu/ubuntu/+source/sbuild-launchpad- chroot/tree/etc/schroot/setup.d/90apt-sources#n39 . The end result is the 'apt.default.mirror' setting is not honored. If you set 'union-type=overlay', then you'll get CHROOT_SESSION_PURGE set to true and it will work as desired. % cat /etc/schroot/chroot.d/focal-amd64 [focal-amd64] type=directory directory=/var/lib/schroot/chroot/focal-amd64 description=Ubuntu focal/amd64 sbuild root-groups=root,sbuild profile=sbuild launchpad.dist=ubuntu launchpad.series=focal launchpad.arch=amd64 launchpad.url=http://launchpadlibrarian.net/475801990/livecd.ubuntu-base.rootfs.tar.gz apt.enable=true aliases=focal-security-amd64,focal-security+main-amd64,focal-security+restricted-amd64,focal-security+universe-amd64,focal-security+multiverse-amd64,focal-updates-amd64,focal-updates+main-amd64,focal-updates+restricted-amd64,focal-updates+universe-amd64,focal-updates+multiverse-amd64,focal-proposed-amd64,focal-proposed+main-amd64,focal-proposed+restricted-amd64,focal-proposed+universe-amd64,focal-proposed+multiverse-amd64,focal-backports-amd64,focal-backports+main-amd64,focal-backports+restricted-amd64,focal-backports+universe-amd64,focal-backports+multiverse-amd64 apt.default.mirror=MY_MIRROR ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: sbuild-launchpad-chroot 0.17ubuntu0.20.10.1~20.04.1 ProcVersionSignature: Ubuntu 5.13.0-28.31~20.04.1-generic 5.13.19 Uname: Linux 5.13.0-28-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.11-0ubuntu27.21 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Tue Apr 12 15:53:54 2022 InstallationDate: Installed on 2020-01-15 (817 days ago) InstallationMedia: Ubuntu 18.04.3 LTS "Bionic Beaver" - Release amd64 (20190805) PackageArchitecture: all ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: sbuild-launchpad-chroot UpgradeStatus: Upgraded to focal on 2020-04-17 (725 days ago) modified.conffile..etc.schroot.setup.d.90apt-sources: [modified] mtime.conffile..etc.schroot.setup.d.90apt-sources: 2022-04-12T15:23:14.405987 ** Affects: sbuild-launchpad-chroot (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1968782 Title: CHROOT_SESSION_PURGE is set to false without union-type, so 90apt- sources does not render To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sbuild-launchpad-chroot/+bug/1968782/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
