  • pbuilder root seems to lack support for usrmerge when doing autopkgtest

    From Andreas Tille@21:1/5 to All on Tue Sep 19 16:40:02 2023
    Hi,

    I configured pbuilder (Uploaders in CC) to run autopkgtest after a
    successful build. This worked nicely until yesterday (at least - may be
    a couple of days before but I did not noticed). Since yesterday I get:

    E: /bin resolved to a different inode than /usr/bin
    E: Unmerged usr is no longer supported, install usrmerge to continue. autopkgtest: WARNING: Test dependencies are unsatisfiable - calling apt install on test deps directly for further data about failing dependencies in test logs

    The test itself runs in Salsa CI - so the package itself is not broken.
    I'm actually using cowbuilder - but I naively assume this is not
    relevant.

    I tried to fix this with

    diff --git a/pbuilderrc b/pbuilderrc
    index d796fd8..9176073 100644
    --- a/pbuilderrc
    +++ b/pbuilderrc
    @@ -11,6 +11,6 @@ OTHERMIRROR="deb [trusted=yes] file:///var/cache/pbuilder/extra/release ./"

    # this is necessary for running ''apt-ftparchive'' in the hook below -EXTRAPACKAGES="apt-utils"
    +EXTRAPACKAGES="apt-utils usrmerge"


    in /etc but with no change. According to the log the package usrmerge
    is really installed in the pbuilder chroot.

    Do you have any hints? If not, what further information should I
    provide? (logs etc?)

    Kind regards
    Andreas.

    That's from apt:

    apt (2.7.4) unstable; urgency=medium
    …
    * Only accept installs of usrmerge on unmerged-usr systems.
    As of bookworm, merged-usr is mandatory, and people got caught
    in the crosshairs of the dpkg fsys-unmessusr debacle and inadvertently
    reverted back to an unmerged configuration and continue to remain
    on an unsupported system unknowingly.

    Looks like your chroot is not /usr-merged; no idea why installing the usrmerge package didn't and doesn't change it.

    Do you have any hints? If not, what further information should I
    provide? (logs etc?)

    Just for comparison my (unstable) chroot looks /usr-merged:

    % ll /var/cache/pbuilder/base.cow
    lrwxrwxrwx 2 root root 7 Sep 18 2022 bin -> usr/bin
    …

    (Looking through my other chroots, it looks like only the unstable
    and the experimental ones are merged, in the others, including the
    testing ones, /bin is still a directory. Interesting.)

    Maybe try to login in:
    cowbuilder --login --save-after-login [--basepath /some/where]
    and reconfigure usrmerge, or something?


    Cheers,
    gregor

    Haha, upgrading a trixie chroot shows:

    Preparing to unpack .../usr-is-merged_37_all.deb ...
    W: /etc/unsupported-skip-usrmerge-conversion exists.
    Unpacking usr-is-merged (37) over (35) ...


    Might have been created via debootstrap's "--variant=buildd" option
    in the past …

    OK.

    lrwxrwxrwx 2 root root 7 Sep 18 2022 bin -> usr/bin
    …

    I confirm that /var/cache/pbuilder/base.cow/bin was no symlink but
    just the old /bin dir.

    Maybe try to login in:
    cowbuilder --login --save-after-login [--basepath /some/where]
    and reconfigure usrmerge, or something?

    I did so and usrmerge was installed but somehow it seems it was not
    doing its job.

    I simply created a new chroot via

    sudo cowbuilder --create

    and it works now. So may be this thread is simply some warning that
    usrmerge might fail.

    Kind regards
    Andreas.
