Package: apt
Version: 1.0.1
Severity: normal
Tags: moreinfo
User: helmutg@debian.org
Usertags: rebootstrap
Dear apt maintainers,
In a particular circumstance I arrive at a situation where apt's cache
appears to be subtly wrong. The immediate observation is:
# apt-get check
Reading package lists...
Building dependency tree...
Reading state information...
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
libatomic1:m68k : PreDepends: multiarch-support:m68k but it is not installable
libgcc2:m68k : PreDepends: multiarch-support:m68k but it is not installable
libgomp1:m68k : PreDepends: multiarch-support:m68k but it is not installable
libstdc++6:m68k : PreDepends: multiarch-support:m68k but it is not installable
E: Unmet dependencies. Try using -f.
#
If I then issue apt-get --no-download update and run apt-get check
again, no error is reported. I would not have expected a run of apt-get
update to be able to correct a dependency problem and therefore conclude
a bug in apt.
Now describing the circumstances in which this happens has proven to be
hard. It is reproducible very reliably: Jenkins runs into it in every
rebootstrap build.
https://jenkins.debian.net/job/rebootstrap_arm64_gcc49/9/console
Having to wait 5 hours for a reproducer is a bad thing though, which is
why I tag this bug as moreinfo. The basic sequence of the rebootstrap
job (from the point of view of apt) is:
* debootstrap a sid chroot and run everything in there.
* Run apt-get update once and never again (without --no-download).
* dpkg --add-architecture $some_arch
* Iteratively change packages using operations:
* apt-get install -y ... # build-depends
* apt-get remove -y ... # build-conflicts
* dpkg -i *.deb # results from some dpkg-buildpackage
Among other things this causes the foreign libc and foreign gcc
libraries to replaced with differently staged packages of the same
version. After installing gcc stage2 and eglibc stage2, apt-get check
thinks that everything is fine. Once installing the gcc stage3, the
above errors show up (and are "healed" by apt-get --no-download update).
This is a summary of the current diagnosis of this issue and its main
goal is to obtain a bug number to reference the issue from elsewhere.

[ David Kalnischkies ]
* [API Break] change "std::string pkgAcquire::Item::DescURI()" to
"std::string pkgAcquire::Item::DescURI() const"
* [ABI-Break] increase hashtable size for packages/groups by factor 5
* [ABI-Break] cleanup datatypes mix used in binary cache
* [internal API-Break] remove the Section member from package struct
* use 'best' hash for source authentication (LP: 1098738)
* use HashStringList in the acquire system
* deal with hashes in ftparchive more dynamic as well
* reenable pipelining via hashsum reordering support
* parse and retrieve multiple Descriptions in one record
* improve pkgTagSection scanning and parsing

.
[ Michael Vogt ]
* add support for "apt-get build-dep foo.dsc"
* add support for "apt-get build-dep unpacked-source-dir"
* add support for "apt-get install foo_1.0_all.deb"
* make "apt-get update" progress much more accurate by loading the
sizes of the targets into the fetcher early
* Implement simple by-hash for apt update to improve reliability of
the update. Apt will try to fetch the Packages file via
/by-hash/$hash_type/$hash_value if the repo supports that.

- add Acquire-By-Hash=1 to Release file
* add Debug::Acquire::Progress debug option

pkgAcqIndex{,Merge}Diffs
* [internal API-Break] rename pkgCache::Package::NextPackage to
pkgCache::Package::Next
* Calculate Percent as part of pkgAcquireStatus to provide a weighted
percent for both items and bytes
* apt-pkg/contrib/macros.h: bump library version to 4.13
* apt-private/acqprogress.cc: do not show file size on IMSHit, it wasn't
fetched
* Fix warnings from clang -Wall/clang -fsanitize=address
* add DropPrivs() and drop privileges to nobody when running the
the buildin apt and dump solvers
* lp:~mvo/apt/webserver-simulate-broken-with-fix346386:
