All bugs of some higher severities are by default considered release-critical; currently, these are critical, grave and serious bugs.
Such bugs are presumed to have an impact on the chances that the package
will be released with the stable release of Debian: in general, if a package
has open release-critical bugs filed on it, it won't get into
consequently won't be released in
testing bug count are all release-critical bugs which
are marked to apply to package/version combinations
that are available in
testingfor a release architecture.

The structure of the distribution archives is such that they can only
contain one version of a package; a package is defined by its name. So, when
the source package acmefoo is installed into
testing, along with
its binary packages acme-foo-bin, acme-bar-bin,
libacme-foo1 and libacme-foo-dev, the old version is
However, the old version may have provided a binary package with an old soname of a library, such as libacme-foo0. Removing the old acmefoo will remove libacme-foo0, which will break any packages which depend on it.
Evidently, this mainly affects packages which provide changing sets of binary packages in different versions (in turn, mainly libraries). However, it will also affect packages upon which versioned dependencies have been declared of the ==, <= or << varieties.
When the set of binary packages provided by a source package change in
this way, all the packages that depended on the old binaries will have to be
updated to depend on the new binaries instead. Because installing such a
source package into
testing breaks all the packages that depended on it in
testing, some care now has to be taken: all the depending packages must be
updated and ready to be installed themselves so that they won't be broken,
and, once everything is ready, manual intervention by the release manager or
an assistant is normally required.
If you are having problems with complicated groups of packages like this, contact debian-devel or debian-release for help.
I still don't understand! The
testing scripts say that this
package is a valid candidate, but it still hasn't gone into
testingscripts say that this package is a valid candidate, but it still hasn't gone into
This tends to happen when in some way, directly or indirectly, installing the package will break some other package.
Remember to consider your package's dependencies. Suppose your package
depends on libtool, or libltdlX. Your package won't go into
testing until the right version of libtool is ready to go in with it.
In turn, that won't happen until installing libtool doesn't break things
testing. In other words, until all other packages which depend
on libltdlY (where Y is the earlier version) have been
recompiled, and all their release critical bugs are gone, etc, none of these
packages will enter
This is where the textual output
is useful: it gives hints (albeit very terse ones) as to which packages
break when a valid candidate is added to
testing (see the Developer's Reference for more details).
Why is it sometimes hard to get Architecture: all packages
If the Architecture: all package is to be installed, it must be possible to satisfy its dependencies on all architectures. If it depends on certain packages which only compile on a limited set of Debian's architectures, then it can't do that.
However, for the time being,
testing will ignore Architecture:
all packages' installability on non-i386 architectures. (
gross hack and I'm not really happy to have made it, but there you go.

Check the status of your package in the build log database. If the package doesn't build, it will be marked as failed; investigate the build logs and fix any of the problems that are caused by your package's sources.
If you happen to notice that some architectures have built the new
version of your package, but it isn't showing up in
testing scripts output,
then you just have to be a bit more patient until the respective buildd
maintainer uploads the files to the Debian archive.
If you notice that some architectures haven't built your new version of the package at all, despite the fact you uploaded a fix for an earlier failure, the reason is probably that it's marked as waiting for dependencies (Dep-Wait). You can also see the list of these so-called wanna-build states to make sure.
These problems usually get fixed eventually, but if you've been waiting for a longer period of time (say, two weeks or more), notify the respective port buildd maintainer if such an address is documented on the port web page, or the mailing list of the port.
If you have explicitly dropped the architecture from the Architecture list
in the control file, and the package has been built for that architecture
before, you will need to request that the old binary package for this
architecture be removed from the archive before your package can transition to
testing. You need to file a bug against
ftp.debian.org requesting removal of
the dropped architecture's packages from the unstable archive. Generally the
relevant porting list should be informed as a matter of courtesy.
Are there any exceptions? I'm sure acmefoo has just made
testing despite not satisfying all of the requirements.
testingdespite not satisfying all of the requirements.
The release manager can override the rules in two ways:
- They can decide that the breakage caused by the installation of a new library will make things better rather than worse, and let it go in along with its flotilla of dependents.
- They can also manually remove packages from
testingthat would be broken, so that new stuff can be installed.
실제적이고, 간단하지 않은 예를 제공할 수 있나요?
Here's one: when the source package apache is installed into
testing, along with its binary packages apache,
apache-common, apache-dev and apache-doc, the
old version is removed.
However, all Apache module packages depend on
something), apache-common (<< something),
so this change breaks all of those dependencies. Consequently, all Apache
modules need to be recompiled against the new version of Apache in order
testing to be updated.
Let's elaborate on this a bit further: after all of the modules have been
updated in unstable to work with a new Apache, the
testing scripts try
apache-common and find out that it breaks all the Apache modules
because they have
Depends: apache-common (<< the current
version), and then try libapache-foo to find
out that it doesn't install because it has
Depends: apache-common (>=
the new version).
However, later they'll apply a different logic (sometimes prompted by a manual intervention): they'll ignore the fact apache-common breaks stuff, and keep going with things that work; if it still doesn't work after we've done everything we can, too bad, but maybe it will work. Later they'll try all the random libapache-foo packages and see that they indeed work.
After everything's been tried, they check how many packages have been
broken, work out if that's better or worse than what there was originally
and either accept everything or forget about it. You'll see this in
recur: [foo bar] baz
having already found that foo and
bar make things better, I'm now trying baz to
see what happens, even though that breaks things. The lines of
update_output.txt that start with
things that appear to make things better, and
update_output.txt 파일은 읽을 수 없습니다!
그건 질문이 아닙니다. ;-)

Note that the architectures are checked in alphabetical order and only the
problems on the first architecture with problems are shown — that's why
the alpha architecture is shown so often.
got line includes the number of problems in
testing on the
different architectures (until the first architecture where a problem is
found — see above). The
i-45 means that if cln would go into
testing, there would be 45 uninstallable packages on i386. Some of the
entries above and below cln show there were 43 uninstallable
testing on i386 at the time.
skipped: cln (0) (150+4) line means that there are still 150
packages to go through after this package until this check of all packages
is completed, and that 4 packages have been found already that won't be
planned to be upgraded because they would break dependencies. The

The following pages provide additional information about the current state of testing and the migration of packages from unstable to testing:
- Statistics on binary packages that are out of date for testing, stable
- Dependency problems in testing, stable
- Nice web front-end to help you find out why packages are being held out of testing
You might be interested in reading an older explanation email. Its only major flaw is that it doesn't take the package pool into account, because that was implemented by James Troup after it was written.
The testing code is available from ftp-master.
Anthony Towns takes credit for the implementation of testing.
