User’s Manual¶
The user’s manual covers using a mini-buildd installation – i.e., everything you can do with it given someone else had already set it up for you as a service.
Introduction¶
The core functionalities of mini-buildd are, 1st the arch-multiplexed clean building, and 2nd providing a repository. You don’t need to worry about 1st, mini-buildd just does it for you.
The 2nd however, the repository, goes public and hits “global Debian namespace”; so, as a big picture, it’s important first to understand how mini-buildd’s (default) setup tries to deal with this.
First of all, each instance has it’s own identity
string, which will be used in the name of the keyring package,
and will also appear in the apt repository in the Origin
field.
Second, each instance instance may have N
repositories,
which each have their own identity string, which determines
the actual distribution names (CODENAME-ID-SUITE
) to be used
for uploads or in apt lines.
Both identities should be “globally unique” to avoid any confusion or conflicts with other existing repositories.
Note
Exceptions are the generic Sandbox and Developer
repositories, with the de-facto standard names
test
and debdev
; these should never be used
publicly or for anything but testing.
Third, when people are mixing repositories together, we want to avoid package clashes, like same PACKAGE-VERSION from two different repositories. Also, we want guaranteed upgradeability between two different base distributions, and from experimental to non-experimental suites. Hence, at least in the Default Layout, we also have a version restriction, which resembles that of Debian Backports:
The Default Layout’s Suites and Semantics Overview | |||||
---|---|---|---|---|---|
Suite | Flags | Version restriction | Repository | Semantic | Consumer |
experimental | U E 6R | ~ID+0 |
No auto | Use at will | Developer. |
snapshot | U E 12R | ~ID+0 |
No auto, but upgrades | Continuous integration | Developer, beta tester. |
unstable |
U M 9R | ~ID+[1-9] |
No auto, but upgrades | Proposed for live | Developer, beta tester. |
testing |
M 3R | ~ID+[1-9] |
No auto, but upgrades | QA testing | Quality Assurance. |
stable |

No auto, but upgrades | Live | End customer. |

User Setup¶
As a minimal setup, you should have a web browser installed; you can instantly browse mini-buildd, and use all functionality that do not require extra permissions.
To be able use advanced functionality (for example, create package subscriptions, access restricted API calls, or upload your GnuPG public key), create a user account:
- Register a user account.
- Setup your profile (package subscriptions, GnuPG key upload).
To access mini-buildd from the command line via
mini-buildd-tool
, install python-mini-buildd
:
# apt-get install python-mini-buildd
To upload packages, install dput
and add mini-buildd’s
dput config to your
~/.dput.cf
:
# apt-get install dput
? mini-buildd-tool HOST getdputconf >>~/.dput.cf
Note
After ~/.dput.cf
has been set up this way, you can
use [USER@]ID
-like shortcuts instead of HOST
,
and these will also appear in the bash auto-completion
of mini-buildd-tool
.
Using the repository¶
Upload a package¶
Changelog Magic Lines (per-upload control)¶
mini-buildd
currently supports these so called magic
lines
as changelog entry to control it on a per-upload basis:
MINI_BUILDD: BACKPORT_MODE
Make QA-Checks that usually break when backporting unlethal (like lintian).
MINI_BUILDD: AUTO_BACKPORTS: CODENAME-REPOID-SUITE[,CODENAME-REPOID-SUITE...]
After successful build for the upload distribution, create and upload automatic internal ports for the given distributions.
FAQ¶
Todo
BUG: reprepro fails with debian/ as symlink in Debian native packages
Please follow [4] for this subject.
In such a case, builds will be fine, but reprepro will not be
able to install the package; you will only be able to see
reprepro’s error “No section and no priority for” in the
daemon.log
.
For the moment, just avoid such a setup (which is imho not desireable anyway). However, as it’s a legal setup afaik it should work after all.
Using the API¶
Repository maintenance¶

IDEA: Dependency check on package migration.
Todo
IDEA: Custom hooks (prebuild.d source.changes, preinstall.d/arch.changes, postinstall.d/arch.changes).
FAQ¶
Todo
FAQ: aptitude GUI does not show distribution or origin of packages
To show the distribution of packages, just add %t
to
the package display format [1]. For example, I
do prefer this setting for the Package-Display-Format:
aptitude::UI::Package-Display-Format "%c%a%M%S %p %t %i %Z %v# %V#";
The origin cannot be shown in the package display format [2]. However, you may change the grouping to categorize with “origin”. For example, I do prefer this setting for the Default-Grouping:
aptitude::UI::Default-Grouping "task,status,pattern(~S~i~O, ?true ||),pattern(~S~i~A, ?true ||),section(subdirs,passthrough),section(topdir)";
This will group installed packages into an Origin->Archive hierarchy.
Additionally to aptitude’s default “Obsolete and locally installed” top level category (which only shows packages not in any apt archive), this grouping also more conveniently shows installed package _versions_ which are not currently in any repository (check “Installed Packages/now”).

BUG: apt secure problems after initial (unauthorized) install of the archive-key package
- aptitude always shows <NULL> archive
You can verify this problem via:
# aptitude -v show YOURID-archive-keyring | grep ^Archive
Archive: <NULL>, now
- BADSIG when verifying the archive keyring package’s signature
Both might be variants of [3] (known to occur for <= squeeze). For both, check if this:
# rm -rf /var/lib/apt/lists/*
# apt-get update
fixes it.

FAQ: Multiple versions of packages in one distribution
This is not really a problem, but a uncommon situation that may lead to confusion.
Generally, reprepro does allow exactly only one version of a package in a distribution; the only exception is when installed in different components (e.g., main vs. non-free).
This usually happens when the ‘Section’ changes in the corresponding ‘debian/control’ file of the source package, or if packages were installed manually using “-C” with reprepro.
Check with the “show” command if this is the case, i.e., s.th. like:
$ mini-buildd-tool show my-package
you may see multiple entries for one distribution with different components.
mini-buildd handles this gracefully; the remove
,
migrate
and port
API calls all include an optional
‘version’ parameter to be able to select a specific version.
In the automated rollback handling, all versions of a source package are shifted.
