Multistrap and Secure Apt
[ Multistrap overview ] [ Secure Apt ] [ Example configurations ] [ Using multistrap for pbuilder chroots ] [ Multiple repositories ] [ Cascading configuration ] [ Cross building support ] [ Multistrap Wiki page ]
To use authenticated apt repositories, multistrap either needs to be able to install an appropriate keyring package from the existing apt sources outside the multistrap environment or have the relevant keys already configured using apt-key on the host system.
If relevant packages exist, specify them in the keyring option for each repository. multistrap will then check that apt has already installed this package so that the repository can be authenticated before any packages are downloaded from it.
Note that all repositories to be used with multistrap must be authenticated or apt will fail. Similarly, secure apt can only be disabled for all repositories (by using the --no-auth command line option or setting the general noauth option in the configuration file), even if only one repository does not have a suitable keyring available. Not all packages need keyring packages, if you configure apt-key appropriately.
The keyring package(s) will also be installed inside the multistrap environment to match the installed apt sources for the multistrap.
All configuration of apt-key needs to be done for the machine running multistrap itself.
