This is the package archive system for UBports projects. It hosts various PPAs containing all deb-components of Ubuntu Touch. New PPAs can be created dynamically by the CI server using a special git-branch naming convention.
The name of the branch translates literally to the name of the PPA:
Non-standard PPAs (i.e. not
bionic) are kept for three months. In case they need to be kept for a longer time, a file with the name
ubports.keep can be created in the root of the repository, containing the date until which the PPA shall be kept open in the form of YYYY-MM-dd. If this file is empty, the PPA will be kept for two years after the last build.
