NAME

   add-apt-repository  -  Adds a repository into the /etc/apt/sources.list
   or /etc/apt/sources.list.d or removes an existing one

SYNOPSIS

   add-apt-repository [OPTIONS] REPOSITORY

DESCRIPTION

add-apt-repository is a script which adds an external APT repository to
either /etc/apt/sources.list or a file in /etc/apt/sources.list.d/ or
removes an already existing repository.

   The options supported by add-apt-repository are:

   -h, --help Show help message and exit

   -m, --massive-debug Print a lot of debug  information  to  the  command
   line

   -r, --remove Remove the specified repository

   -y, --yes Assume yes to all queries

   -k, --keyserver Use a custom keyserver URL instead of the default

   -s,  --enable-source  Allow downloading of the source packages from the
   repository

REPOSITORY STRING

   REPOSITORY can  be  either  a  line  that  can  be  added  directly  to
   sources.list(5),  in the form ppa:<user>/<ppa-name> for adding Personal
   Package Archives, or a distribution component to enable.

   In  the   first   form,   REPOSITORY   will   just   be   appended   to
   /etc/apt/sources.list.

   In  the second form, ppa:<user>/<ppa-name> will be expanded to the full
   deb  line  of  the  PPA  and   added   into   a   new   file   in   the
   /etc/apt/sources.list.d/  directory.   The  GPG public key of the newly
   added PPA will also be downloaded and added to apt's keyring.

   In the third form, the given distribution component will be enabled for
   all sources.
