This directory contains my scripts to build backports of R software from Debian sid to older Debian distributions. Currently I am using the following setup: ~/.pbuilderrc contains: NAME="$DIST-$ARCH" APTCACHEHARDLINK=yes DISTRIBUTION="$DIST" DEBOOTSTRAPOPTS=("--arch" "$ARCH" "--keyring=/usr/share/keyrings/debian-archive-keyring.gpg" "${DEBOOTSTRAPOPTS[@]}") BASETGZ="`dirname $BASETGZ`/$NAME-base.tgz" BUILDRESULT="/var/cache/pbuilder/$NAME/result/" APTCACHE="/var/cache/pbuilder/$NAME/aptcache/" MIRRORSITE="http://ftp.de.debian.org/debian/" OTHERMIRROR="deb http://security.debian.org $DIST/updates main|deb http://localhost/r-cran $DIST-cran34/" COMPONENTS="main" This means I have the appropriate aptcache and buildresult directories set up under /var/cache/pbuilder. I have several pbuilder images used for package creation under /var/cache/pbuilder, among others: /var/cache/pbuilder/jessie-i386-base.tgz With the pbuilderrc mentioned above, this can be created as a normal user with export ARCH=i386 export DIST=jessie sudo -E pbuilder create Then, using sudo -E pbuilder login --save-after-login these have a standard Debian mirror, the security sources setup in their /etc/apt/sources.list, as well as my local http package source where the r-base package build results are available. I have also imported the apt key of my repository inside the pbuilder chroots. For some reason, the keyring option to debootstrap is not used (necessary on Ubuntu) so I needed to pass this on the commandline when building the pbuilder chroot for wheezy-i386. When using these scripts on Debian, I used to configure sudo to allow my normal user to use pbuilder, apt-get and the backporting scripts. Currently, I have set up my jessie installation using the Ubuntu like sudo configuration that I selected during the original installation of wheezy. I am building other architectures on different machines (raspi: armxx) or in a local chroot (amd64).
