• Args = <Script> <Stage> <Version> <Changelog file> <Source tar>

• Generates a change log from the passed in changelog file and copies it in to debian/changelog
• Wrapped by changelog_template
• Make sure to check debian/changelog after generating

${FEXPPA}/create_packages.py 0 ${FEX_VERSION} ${PACKAGE_VERSION} TestChanges fex-emu_${PACKAGE_VERSION}.orig.tar.gz

• Generates all the target specific folder structures for building source packages
• Generates in to gen_ppa in cwd

${FEXPPA}/create_packages.py 1 ${FEX_VERSION} ${PACKAGE_VERSION} TestChanges fex-emu_${PACKAGE_VERSION}.orig.tar.gz

• Walks all of the target specific debian trees and runs debuild -S over them cleanly

${FEXPPA}/create_packages.py 2 ${FEX_VERSION} ${PACKAGE_VERSION} TestChanges fex-emu_${PACKAGE_VERSION}.orig.tar.gz

• Walks all of the created debian packages and uploads them directly to the fex-ppa with dput
• Hardcoded to ppa:fex-emu/fex

This allows you to create a pbuilder to test building the package before uploading to PPA

• Depending on which builder you want, generate an image for whichever distro series

sudo pbuilder create --distribution focal --architecture amd64 --basetgz /var/cache/pbuilder/focal-amd64-base.tgz

sudo pbuilder create --distribution jammy --architecture amd64 --basetgz /var/cache/pbuilder/jammy-amd64-base.tgz

sudo pbuilder create --distribution kinetic --architecture amd64 --basetgz /var/cache/pbuilder/kinetic-amd64-base.tgz

sudo pbuilder create --distribution focal --architecture arm64 --mirror "http://ports.ubuntu.com/ubuntu-ports/" --basetgz /var/cache/pbuilder/focal-arm64-base.tgz

sudo pbuilder create --distribution jammy --architecture arm64 --mirror "http://ports.ubuntu.com/ubuntu-ports/" --basetgz /var/cache/pbuilder/jammy-arm64-base.tgz

sudo pbuilder create --distribution kinetic --architecture arm64 --mirror "http://ports.ubuntu.com/ubuntu-ports/" --basetgz /var/cache/pbuilder/kinetic-arm64-base.tgz

This will attempt building the package provided with the dsc file. Result will be in /var/cache/pbuilder/result/

sudo pbuilder build --distribution focal --architecture amd64 --basetgz /var/cache/pbuilder/focal-amd64-base.tgz ../fex-emu_$FEX_VERSION.dsc

sudo pbuilder build --distribution jammy --architecture amd64 --basetgz /var/cache/pbuilder/jammy-amd64-base.tgz ../fex-emu_$FEX_VERSION.dsc

sudo pbuilder build --distribution kinetic --architecture amd64 --basetgz /var/cache/pbuilder/kinetic-amd64-base.tgz gen_ppa/fex-emu-armv8.0_${PACKAGE_VERSION}~k.dsc

sudo pbuilder build --distribution focal --architecture arm64 --basetgz /var/cache/pbuilder/focal-arm64-base.tgz gen_ppa/fex-emu-armv8.0_${PACKAGE_VERSION}~f.dsc

sudo pbuilder build --distribution jammy --architecture arm64 --basetgz /var/cache/pbuilder/jammy-arm64-base.tgz gen_ppa/fex-emu-armv8.0_${PACKAGE_VERSION}~j.dsc

sudo pbuilder build --distribution kinetic --architecture arm64 --basetgz /var/cache/pbuilder/kinetic-arm64-base.tgz gen_ppa/fex-emu-armv8.0_${PACKAGE_VERSION}~k.dsc

sudo rm /var/cache/pbuilder/impish-amd64-base.tgz

• Typically stage three of the create_packages.py script does this dput ppa:fex-emu/fex ../fex-emu_2201_source.changes

• debuild -S would have printed some text about this

  • Working: dpkg-buildpackage: info: full upload (original source is included)
  • Non-working: dpkg-buildpackage: info: binary and diff upload (original source NOT included)

• Failure I found with this was changelog had multiple version back to back same versions

• Changes need to be indented by two spaces otherwise the change file is invalid.
• Ensure it is indented

• Add auto-expand-secmem to $HOME/.gnupg/gpg-agent.conf and then restart gpg-agent with killall gpg-agent
• Lets GPG agent allocate more secure working memory which is necessary to allow multiple signing agents at once

When updating the package with a new subversion, the old version first needs to be deleted from the ppa.

• This is due to their version check not really understanding the <Version>~<SubVersion>~<distro series> layout
