About Me

I have performed the following steps for this PPA:

PPA Contents

This PPA is operational for the Ubuntu distribution lunar (23.04) only. All packages (with some exceptions) have been built and tested for this specific environment on x86_64 architectures.

Those source packages come only from official sources such as:

    + https://launchpad.net/ubuntu/+source
    + https://packages.debian.org/source
    + upstream git repositories usually hosted on https://github.com or https://gitlab.com

Any source package listed in the links below is built, tested (during the build process) & its binary packages uploaded into this PPA only when its version is fresher than what is available at that time for the corresponding binaries on the official Ubuntu repositories of the latest stable distribution. This means that this PPA does not mirror the official Ubuntu repositories of the latest distribution, but rather enhances them with more recent releases.

All the built binary packages currently available are listed per source package and version here. They can be divided into the following collections:

Build Tools

All the packages available in this PPA are built with the following tools, with a top-down priority list:

  1. gbp buildpackage: when the source git repository offers a correctly maintained pristine-tar or upstream branch. The packages version numbers are not modified.
  2. debuild: when the sources offer a debian folder. The packages version numbers end with +23.04.
  3. fpm/checkinstall: all other cases. The packages version numbers end with -23.04.

Unstable Packages Name Format

The unstable packages which appear in the unstable component of the PPA have different name formats to distinguish them from previous stable releases, for those who accept to live closer to the edge. You can be confident that they have passed a minimal testing. Some of them solve some issues discovered in previous stable versions. You can also always go back to the previous stable package if necessary. The name formats differ depending on the tool used to build them:

  • built with debuild:
    <package_name>_<unstable_release_number>~git<commit_date>.<short_hash_id>+23.04_amd64.deb
  • built with fpm/checkinstall: 
    <package_name>_<unstable_release_number>~git<commit_date>.<short_hash_id>-23.04_amd64.deb
    <package_name>_<git describe --tags>-23.04_amd64.deb

Upgrading Safely From an Ubuntu Release to Another One

In order to avoid any issue during the distribution upgrade process, I suggest that you perform the following tasks prior to the distribution upgrade: (replace for instance <new_os_release_number> with 23.04; <previous_os_release_number> with 22.10; <new_os_code_name> with lunar; <previous_os_code_name> with kinetic)

  • reload all packages information: sudo apt update
  • upgrade your packages: sudo apt upgrade
  • backup your whole system:
    • from another system such as a USB flash drive: fsarchiver should come in handy
    • or with a LVM snapshot
    • or with a Btrfs snapshot
    • ...
  • reboot if necessary
  • comment out all third-party PPA components in /etc/apt/sources.list.d/*.list
  • close all the applications windows
  • from a previous stable release to the latest stable release:
    • on a server with a desktop environment: press Alt+F2 and type update-manager -c into the command box
    • Update Manager should open up and tell you that Ubuntu <new_os_release_number> is now available.
    • If not you can run /usr/lib/ubuntu-release-upgrader/check-new-release-gtk
    • Click Upgrade and follow the on-screen instructions.
    • on a headless server: do-release-upgrade.
  • from the latest stable release to the latest development release:
    • Install ubuntu-release-upgrader-core if it is not already installed.
    • Launch the upgrade tool with the command sudo do-release-upgrade --devel-release
    • Follow the on-screen instructions.
  • from the previous development release to the latest development release:
    sudo sed -i "s/<previous_os_code_name>/<new_os_code_name>/g" /etc/apt/sources.list
    sudo apt update; sudo apt upgrade
  • once the upgrade process is done, reselect and upgrade the distribution/release name of all third-party PPAs (for instance from kinetic to lunar for those which are up-to-date) in /etc/apt/sources.list.d
  • reload package information and upgrade all updated packages: sudo apt update; sudo apt upgrade
  • make sure that the packages which have been built for the previous Ubuntu release have been upgraded: 
    sudo apt list --installed | grep -P -- "\+<previous_os_release_number>"
    sudo apt list --installed | grep -P -- "-<previous_os_release_number>"
  • for those which have not been upgraded (all those listed in the 2 previous commands), you may downgrade them to the latest version available from the Ubuntu archive or wait until a new version is available from this PPA. Cf. Downgrading Packages
  • check how the distribution upgrade performed by reading the logs in /var/log/dist-upgrade and solve all remaining issues:
    • reinstall all necessary packages which have been removed and listed in history.log in the Remove: paragraph.
    • reinstall all necessary packages which could not be installed due to errors and listed in apt.log and apt-term.log
  • reboot when done

Downgrading Packages

If necessary, it is of course possible to downgrade the packages installed from this PPA to the ones available in the official repositories.

In order to automate this process for all installed packages, the following bash scripts are provided:

  • apt-downgrade-bin-packages-to-official-archive.sh:
    • downgrading some (light mode) or all (full mode) installed binary packages with a version ending with +<os_version> or -<os_version> to the package version provided by the official Ubuntu repositories.
    • please consult the help (-h) for details, especially regarding the differences between both modes.
    • it is possible to pass perl regular expressions to narrow the search for installed binary packages which need to be downgraded.
  • apt-downgrade-src-package-to-official-archive.sh:
    • downgrading all installed binary packages listed from a source package with a version ending with +<os_version> or -<os_version> to the package version provided by the official Ubuntu repositories.
    • please consult the help (-h) for details.
  • apt-update-perl-bin-packages-to-official-archive.sh:
    • this script allows to update all perl installed binary packages with a version ending with + to the package version provided by the official Ubuntu repositories.
    • please consult the help (-h) for details, especially regarding the differences between both <auto> modes.
  • apt-update-python-bin-packages-to-official-archive.sh:
    • this script allows to update all python installed binary packages with a version ending with + to the package version provided by the official Ubuntu repositories.
    • please consult the help (-h) for details, especially regarding the differences between both <auto> modes.
  • dpkg-lock.sh: dpkg semaphore used in previous scripts.

Removing Obsolete Packages

Packages which have no installation candidate can be removed/purged with the help of a script:

  • apt-remove-obsolete-bin-packages.sh:
    • removing/purging all obsolete installed binary packages, i.e. all packages which have no installation candidate.
    • it is possible to pass perl regular expressions to narrow the search for installed binary packages which need to be removed.
    • please consult the help (-h) for details, especially regarding the differences between both <auto> modes.

Removing Orphaned Packages

Packages among libs, oldlibs and introspection sections that have no packages depending on them can be removed/purged with the help of a script:

  • apt-remove-orphaned-bin-packages.sh:
    • removing/purging all orphaned installed binary packages, i.e. all packages among libs, oldlibs and introspection sections that have no packages depending on them.
    • it is possible to pass perl regular expressions to narrow the search for installed binary packages which need to be removed.
    • please consult the help (-h) for details, especially regarding the differences between both <auto> modes.

Reinstalling Installed packages

All installed packages which have an installation candidate can be reinstalled with the help of a script:

  • apt-reinstall-bin-packages.sh:
    • reinstalling all installed binary packages, i.e. all packages which have an installation candidate.
    • it is possible to pass a perl regular expression to narrow the search for installed binary packages which need to be reinstalled.
    • no manual user's consent will be asked before each package reinstallation.

Known Error Messages And Workaround

If you encounter the following error messages during sudo apt update, it means that the PPA is currently being refreshed with new releases; this process happens relatively often, mostly potentially during week-ends and every week day between ~ 6 am and 1 pm CET:

  • "Failed to fetch https://git.sdxlive.com/PPA/plain/Ubuntu/dists/lunar/InRelease Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?) Some index files failed to download. They have been ignored, or old ones used instead."
  • "Packages
    • Hash Sum mismatch
    • Hashes of expected file:
    • ...
    • Hashes of received file:
    • ..."

In order to avoid any issue about index files not being synced during the PPA maintenance, the visiblity of the PPA repository is now private when the index files are being updated with new package(s) and back to public when the update is done. During that very short time frame, accessing the repository is not possible anymore and you get one of the error messages described above.

Just wait to be outside the refresh time frame so that the PPA index has been completely updated and retry your sudo apt update and sudo apt upgrade or sudo apt --show-progress install <package>.
