Qt >= 5.15 apps: linphone (4.2.5), nheko (0.10.2), qbittorrent (4.6.5)

This PPA also requires compatible KDE 5.80.x backports for any system that has KDE-based software installed. So make sure to read the notes at the KDE 5.80 PPA for latest info about the KDE backports before proceeeding:


Note (21 Aug 2021): If any dependencies are missing after adding the PPAs described in the install instructions below then make sure to inform me so that the dependencies can be copied here or to the KDE PPA as appropriate.

*** Install ***

NOTES FOR ALL: Upgrading the system Qt stack is a major system change as a lot of highly used software depends on Qt (ie. digiKam as one example) and the KDE stack must also be upgraded to a newer version (>= 5.80.0) that is compatible with newer Qt 5.15.x software. So remember to do a full backup first, same as before any such major upgrade! All these PPAs are required for full functionality and installation of the backported Qt/KDE packages:

  sudo add-apt-repository ppa:savoury1/qt-5-15
  sudo add-apt-repository ppa:savoury1/kde-5-80
  sudo add-apt-repository ppa:savoury1/gpg
  sudo add-apt-repository ppa:savoury1/ffmpeg4

Also, the VLC 3 PPA is a requirement for Xenial to install Phonon backend for VLC (requires >= 3.0), and recommended for all series. Add like this:

  sudo add-apt-repository ppa:savoury1/vlc3

Note for Focal: Core Qt 4 packages of qt4-x11 and qtwebkit are built here allowing Qt 4 (not KDE 4) applications to run on the current latest LTS.

Notes for Xenial & Bionic: All qt*-opensource-src packages here are built with GCC 9.3.0 and also against ppa:savoury1/display with latest display stack upgrades. These Qt upgrades then require GCC 9.3.0 and the latest display stack to install and run, so add these two PPAs with the commands:

  sudo add-apt-repository ppa:savoury1/gcc-9
  sudo add-apt-repository ppa:savoury1/display

Notes for Xenial: Some required Qt packages are at ppa:savoury1/qt-xenial which has backports of the Qt 4 & 5 stacks from Bionic. The matching KDE stack from Bionic is also required for proper Qt 4 & KDE 4 support. Also, backported APT/GTK from Bionic is needed for some Qt/KDE backports. So add these four commands at the top of the above list of commands for install:

  sudo add-apt-repository ppa:savoury1/apt-xenial
  sudo add-apt-repository ppa:savoury1/gtk-xenial
  sudo add-apt-repository ppa:savoury1/qt-xenial
  sudo add-apt-repository ppa:savoury1/kde-xenial

NOTE FOR ALL: After adding all required PPAs (see above) do these steps:

  sudo apt-get update
  sudo apt-get upgrade && sudo apt-get dist-upgrade
