For those prefer installing apps via apt method, the digital painting software Krita 4.4.2 now is available to install via another well trusted PPA for Ubuntu 20.04, Ubuntu 20.10, Linux Mint 20.
Krita 4.4.2 was released a week ago as the latest version of the free open-source painting software, with new features: SVG mesh Gradients, mesh transform, new gradient fill layer type, new brushes, and improved HiDPI support.
While the official packages in Krita Lime PPA for some reason stuck at version 4.4.0, the Ubuntu Studio Backports PPA now maintains the latest packages for Ubuntu 20.04 and ubuntu 20.10.
As an official Ubuntu flavor for audio / video production, graphics desigin, photography, and desktop publishing, Ubuntu Studio also maintains the most recent packages of Audacity, Darktable, DigiKam, GIMP, OBS Studio, etc in the PPA.
