Linux Mint

PhotoQt for Linux Mint 19.1 can be easily installed by adding the following PPA to your system:

Open a terminal and type the following one line at a time:

sudo apt-add-repository ppa:lumas/photoqt
sudo apt update
sudo apt install photoqt

If you prefer to simply install PhotoQt from a deb file (i.e., without adding the PPA), you can do so here for a 32-Bit system and a 64-Bit system.
