The process of packaging the software in AppImage is a storage file provide by the developer.
This file is a compressed image with all the dependencies and libraries needed to run the desired software. The AppImage doesn’t really install the software just execute it without no extraction and no installation.
The most common features:
- Can run on various different Linux distributions;
- No need of installing and compiling software;
- No need of root permission and the system files are not touched;
- Can be run anywhere including live disks;
- Applications are in read only mode;
- Software are removed just by just deleting the AppImage file;
- Applications packaged in AppImage are not sandboxed by default.
I tested the Krita Next with this tool.
The appimage file of Krita Next can be found here.
About the Krita Next this is a daily builds that contain new features, but could be unstable.
After I download the file I change it to executable with:
[mythcat@desk Downloads]$ chmod +x krita-4.2.0-pre-alpha-95773b5-x86_64.appimage [mythcat@desk Downloads]$ ./krita-4.2.0-pre-alpha-95773b5-x86_64.appimage
