Linux AppImage FAQ

Do I need root privileges to run the Dev Calls AppImage?

No. The AppImage runs entirely from your user account: download it, mark it executable and launch it. No package manager and no sudo required.

Which Linux distributions are supported?

Any modern x86_64 distribution with glibc 2.31 or newer, including Ubuntu 20.04+, Debian 11+, Fedora 36+, RHEL 9+, Arch Linux, openSUSE and Linux Mint.

The AppImage does not start — what should I check?

Make sure the file is executable (chmod +x) and that FUSE 2 is installed. On systems without FUSE you can run it with ./DevCalls-x86_64.AppImage --appimage-extract-and-run.

Should I choose the AppImage, the .deb or the .rpm?

Use the .deb on Debian and Ubuntu and the .rpm on Fedora and RHEL for system integration and updates. Pick the AppImage when you want a portable build with no installation.
