Install as AppImage
You can download the latest AppImage from the QOwnNotes releases page. It should be named like QOwnNotes-x86_64.AppImage on that page.
Tips
If you have jq installed, you can also download the latest AppImage directly:
# query the latest Linux release from the QOwnNotes API, parse the JSON for the URL and download it
curl -L https://api.qownnotes.org/latest_releases/linux | jq .url | xargs curl -Lo QOwnNotes-x86_64.AppImage
Then you can change the execute-permissions on the file:
chmod a+x QOwnNotes-*.AppImage
Tips
AppImages need libfuse2 to run! For example under Ubuntu you can install the library with sudo apt install libfuse2.
Afterward you should be able to execute the AppImage to run QOwnNotes.
Warning
If you want to use the automatic updater please make sure to put your AppImage in a place where your user account has write-access to, like somewhere in your home directory.
Tips
If you have troubles running the AppImage, because your glibc version is too old you can try the AppImage built on OBS, it should be built with glibc 2.16.
