A script to automate installing and updating Anytype via AppImage based on the same script for Joplin: https://github.com/laurent22/joplin/blob/dev/Joplin_install_and_update.sh
This will handle the --no-sandbox issue that modern (as of this writing) Ubuntu based distros face with AppImage releases. For example, this sets up the KDE/plasma launcher and icon correctly, just like the Joplin one does.
You can do the modern thing of download and run a script blind from the internet like so:
wget -O - https://raw.githubusercontent.com/draggor/anytype-install-and-update/main/Anytype_install_and_update.sh | bash
Seriously though, give it a read!
By default it will install the AppImage to $HOME/.anytype/.
