This is extremely sad. I use Syncthing a lot to sync documents between my phone an my computer.
The main benefit over client/server-based solutions are that it always works.
No network connection? No problem, the files are all stored locally.
I broke my home server again? No problem, the devices can talk directly to each other.
The error message is very detailed and there is nothing to add to it.
If you want to install an application/CLI tool, use
pipx
or your system package manager. If you want to install a library, use a virtual environment (e.g. by usingpython -m venv
) or your system package manager.
