Yeah, all of those with complicated setups on a RPi were most often new to Linux, new to Docker, and also new to Syncthing – a relatively steep learning curve tackling all three simultaneously.
Some tips for your wallabag:
- Skip Docker – at least at the beginning – and go bare-metal for a much simpler setup.
- Install Raspberry Pi OS Lite – if you don’t absolutely require a desktop environment, the range of RPi models that can be successfully paired with Syncthing is a lot better.
- Install the stock Syncthing package from the Raspberry Pi OS repo, or the latest release from Syncthing’s official APT repo https://apt.syncthing.net/.
- For external storage, avoid formatting volumes as NTFS unless there’s a very good reason to. Use ext4 or exFAT with most RPi models, but if it’s a more powerful model such as RPi 4 or 5 and you’re syncing a lot of small files and/or would like additional data integrity features, consider using btrfs.
