Document how to synchronize with the network quickly via out-of-band catch-up on Ubuntu nodes.
We already have similar documentation for macOS and Windows.
The process is a bit more involved on Ubuntu (than on macOS and Windows) due to the sandboxing, so you cannot just put the file anywhere you want.
We already have documentation for how to add baker credentials to an Ubuntu node, which faces the sandboxing issues, so read that guide for inspiration.
