How do I import snapshots running a full node from Ubuntu 16?

Question

I have followed these instructions to start running the tezos mainnet (up to "git checkout mainnet".

Then I have gone ahead and downloaded the full node via this git repo: https://github.com/Phlogi/tezos-snapshots

What are the next steps to restore/import the node from the snapshot? Thanks in advance!

You simply need to run ./tezos-node snapshot import FILE.full (you may need to specify your --data-dir path/to/dir if not using the default one).

For more details, the snapshot documentation can be found here: http://tezos.gitlab.io/user/snapshots.html.

Also the link you gave me on the tezos gitlab website is now downloading the dune protocol I think, the folder has dune workspace and dune text file in it....

Finally got it! you have to change the file name, tezos-node folder has to be set up and you have to unpack the zipped node, and you have to do it with unxz command... I will write in depth instructions later

"dune" is the build system used in Tezos (see github.com/ocaml/dune). It is not related to anything else. The node handles only uncompressed snapshots. Thus, depending on the format of the snapshot you have downloaded, you may need to do other manipulations. The next update of snapshots will give a better error when providing incompatible files :)
