# Bitcoin Core Re-install- Don't want to Overwrite Chain Previously Downloaded

(Asked by: username_0 on 2020-07-23)

I have a full Bitcoin chain that I downloaded using Bitcoin Core (v.0.18.0.0, from Ubuntu's launchpad [bitcoin ppa](https://launchpad.net/%7Ebitcoin)). I've moved to another machine and installed the Snap linked from [BitcoinCore.Org](https://bitcoincore.org/en/download/), pointing it at my `.bitcoin` directory. When I run it, I get the following message. Before I hit "OK", I want to make sure I'm not going to nuke my already downloaded chain. Can anyone confirm?

Is there any chance running that Snap might cause any issues with my wallet and already downloaded blockchain?

The Snap (v.0.20.0) is having various issues, some of which are mentioned [here](https://github.com/bitcoin-core/packaging/issues/48). As mentioned above, the Ubuntu PPA is saying that it shouldn't be used. There is apparently a second PPA that is [at least semi-official](https://github.com/bitcoin-core/packaging/issues/36). That works and doesn't overwrite my chain.
