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

Bitcoin Asked by Diagon on December 10, 2021

I have a full Bitcoin chain that I downloaded using Bitcoin Core (v., from Ubuntu’s launchpad bitcoin ppa). I’ve moved to another machine and installed the Snap linked from BitcoinCore.Org, 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?

As this is the first time the program is launched, … Bitcoin Core will download and store a copy of the Bitcoin block chain…. The wallet will also be stored in this directory.

[ ] use the default data directory
[x] use a custom data directory

When you click OK, Bitcoin Core will begin to download and process the full Bitcoin block chain (320GB) ….

[ ] Discard blocks after verification, except most recent 2 GB (prune)

Also, it’s been a while since I looked, but the Ubuntu PPA stable channel is now saying:

NOT MAINTAINED. The OS-library linking packages here had a series of issues.

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

One Answer

The Snap (v.0.20.0) is having various issues, some of which are mentioned here. 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. That works and doesn't overwrite my chain.
