App: Linux: Snapshot in wrong directory after download

[diegorodriguezv]

Actual behavior:

After using the sync with snapshot feature and downloading the snapshot file the synchronization starts at 0%.

Expected behavior:

The synchronization should start at 95+%

How to reproduce it (as minimally and precisely as possible):

1. Delete the contents of ~/.defi/enhancedcs/ (or otherwise corrupt the database somehow)
2. Start the app
3. Use snaphot sync
4. Wait for file download and extraction
5. Synchronization will start back at 0%

What are your environment parameters?

• DeFi Wallet Version: 2.3.5
• Operating System (OS): Ubuntu 19.10
  – Current free storage capacity: 200GB

Anything else we need to know?

The problem seems to be that:

1. The snapshot file is downloaded to ~/snapshot (instead of ~/.defi/snapshot)
2. The contents are extracted to ~ instead of ~/.defi

Update. If I simply extract the snapshot to ~/.defi and open the app it will start synchronizing at 98.2%.

Hi @diegorodriguezv , in v2.3.5, after snapshot has been successfully extracted in-app, the app should prompt you with the option to delete.

What's your current directory file route for snapshot?

[angelocastiglione]

Yes, the snapshot will download at main directory "/home/......./snapshot" instead "/home/........./.defi/snapshot"

And the content are are extracted to "/home/......./" instead of "/home/......./.defi"

I didn't delete the snapshot file. Clicked "restart app" and it started back at 0%.
The snapshot is correctly downloaded at ~/snapshot. I verified and the contents are ok.

Yes, the snapshot will download at main directory "/home/......./snapshot" instead "/home/........./.defi/snapshot"
And the content are are extracted to "/home/......./" instead of "/home/......./.defi"

That's where I think the problem lies. I could see that there were 3 new folders at ~:

• enchancedcs
• chainstate
• blocks

But the app was not using them and started back at 0%. I quit the App and manually extracted the snapshot file to ~/.defi and it overwrote those 3 folders. After starting the App again it started at 98%.

Guys i found it, you just have to open the CLI, and manually add nodes for the blockchain to sync to them
just run these commands:

addnode 45.157.177.82:8555 add
addnode 24.134.79.25:8555 add
addnode 77.56.65.5:855 add
addnode 85.214.55.116:855 add

do not worry about the answer "null", if you type them twice it should answer "node already added"

then type getconnectioncount to see to how many nodes you are connected

here is a list of some public nodes you can connect to

@yungmann Wrong issue. :)

For Linux users who are facing this issue, kindly refer to @diegorodriguezv 's comment. Here's how to manually replace the contents from the downloaded Snapshot.

– After Snapshot is applied > click RESTART APP.
– If after restarting app, and it synchronisation starts again at 0%, proceed with the following:

1. Ensure app is not running
2. Go to your Defi folder [/Users/<username>/Library/Application Support/Defi], inside you'll see the following folders:
   enchancedcs
chainstate
blocks

1. Drag and replace the folders you downloaded from Snapshot and overwrite the 3 respective folders
2. Launch your app > Sync should start at 98%
