[BUG] Key-Error - Chia wallet not loading (latest checkout)

After checking out the newest commit, I’m unable to start the wallet:

Just a quick follow-up:

I have now deleted

(location: ~/.chia/mainnet/wallet/db/)

• blockchain_wallet_v1_mainnet_“somenumber”.sqlite and (location: ~/.chia/mainnet/db/)
• blockchain_v1_mainnet.sqlite

I have then closed and restarted chia. Unfortunately, with the deletion of the blockchain-db, you’ll have to resync.

I ran out of space yesterday and wallet keeps throwing the same error ever since.

Would it be possible to delete only the db of the wallet so I wouldn’t have to re-sync for another 3 days? Or the db and wallet db are bound together?

Yes, you can!

Here’s what I did it in Linux:

• cd ~/.chia/
• cp -r mainnet mainnet.old
• rm -r mainnet/wallet
• Run the Chia GUI
• Insert the seed to my private key

The whole blockchain will be there and you’ll be farming straight away

In case you have any height farmed, you’ll have to manually edit the sqlite file to insert the data that was previously there since the Chia GUI won’t re-scan the blockchain to figure out if you ever won anything in your wallet.

It shouldn’t be hard to use some program like sqlitebrowser and manually restore the data related to the coins that you earned but it’s just cosmetic.

Edit: After a few hours the chia client realized that I had a balance and updated to the right values without me having to do anything.
