neblio-Qt Will Not Start Due to a Corrupt Blockchain
Occasionally if the computer neblio-Qt is running on unexpectedly crashes, or if the neblio-Qt process is forced to close, the blockchain database can become corrupt. This can cause a variety of errors that prevent neblio-Qt from restarting, for example:
The fix for this is simple, simply delete the blockchain and databases, and let neblio-Qt resync.
- Close neblio-qt
- Locate the data folder for your operating system (this may be a hidden folder):
Windows: %APPDATA%\neblio\ macOS: ~/Library/Application Support/neblio/ Linux or RPi: ~/.neblio/
- Copy the wallet.dat file from this folder to somewhere safe, such as your desktop.
- Delete everything in this folder EXCEPT wallet.dat, including the folders. The wallet.dat file contains your private keys, DO NOT DELETE IT.
- Restart neblio-Qt. The wallet will load your private keys from the wallet.dat file and begin downloading a new copy of the blockchain. Once the wallet is fully synced, you will see your NEBL in the wallet.
