    Running dash-qt from terminal on Ubuntu 18.04. Wallet GUI appears for a few seconds then closes. Error reads:

    dash-qt: evo/evodb.cpp:33: bool CEvoDB::VerifyBestBlock(const uint256&): Assertion `hashBestBlock == hashBlockIndex' failed.
    Aborted (core dumped)

    Thoughts?

    Which version are you running of Dash ? Make sure you are running latest version 0.14.0.2

    If you still have problems with latest version, then first check your debug.log (it may mention you need a -reindex)

    Options available :

    Option 1 : Try a -reindex to see if that gets your wallet started

    Option 2 : Make a backup of the evodb folder --> rename that backup to nonevodb --> remove the orginal evodb folder --> start wallet with -reindex
    * if that works and your wallet starts normally, you can then delete your nonevodb backup folder

    Option 3 : Delete your blockchain and sync from scratch (you can download a bootstrap here : https://github.com/UdjinM6/dash-bootstrap)
    * when bootstrap is finished it will rename itself to "bootstrap.dat.old" and you can then delete it

    The whole blockchain downloaded recently, before this problem started. Now the error happens before download begins.

    Maybe you got a bad block somewhere, it can happen, have you tried reindexing the wallet?


    What OS are you running Dashcore wallet with, and are you running an MN?
