I'm basically following this tutorial https://galactictalk.org/d/20-setting-up-stellar-core-on-centos-7 but on ubuntu and my node is giving the following errors:

    tlnagy changed the title to Node hung up on downloading history buckets? .

    tlnagy This configuration file keeps changing rapidly. To get an up to date version I would always check out this one directly from git:

    https://github.com/stellar/stellar-core/blob/master/docs/stellar-core_example.cfg

    I think they changed the URL where they host the history try using this one instead:

    [HISTORY.stellar]
get="curl http://history.stellar.org/{0} -o {1}"

[HISTORY.backup]
get="curl http://backupstore.blob.core.windows.net/backupstore/{0} -o {1}"

      I added those lines instead of the previous ones and restarted the service, but I'm still having the same issue?

        tlnagy It looks like a different error. Try to dumping the database and clearing buckets, so you have a fresh start.

          Ok cool. Looks like we're making some progress. I ran rm -rf on the buckets folder and then used stellar-core --newdb to reinitialize the database. I'm still having some issues with the history:

          Hi, did you find the issue about the History Error? I've got the same message

          2 months later

          Anybody found the problem ? Same problem with me "error loading history state: rapidjson internal assertion failure: IsObject()"
