I'm on ubuntu 14.4 and monero used to work, but now I'm getting the following error. I'm not sure how to fix this.

  • Check whether you don't already have a monerod running.

Make sure you don't have another monerod service running. I had to kill mine and start it again to get it to work.

  • ps -aux | grep monero
  • kill < id >

Get the id from ps and then kill it.
