Etcher error - writer process ended unexpectedly

I tried using etcher for the first time yesterday. I downloaded the default file “Linux x64” and installed. It is running in ubuntu 14.04. I had many problems including the error in topic…

I thought it might have to do with the USB flashdrive that I was using, so I went out and bought a new Transcend 8GB flash this morning. Still was getting the error message. So I tried installing the .deb version 1.4.4 from git – still get the same error message.

I’m tried several iso linux files – all verified. Currently trying to put xubuntu-18.04-desktop-amd64.iso onto my USB flashdrive.

Can you help?
