My Ubuntu version is 18.04. The error is as follows which only appears in the middle of uploading backup files:

Giving up after 5 attempts. Error: gdata-service-error-quark: Authentication required: {
 "error": {
  "errors": [
    "domain": "global",
    "reason": "authError",
    "message": "Invalid Credentials",
    "locationType": "header",
    "location": "Authorization"
  "code": 401,
  "message": "Invalid Credentials"

I found the this same question 18.10 Deja Dup Backup error but there is no answer. Also can't find any solution elsewhere.

Another question is that if there is another way to backup Ubuntu with Google drive, without using Deja Dup?

  • No, it does not mention the problem.
