Deja Dup Device Name Issue

  • 772

My Linux desktop is 4 years old. I originally named it "foo", but 2ish years ago renamed it "bar". I turned on backups for the first time today using Deja Dup, and it used the old computer/hostname from 4 years ago, "foo", as opposed to the current name "bar". I cannot figure out where the old hostname is coming from. I've verified the name is correct in the following locations:

  • /etc/hosts
  • /etc/hostname
  • hostname
  • hostnamectl
  • Settings > About > Device Name
  • python -c 'import socket; print socket.getfqdn()'
  • uname -n

I'm at a loss. I'm not sure where the old hostname would still be stored, and how Deja Dup is attempting to discern the computer name for the backup path. Any ideas?!

  1. I was having a similar problem with Deja Dup using my public IPv6 address. I solved it by changing /etc/hosts to this:

    127.0.0.1   localhost
127.0.1.1   computerName
::1         localhost ip6-localhost ip6-loopback

    The backups are now getting named properly to computerName and no longer changing.
