Persistent "You do not seem to have the default distribution installed anymore."

[nodeselector]

After trying to install and switch to CentOS I found that the default Ubuntu 18.04 distro is being loaded:

root@MININT-GMBGKMA:/mnt/c/Users/jemartin# cat /etc/os-release
NAME="Ubuntu"
VERSION="18.04.1 LTS (Bionic Beaver)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 18.04.1 LTS"
VERSION_ID="18.04"
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
VERSION_CODENAME=bionic
UBUNTU_CODENAME=bionic
root@MININT-GMBGKMA:/mnt/c/Users/jemartin#

I checked switch.py to see what is being detected:

$ python switch.py
usage: ./switch.py image[:tag]

The following distributions are currently installed:

  - ubuntu:xenial*

You do not seem to have the default distribution installed anymore.
To reinstall it, run lxrun /uninstall and lxrun /install from the command prompt.

This persists after multiple attempts of lxrun uninstall/install.
