Troubleshooting Ubuntu Pro

Frequently Reported Issues

1. Invalid Token error when running command: sudo pro attach $(vmware-rpctool "info-get guestinfo.ut.vss.ubuntu_pro.token")

Solution:

Ensure the virtual machine is running on any of the clusters listed above.

vss-cli compute vm get {vm_id-or-name} domain

output:

MOREF : domain-c5877 NAME : FD3

 

Run the following command through the vss-cli to attach Ubuntu Pro to your virtual machine

vss-cli --wait compute vm set {vm_id-or-name} ubuntu-pro attach

output:

id : B399A status : SUBMITTED task_id : 29870123-XXXX-4a03-894a-f350481XXXXX message : Request has been accepted for processing ⏳ Waiting for request B399A to complete... 🎉 Request B399A completed successfully: warnings : Ubuntu Pro settings have been re-applied. errors :

 

Once you receive the confirmation that the Ubuntu Pro token is set up, proceed with updating packages on the desired virtual machine using the following commands:

sudo apt install ubuntu-advantage-pro ubuntu-advantage-tools sudo pro attach $(vmware-rpctool "info-get guestinfo.ut.vss.ubuntu_pro.token")

2. Error: Failed to attach machine. See https://ubuntu.com/pro/dashboard" 

Solution:
Ensure you can connect to the contract url: https://vss-ubuntu-pro.eis.utoronto.ca

Try the following command:

curl https://vss-ubuntu-pro.eis.utoronto.ca

output:

404 page not found

 

If your output is different, this means that you have a firewall or proxy configuration that is not allowing you to connect to our Ubuntu Pro instance. Feel free to contact us to troubleshoot further this issue.
