Want to upload ubuntu14 image

If you are unable to upload/unpack the Ubuntu 14 QCow2 Image as a custom Linode distribution, you might want to try installing Ubuntu 14 using one of Canonical's ARM64 .tar.gz images:

• Ubuntu 14.04.5 LTS (Trusty Tahr)

Alternatively, instead of running your VM as a Linux distribution which reached End of Life (EOL) in 2019, you may have better success running a modern/supported distribution and executing Ubuntu 14 within a Docker Container:

• Image Layer Details - ubuntu:14.04 | Docker Hub

For more information about running Docker and managing Docker files on a Linode, be sure to review the following documentation:

• How to Install and Use Docker on Ubuntu and Debian | Linode Docs
• How to Use Docker Images, Containers, and Dockerfiles in Depth | Linode Docs

If I subscribe to your support can your staff do this for me?

I don't think it is going to happen.
