Hello,
sorry for the late response.
From the screenshot it is stuck at creating a storage file, depending on the disk IO speed it can take a while.
You can pass the --debug flag to the installation script to view the actual progress.
bash <(curl -sSL https://openpanel.org) --debug
Or you can set a smaller file for now and increase it later when needed. For example, to allocate only 50GB for docker, pass --docker-space=50 where 50 is the size in GB.
bash <(curl -sSL https://openpanel.org) --docker-space=50 --debug
Even with that if it is still going on, I will be more than happy to handle the installation process, simply reinstall the OS and send the ssh logins.
