Run the command apt-get update && apt-get upgrade -t Debian_10Check that icecast is not listed in the list of packages you are updating (yes, this does look strange - see Icecast Installation instructions for more here)
Run the command reboot now to reboot the VPS
This should take less than 5 minutes to come back up. If after this time, you cannot SSH into the VPS, login to the Linode web panel and confirm what the VPS is doing.
Once you have been able to SSH into the VPS - run the command systemctl status icecast2.service and confirm that the “Active” is “active (running)”
Go to the Icecast web interface and confirm that the page loads. (There should not be anything streaming to it, if there is - you did a bad and need to fix it now)
