I read at
https://itsfoss.com/ that Linux Mint 19 has been released today & having already used the beta live disc to test it out I was keen to upgrade from 18.3. It states that upgrade is possible from within the update manager under "Edit" however I have refreshed my update manager expecting to see the "Upgrade to Mint 19" under the Edit tab but there's nothing there.
Is it being pushed out slowly or should I be able to get it now.
I also wonder is there a command line way to force it.
Thanks
