Hello everyone, I'm trying to upgrade R from 3.6.3 to 4.0.0 using the linux
terminal commands (sudo apt upgrade r-base r-base-dev) but I get a message
that says 3.6.3 is still the latest version. Please see the output below.
How could I fix this?

Thanks much for your help!

Carlos

Did you update your software sources (/etc/apt/sources.list or entry in /etc/apt/sources.list.d)?
