I am trying to upgrade R 3.2.3-4 on Linux mint to at least version 3.4.4 (or any available there after).
Sadly, I'm struggling, and all Google efforts have failed.
I have repeated the same process several times using different locations, all have failed. My latest in /etc/apt/sources.list for R is:
deb https://www.stats.bris.ac.uk/R/ precise/
executing sudo apt-get update yields the error:
Err:13 https://www.stats.bris.ac.uk/R precise/ Packages
404 Not Found
A sudo-apt get install r-base
failed to update the current version.
I've tried several mirrored sites and they all return a 404.
Any ideas?
