I have installed Haskell Platform in Ubuntu 14.04 using
sudo apt-get install haskell-platform
following the instructions from the official website.
The version of GHC installed as a result is 7.6.3.
I would like to update my version of GHC to a higher version. However, if I do something like
sudo apt-get install --only-upgrade ghc
based on this, I get
ghc is already the newest version.
I suppose separately downloading ghc and installing again can cause problems with other packages installed by Haskell Platform?
How can I correctly upgrade GHC?
Thank you.
The only way you can get the latest version is to install the Generic Linux version following the directions found here.
0) Always remember to safeguard your system against unintended consequences with a good backup strategy.
1) Download the installation tarball from the page shown below:
that matches the architecture of your installation and verify the hash matches with the command sha256sum filename where filename is the name of the file you downloaded.
2) Extract the content of the archive and note where you are extracting to.
3) change to the directory you extracted to in the step above and run the installation script with sudo ./install-haskell-platform.sh
Note: There are further details on the installation page for those of you running Ubuntu 16.10 or higher.
