Difficulty installing Firedrake in Kubuntu

[AchillesMa]

I had downloaded firedrake in the same system about 2 years ago and everything was fine. Few days back I decided to update it and I got a bunch errors. Unable to resolve all the errors, I uninstalled and tried to install it again.

There I again got an error message at end regarding the libsupermesh package, as of now it seems I need Cmake 3.18 and higher, and I currently run Kubuntu 20.04 which is based on Cmake 3.16.3.

My question is since I do not want to mess with Cmake, is there any chance that there is an previous firedrake-install script needing 3.16 Cmake?

It's not the install script which uses CMake, it's various compiled dependencies that the install script installs. Using an old install script isn't going to wind back those dependencies. Simply installing a more recent CMake is the easiest way out of your current issue.

Thank you for your reply. I see, it makes more sense. I will try updating CMake

You may want to keep in mind that kitware offers an apt repository at https://apt.kitware.com/, I am quite sure that with that you would easily install a recent cmake version.

Thank you so much, that's quite helpful. Do I still need to uninstall the version installed with Kubuntu?

[francesco-ballarin]

No. If everything works correctly, you should be asked to upgrade your existing version 3.16.3 to the one currently available in the kitware repo.

Thank you again. I will try this.
