Unable to locate package libcfitsio3

Question

I am trying to install the presto pulsar software.

I am at the first step in which I have to install some packages. I am entering the following command:

"sudo apt-get install git libfftw3-bin libfftw3-dbg libfftw3-dev libfftw3-doc libfftw3-double3 libfftw3-long3 libfftw3-quad3 libfftw3-single3 pgplot5 csh automake gfortran libglib2.0-dev libccfits-dev libcfitsio3 libcfitsio3-dev"

I have tried navigating over to the ubuntu website to search for libscfitsio and I found some libscfitsio packages on the ubuntu website but I don't understand how to install them through the bash shell. This an image of the errors that I have received:

enter image description here

Unable to locate package libcfitsio3

Package libcfitsio3-dev has no installation candidate

I have tried entering all the variations of libcfitsio into the bash shell. I always get the error "Unable to locate package libcfitsio." What I don't understand is if I went on the ubuntu website and I searched for libcfitsio and I got some results on the ubuntu website, why is the shell unable to locate anything?

Answer 1

The problem was that there's no package in the name libcfitsio3 in the ubuntu repository. See my results with ubuntu command apt search down below. In fact there's couple of packages related to libcfitsio and it shows there's updated version libcfitsio7`. You can install any of those according to your requirement.

PS: You don't have to search all those sites for package availabily. apt search <name> lists all your required packages from the main repository. Just make sure you run apt update to update to fetch latest from the remote repositories.

Answer 2

relevant package name is libcfitsio-dev, so use:

sudo apt-get install libcfitsio-dev

I used the above to install cfitsio via GitHub Actions with ubuntu-latest
