Trouble installing on Pi: unmet dependencies

question
package

#1

Hi, I am having trouble installing Julia on my Raspberry Pi 2 Model B. I get the following error message:

$ sudo apt install julia
Reading package lists… Done
Building dependency tree
Reading state information… Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
julia : Depends: libamd2.3.1 but it is not installable
Depends: libcamd2.3.1 but it is not installable
Depends: libcholmod2.1.2 but it is not installable
Depends: libcolamd2.8.0 but it is not installable
Depends: libspqr1.3.1 but it is not installable
Depends: libumfpack5.6.2 but it is not installable
Depends: libopenspecfun0 but it is not installable
E: Unable to correct problems, you have held broken packages.

I am running Raspbian stretch:

cat /etc/apt/sources.list deb http://mirrordirector.raspbian.org/raspbian/ stretch main contrib non-free rpi cat /etc/issue
Raspbian GNU/Linux 9 \n \l

Any help would be appreciated.
