I have installed Ubuntu 14.04.1. I tried installing Gnupolot, gfortran using sudo ap get install, but the terminal shows 'unable to locate package gnuplot-x11' and 'The following package cannot be authenticated'.

For gnuplot
, do you have universe
repository enabled? Should be there:
[romano:~] % apt-cache policy gnuplot-x11
gnuplot-x11:
Installed: 4.6.4-2
Candidate: 4.6.4-2
Version table:
*** 4.6.4-2 0
500 http://archive.ubuntu.com/ubuntu/ trusty/universe amd64 Packages
100 /var/lib/dpkg/status
gfortran
, instead, is in main
; should be installed without any problem:
[romano:~] % apt-cache policy gfortran
gfortran:
Installed: (none)
Candidate: 4:4.8.2-1ubuntu6
Version table:
4:4.8.2-1ubuntu6 0
500 http://archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages
...so please edit your question to report the exact errors you have.
