Hi there. I hve been trying to isntall install gnuplot in this Ubuntu 14.04 laptop. I have successfully done it in other machines, including virtual but for some reason it does not work here.

For instance:

I do it again, the Ubuntu goes through all normal steps and as a result I still do not have the package. Why?

Gnuplot, Ubuntu 14.04 Trusty : The universe repository
http://packages.ubuntu.com/trusty/gnuplot

$ sudo apt-get update && sudo apt-get install gnuplot

And / or do a search : $ apt-cache search gnuplot

... If no package ``gnuplot´´ :
Please enable "universe" →
$ sudo apt-get install synaptic
→ → Open the Synaptic package manager >> Settings >> Repositories
... and tick universe, multiverse, restricted.

Install gnuplot-x11 with package manager.

Thanks for suggestions. Search command:

I don't uderstand the output. I've tried to install gnuplot-qt and gnuplot-nox with the same negative result. Will try other commands suggested. Thanks.

Well, I donm't think the install synaptic succeeded. All I got was a bunch of errors it seems. Also I want to stress I have installed gnuplot on other Ubuntu machines, including my virtual machine with no problem however now I don't have access to any of them temporarily and am working from my laptop.

Also I don't know how to get to Synaptic Package Manager however it may be a moot point now since I dom't think the synaptic is in my laptop.

Thanks for your help. - A.

Post #1 says : "Ubuntu 14.04".

But post #5 : "raring" → → That's the outdated Ubuntu 13.04 !

? What's the output from the command $ cat /etc/issue

Also : Please show your file /etc/apt/sources.list

knudfl hi. You are correct. It is Ubuntu 13.04. I was not aware of this. It is a confusing situation for me. I am bedridden now and another family member gave me this laptop and set up a remote desktop with an rack mount R5400 system. On that machine with a double boot the Ubuntu is definitely 14.04 but in the laptop it seems to be 13.04:

I actually tried to install gnuplot on both machines with the same result. And I know for a fact I have gnuplot in my rackmount because I used it so many times before. I also just found out I cannot install Java either with the same manifestations: Ubuntu goes through the motions, gives me all this copious output and after I try to use javac command it point me to the packages to install which I just installed.

I also ran an update command this morning and hoped that if there was an old version here it would be updated. Nothing like this happened however.

So, I don't know what to do and until I recovered and took possession of may rack mount I am handicapped. Thanks.

This is the file you are requesting. I understand it only partially. Could you comment? I can probably reinstall the Ubuntu 14.04. I do have a CD here.

Sorry I decided to remove the content of the quote because I don't think it is of interest to anybody anymore.

← #7 .

Ubuntu 13.04 was obviously moved to "old releases",
and you will have to replace the content of /etc/apt/sources.list with :

Thank you. It does not allow me to save he new content. I do have admin privileges on this laptop now but it does not ask me for my sudo credentail. I will try another approach now.

There is no way I can do anything about this file. Permission denied is the answer when I try to save your code in a separate text file and copy it to /etc/apt/sources.list. I will have to reinstall Ubuntu it seems. A.

← #10 .

HOWTO edit /etc/apt/sources.list :
$ sudo gedit /etc/apt/sources.list

Or replace 'gedit' with your preferred editor.

Amazingly, it worked. I don't understand now why it did not work for me in the first place. I opened it in gedit. Perhaps I forgot to use the sudo command. Now I will try to install gnuplot again. Thanks, - A.

Now I have a different problem:

It was able to locate it before.

← #13 .

The commands are :

$ sudo apt-get update
$ apt-cache search gnuplot
$ sudo apt-get install gnuplot

... Or you can use 'synaptic'.
* The `Refresh´ button will do the required 'apt-get update'.

Thank you very much for your help, however, the attempt resulted in failure and it is not your fault. I have two machines here: one is a laptop with Ubuntu 13.04 and the other is Dell rackmount R5400. So, another person set up a remote desktop for me from the laptop to the rackmount. I am temporary bedridden, this is why all this arrangement. So, in the rackmpount R5400 I have Ubuntui 14.04 and in the laptop this outdated Ubuntu 13.04. I know for a fact that I have gnuplot in the rackmount since I've used that package numerous times in the past.

Now, when I ran your three commands remotely they went through but most likely it did nothing to change the already installed software. Actually I have run all of them myself in the past two or three days. Every time I run a command I get a copious output which is hard for me to interprete. I am an application programmer and my mind is elsewhere.

So, my remote R5400 has the gnuplot and when I try to run a command: gnuplot file.gnu the system hangs up and I don't see the graphic. I began to suspect that for some weird reason the actual graphic is generated in my rackmount and I don't see it. I tried to send my wife there to describe what she saw but I could not figure out what it was. It is just a total mess.

So, I came up with an idea to copy all files I need to visualize into this laptop's directory, bypassing the remote desktop. However I cannot install gnuplot in the laptop. The system goes through the motions and comes up eventually with the same response: it offers me three packages for gnuplot to install as if I did not just install it the 15th time.

That's my story. I began this thread a few days ago and perhaps tomorrow I will get back my ability to walk again and the whole thing will become a moot point. Then I will go to my racmount and work.

I really appeciate your help. Some positive experience in analysing the system is what I am going to get out of it. Thanks, - A.
