Running Software Downloaded From Internet

Was running Windows 8.1 Pro till it got sick and died. I managed to install Ubuntu 14.04 on my sick computer over Windows wiping it out.

I first installed Linux Mint and downloaded Ubuntu. Somehow I was able to verify checksums or MD5Sums. I think my age is catching up with me and my mind doesn't work like it used to.

How do I find the MD5sum of a downloaded iso file. I've downloaded debian-7.8.0-amd64-DVD-1-3.iso's and both update DVD's as well. I've located the MD5Sum files on the Mirror. Now, how do I compare those numbers/letters with the iso's I've downloaded.

I know I need to run a program to compute the MD5 but can't find it in the menu. I see I need to read man pages and info pages, but can't find them either.

A brain is a terrible thing to waste, but mine needs help.

Thanks,
Stephen

I have downloaded an attachment from a website and an icon has now appeared on the bottom panel of my debian distro with gnome shell (classic).
This icon will not go away even with reboot.
If I right-click on the icon it offers me 'launch' and 'properties' option. But there is no 'delete' option.

If I click on the icon it will take me back to the same website and open the attachment again.
Now it's forever on the bottom panel of my desktop.
Clearly this is a bug.
Can someone please advise how I can get rid of this? Thank you in advance.

I have downloaded the JMRI/Decoder Pro package. When I go to open Decoder Pro I get the screen which asks, Run in Terminal, Display, ,?, and Run. If I select Run I get no response, If I select Run in Terminal The Terminal screen flashes for only a second and dissapears.

I have not been able to get an Icon to launch the program from my desktop.

I am usung Linux Mint 16 (Petra)3.11.0-12 generic (MATE) 1.6.1

JMRI is the standard download for Linux from Source . org.

I am new to both Linux (3 yrs) JMRI had worked with it some in Windows, Totally new in Linux.

I don't know what else to include, I'll be happy to answer questions.

Brand-spankin' new newbie here, and I can't figure out how to open my files I've downloaded. I've downloaded some .exe's, but can't figure out how to open them, and haven't found anyplace via Google that can help with this fundamental problem. I know this is obviously a simple issue, but I can't figure it out and am very frustrated!!! I totally appreciate any constructive feedback, thanks much. Steve

Hi everyone!

Having read about the latest LibreOffice version, I felt tempted to try it out. I uninstalled the default version on my Ubuntu machine and downloaded the .deb from the LibreOffice site and installed it. The new office has since worked without any trouble.

A few days later I decided to dump Unity and go back to Gnome. So I installed Ubuntu-Gnome-Desktop.

It was then that I noticed two versions of LibreOffice on the application dash (I think, because there are two sets of icons for each office application- see the attached screenshot).

Did Gnome install its own version of LibreOffice with it? Does it really have one? I don't know.

Whichever icon I use to launch the app, the office however always brings up the latest version. So, there's no problem in terms of application errors. As I thought there's no need to have an extra version of an app and eat up my space, I tried to uninstall through Aptitude, but it doesn't 'remove' LibreOffice.

Any advice, please! Thanks in advance.

I have downloaded Mageia 4 and it says that after downloading I should verify the signatures. I burned the ISO to a DVD and explored that but no luck. Please could someone tell me how I verify a signature. This must be basic stuff but it stumped me.

I have downloaded ubuntu.
I wish to uses open office.
I was told to remove a symlink.
Where do I Start.
The instructions from wikihow is suitably vague for a beginner!

Greetings,
I have three questions about free software for the disabled and blind user.

1) Which operating system distribution of free, open-source software is good for the disabled and blind user?

2) What about a desktop environment and window manager that is good for the disabled and blind user?

3) What about application selection for the disabled and blind user?

Thank you

Hello,

I downloaded source code for Sage math application and compiled (make command) it on a test Centos 6.4. Did some testing and all. Can I move the directory to another machine with the same Centos version?
