View Full Version : [ubuntu] Re-installation problem

My 12.04 install has become slow and balky. I have downloaded the latest 12.04.2 ISO file to reinstall, but I can't get md5sum to check it. When I follow the instructions in "How to md5sum" I get nothing but error messages.
Can someone give me a (preferably graphical) method to verify the ISO file? I''m no good at typing long entries into the command line, so a click by click would be good. Thank you.

Hmm -- the only way I know how to check is through command line where you type:
md5sum <name of iso image>
If the iso image is so corrupted, possibly you'll get an error, however I've never exactly seen this.

I tried that, got the msg. no such file or directory. When I do whereis ubuntu-12.04.2-desktop-i386.iso, I just get the file name back.
When I downloaded, I saw no option to send the download to a folder or directory, it just went into downloads. If there is such an option which I missed, I'll remove that download and try again.
Thanks for your response.

Please post the exact command you tried.

May I suggest that you burn the ISO image to DVD/USB and run it. If it works, then it works! I have never checked the md5sum and I have tested many ISO images of the development release. I have had failures due to bugs in the Live session and in the Installer but never due to a bad download.
OH, by the way, when you ran that command to get the ms5sum of the ISO image were you in the Downloads directory? Did you cd Downloads?
Regards.

Morgaes; Sorry, don't have the keyboard characters handy to properly spell your name.
the command I used was ubuntu@ubuntu-desktop:~$ cd Downloads. also tried md5sum ubuntu-12.04.2-desktop:~$ cd Downloads.
I just stick with plain old Ubuntu, too many varieties of things are confusing to me, I'm easily confused anyway. Mostly I just use it and don't tinker with it unless necessary. I'm not really comfortable with using the command line.
grahammechanical;
cd downloads is on the end of both the commands listed above. Should I do cd downloads as a separate command before going to md5sum? In one of my previous installs, I had to make 3 CD's to get one that would work, I did md5sum on one which worked.
Thank you both

The command should be
md5sum ubuntu-12.04.2-desktop.iso or something like that.
If you stand in the download directory, write for example
md5sum ubuntu-12 and push the TAB key then the rest of the word appears automagically (provided you don't have files with a similar name in the directory).

Thanks, I like that automagic stuff, especially when it does what I want it to do. I'll give it a try a bit later.
I'll try the install when I get an up to date backup done, whether I get the file image verified or not.
