Hi all, I have a brand new desktop pc without any OS and I wish to install Ubuntu.
But, as all nice things in life, I need to have some adventure before enjoying.
So, I used a Live CD I found in a Ubuntu guide (probably an old version of Ubuntu, not quite sure which) and I got the screen asking:
Start or install Ubuntu (which I selected)
but then I got the error message that I have pasted on the title:
/bin/sh: can’t access tty: job control turned off

any help??

cheers,
vasilis

The first thing you should do is to rule out a corrupted live CD.
You should run the check CD for defects option from the live CD.
See this: https://help.ubuntu.com/community/In...IntegrityCheck
This will take a minute or 2 to run. If it reports no errors the CD is good.
If it reports errors, then check the md5sums of the Ubuntu iso image that you downloaded: https://help.ubuntu.com/community/HowToMD5SUM
If the md5sum of the downloaded iso image is good, then burn a new CD at the slowest possible speed to avoid errors. If the md5sum of the downloaded iso is bad, then you will need to download a new iso image, preferably from a different mirror.

IF the CD integrity check passes and you still can not install Ubuntu, then write back, because you must have another problem.
Here is a great site for getting started with Ubuntu that is kept up to date: http://psychocats.net/ubuntu/

And welcome to the LQ forums!

If you come across a similar problem, it is better to use the latest stable release of Linux, as the older ones are probably not able to cope with new architecture of PCs.
