How do I install rtlinux in Ubuntu? If I get it to install will it make software work abnormally?
From : https://wiki.ubuntu.com/RealTime , [...]The -preempt and -rt kernels are no longer being developed due to lack of support[...]
I've come across some posts on Ubuntu forums (dated 2008), that mentioned the packages for a rtlinux were on the repos however i have looked them for you and they are no longer available. Seems like the last version that had them on the repos was 10.04.
For installation on 10.04:
On Synaptic search for "rt Linux" then pick the following package
It will install the following packages:
Then just restart, on GRUB pick kernel 2.6.31-10-rt and you're done.
