if I select the recovery option in grub menu it hangs included a photo of it
I tried to do a fresh install again and same result
what is going wrong here?
the computer got core duo 2 processor and runs 64 mint 19

I'm no expert at PC's but I think a core duo 2 is a bit old for modern OS's using 64 bit.

I dont think its that, I'm running Ubuntu 18.04 with a current 64 bit kernel on a Core Duo:

Model name: Intel(R) Core(TM)2 Duo CPU E8500 @ 3.16GHz
Linux dc7800 4.19.23-rt14 #1 SMP PREEMPT RT Mon Feb 25 07:27:55 PST 2019 x86_64 x86_64 x86_64 GNU/Linux

Maybe a un-noticed build error?

got it up and working on Debian 9 with RT kernel

P17i92
I purchased a disk as my internet connection is not that good out in the dessert in SE Idaho and is not reliable.
I will follow this thread be silent as I have lots to learn.

Thanks for the guide. I updated from an earlier build today. I installed to a new SSD so I can always fall back to the old one if needed.


Here is an alternative way to update grub. It's only a preference. The grub-customizer may be better for new linux users but if you are more comfortable modifying text files try this. (replace gvim with your editor of choice)

Search for the submenu name and the menuentry name for the newly built rt kernel. For example:
submenu name: Advanced options for Linux Mint 19.1 MATE
menuentry name: Linux Mint 19.1 MATE, with Linux 4.19.1-rt3

Now copy/paste and combine these together with the ">" character:

"Advanced options for Linux Mint 19.1 MATE>Linux Mint 19.1 MATE, with Linux 4.19.1-rt3"

Edit /etc/default/grub

Change the GRUB_DEFAULT=0 line. Add the combined submenu and menuentry string as:

GRUB_DEFAULT="Advanced options for Linux Mint 19.1 MATE>Linux Mint 19.1 MATE, with Linux 4.19.1-rt3"

Then reboot.

Hello,
Thanks for the instructions - I have followed carefully -but when i get to "dpkg-checkbuilddeps"
I get error message "dpkg-checkbuilddeps: error: Unmet build dependencies: rtai-modules-3.4-9-rtai-686-pae intltool" How do I add this dependency? I thought it was already there?

Any help appreciated ...

Many thanks,

Step 1: Fetch the updates available for your computer using apt-get update command:

sudo apt-get update

Step 2: You can then use apt-get upgrade command will upgrade the current packages

sudo apt-get upgrade

dist-upgrade is a safer option than upgrade.

sudo apt-get install intltool

Did you build and install the kernel as per JT instructions then reboot with the newer kernel ?

Hello,

Thanks for the above - I have done everything as follows ... but still have error:
adam3d@adam3d:~/emc$ dpkg-checkbuilddeps
dpkg-checkbuilddeps: error: Unmet build dependencies: rtai-modules-3.4-9-rtai-686-pae

Please advise ...

Many thanks!

Did you configure for uspace ?

what is u space? - I only followed the instructions ... if upsace was included in the instructions, then I would have configured uspace?
