python-serial problem, updating Linuxcnc-dev to 2.8

Hello

I'm trying to update(Wheezy iso) linuxcnc-dev 2.7.15 to 2.8.

I get error:

Linuxcnc-dev: Depends: python-serial but it is not installable

I installed same setup while ago and had no issues.
Can i fix this?

Install python-serial, if so, then how?

I've found that you have to do two things to install software on Wheezy now that it is EOL, first is to change the apt source to point at the debian archives. (disabling all of the old debian repos). Then change the date on your computer to something before Wheezy expired. Then you should be able to run "sudo apt-get install python-serial". Once you've installed your software you can reset the date correct.

Hello

Thanks for answers.

I took a easy way and installed debian 9 iso.
it's still in maintenance and solved all my problems.

That is probably the better option if you don't need RTAI.

Hello

Do I have option to run 7i97 + 7i84 in realtime?

Pretty sure you must use a Preemt-RT kernel for Mesa's Ethernet boards. So for that an RTAI kernel is not an option. There is no good reason to even attempt to use Wheezy. Using Debian 9 or 10 are your best options.

PREEMPT_RT is mandatory for ANY Mesa ethernet board.
