I had this happen to me too.
In fact it happened first as I tried to install Mint 19.2, then I tried Lubuntu 19.04 and the same thing hppened.
And I can say I installed Mint 19.2 on a laptop first, with no problem.
I did search for a solution, and I did find one too:
On StackEchange
What you are saying about initird.img getting to big is exactly what happens. In my case it was the same as in the link, a 10 times as large file. Mine ended up at over 600 megabyte!
The instructions in the link are correct, but the commands needs to be applied to the image downloaded. Not in the locations shown in the thread, I tried that first, and that didn't work. But after trying it in the dir made in the process it worked!
So try:
Code:
find . -name *.ko -exec strip --strip-unneeded {} +
in the directory where you are making the RT kernel. The command is copy/paste from the thread, and should be applied exactly as this, with space before the + in the end.
I'm no Linux expert, so I can't say exactly at what stage of the process this should be done. I did it after first building the new kernel and trying to start it (and it failed). I had to boot in the non-RT version again to fix it.
So it if John Thornton (or someone with access to that site) could incorporate this in to those guides, with the correct details on when in the process to apply it, I think it might help others as well.
I also tried Wheezy, and that did work as expected. But seeing the interface compared to Mint made me go back to that HD and try some more.
I really do appreciate the opportunity to install LinuxCNC on a more modern and complete Linux version! The standard (Wheezy) version feels kind of..... simple, and also looks kind of old.
And now that we have a choice I'm happy! So thanks for the effort of making these guides. I would not be able to do this without them.
