Tried every net solution for days to install linuxcnc

Solution Found! Even though my main internal hard drive was successfully installing debian12, debian13, linuxcnc/debian12, mint, etc. the reboot to the new OS would fail with “no boot device found” It turns out that booting to a root starting point is much more difficult for a HD than going through the whole installation processes. The disk past the first BIOS test but failed the “short test” I got another HDD that did pass the shot test in the BIOS system check. Debian13 now boots with all green “OK” from a check list that runs at boot up (and shut down) all the way to it’s login then desktop.

Thanks Rodw, you pegged the problem from the beginning. I will get an internal SSD to replace my HDD as you suggested. I learned…

“typical HDD speeds ranging from 30-150 MB/s while SSDs can reach speeds between 500 MB/s and 3,500 MB/s or more “

The LinuxCNC was not pre-loaded, and the…

sudo apt update
and
sudo apt install linuxcnc-uspace linuxcnc-uspace-dev

Were not allowed in any of the 4 terminal options under system tools. The sudo command fails because when it asked for my password, it would not accept any input. The cursor did not move and no “******” to hide input were created.

[sudo] password for “username”:

The return or response after typing in the correct password anyway was…

“username” is not in the sudoers file,

Anybody know why this is happening?

The LinuxCNC was not pre-loaded, with Debian 13/ trixie new install.

Solution found! This worked for me...

“When you installed Debian, did you set a root password? If so, sudo might not be installed. If it’s a fresh install and you’re not too sure of what you’re doing, I’d do a clean install but this time supplying no root password when asked. It’ll ask for a sudo username and password and disable root login. “

Great you are under way! We don't usually add a root user and use sudo to access anything as root
To install software with apt, you would log in as root and skip typing sudo.
Point 10 of my document outlines how to add your user to the sudoers group

Thanks again for your help Rodw, It is nice to know that there are people like you that know this stuff and can answer the difficult questions.
