I have upgraded two of my computers without problem. It is the the initial install that has problems.
I run a simple screen with fvwm on, x11 and use terms and emacs with no widgets etci cannot see how to install this. I know it can be done because of the upgraded machines…
Al I get is a screen with coloured strips and sometimes a console window. How do igetig to start my usual interface?
Are you booting by default into a terminal and wish to boot into your desktop environment?
In the installer, you can select it to boot into a tty interfece manualy but it is by default going to drop you into a window manager.
if you are in a terminal, you can type: StartX to start your x server which will drop you into a graphical environment if it is installed andd you do not encounter errors.
Follow this guide to change wether you boot into a terminal or desktop environment by default: https://www.cyberciti.biz/faq/switch-boot-target-to-text-gui-in-systemd-linux/
