Thanks.
You suggestions worked. Managed to upgrade from debian 9 to buster10 on my laptop.

Followed the steps without errors on a Thinkpad T400. When booting I’m getting a black screen that flashes every 2 secs and the cursor is somewhat visible but can’t be moved.
Recovery mode Debian 8/3.16 kernel works.
Is there a way to go back to Stretch?
Thank you.

Perhaps you’re using a proprietary Nvidia driver and it isn’t being upgraded properly? I’m worried that will happen to me, and taking precautions in advance.

Switchable Intel GMA 4500MHD and ATI Mobility Radeon HD 3470 video cards. Flashing blackscreen with both. IIRC the default video driver was installed in Stretch.

When I type in the command:
sed -i ‘s/stretch/buster/g’ /etc/apt/sources.list
I get response:
sed: couldn’t open temporary file /etc/apt/sedxSgci2: Permission denied
I think this is because a noexec flag was placed on it. Do you know any way to bypass this?

Run the command as root ( # ) user. First change to root:
$ su
and then execute the command:
# sed -i ‘s/stretch/buster/g’ /etc/apt/sources.list

It’s asking for a password. What do I do?
