SOLVED Unable to Update or Go to Software Sources

[fat_beard]

First off I am 2 days in LMDE 4, been using LM 19 since last January. Please be gentle with me.

I was almost done setting up everything I needed for software wise....I was trying to get WINE and LUTRIS but to no avail, I either couldn't follow the instructions or something else was going on.

So now I cannot check for updates or even open Software Sources.

When I try to open Software Sources via through Updates at the top left of Edit in Software Manager, it'll ask me for my password, enter it in, then nothing. Same when I go to Software Sources, password, enter, nothing.

How ever in Software Manager, when I select to refresh..I get an error occurred; (see photo)

I did try searching with the site:forums.linuxmint.com and I got a lot of info, how ever mainly for regular LM non DE. So I think I made matters worse;

I didn't have time to make a snapshot right away, was still setting everything up.

I am using LMDE 4, 64-bit:
CPU: 6-Core AMD FX-6350 (-MCP-) speed/min/max: 1720/1400/3900 MHz
Kernel: 4.19.0-13-amd64 x86_64 Up: 20m Mem: 1764.8/16000.6 MiB (11.0%)
Storage: 1.20 TiB (1.7% used) Procs: 206 Shell: bash 5.0.3 inxi: 3.0.32

Sorry if I didn't add anything or made a lot of jibbirish, it's 3:30 a.m.

Thank you for your time; ALL OF YOU, seriously!!!!

Open a terminal
sudo thunar >>> password
then go to etc/apt/sources.d and post

I feel dumb right now....I tried as you stated but I got this.

LMDE (and Mint) will use by default nemo as a file manager.

But go to a Terminal and enter:-
cat /etc/apt/sources.list.d/official-package-repositories.list
Paste the output in your reply.

Expect to see something like:-

Code: Select all

deb http://mirror6.layerjet.com/linuxmint/packages debbie main upstream import backport 

deb https://deb.debian.org/debian/ buster main contrib non-free
deb https://deb.debian.org/debian/ buster-updates main contrib non-free
deb http://security.debian.org/ buster/updates main contrib non-free

deb https://deb.debian.org/debian/ buster-backports main contrib non-free
