Cannot execute binary file apt-get

[kingrazor]

New to Debian. Just did a fresh install and am attempting to run apt-get. When I run without su, I get denied permission. When I run this command:

su brian apt-get update

brian is my username. I get prompted for my password, then get the following error message:

/usr/bin/apt-get: /usr/bin/apt-get: cannot execute binary file

Doing the same thing works in a mint install I have running. Any ideas?

1) Become Root by inputting

Code: Select all

su

It will ask for the password
2)Then issue the command

Code: Select all

apt update

This got me a bit farther but then I get this message:

"Updating from such a repository can't be done securely, and is therefore disabled by default." I get this message even if I use

Code: Select all

--allow-unauthenticated

What does your sources list say, and sources.list.d ?

[kingrazor]

Sources.list:

#

# deb cdrom:[Debian GNU/Linux 9.4.0 _Stretch_ - Official amd64 DVD Binary-1 20180310-11:21]/ stretch contrib main

deb cdrom:[Debian GNU/Linux 9.4.0 _Stretch_ - Official amd64 DVD Binary-1 20180310-11:21]/ stretch contrib main

sources.list.d folder is empty

at this point it might be a good idea to mosey over to wiki.debian.org and see what they have to say about a good sources.list for stable.
only 1 entry seems too little to me, but i might be wrong.
and you should probably comment out the CD.
did you install without an internet connection? that would require manual configuration later on.

[arochester]

Change your sources list to

Code: Select all

deb http://deb.debian.org/debian stretch main contrib non-free

deb http://deb.debian.org/debian stretch-updates main contrib non-free

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

Copy and paste if necessary.

Try updating again.

That worked. Not sure why they didn't just include those sources as part of the default install.

The installer disables them if it can't connect during the install.
