Receiving errors when install software

[RobGoss]

Hello everyone, I've been playing around with Debian 8 and have one issue, After installing it all seem to run ok but when I tried installing software I get this error message

 Please insert the disk labeled:
Debian GNU/Linux 8.8.0 _Jessie_ - Official amd64 DVD Binary-1 20170506-14:13
in drive /media/cdrom/

After doing some research I read that I have to remove the cdrom: from my source list, I am trying to do this using Gedit
I was able to remove the sections that needed to be removed but after that I cannot save the changes

This is my source list

# 

# deb cdrom:[Debian GNU/Linux 8.8.0 _Jessie_ - Official amd64 DVD Binary-1 20170506-14:13]/ jessie contrib main

deb cdrom:[Debian GNU/Linux 8.8.0 _Jessie_ - Official amd64 DVD Binary-1 20170506-14:13]/ jessie contrib main

deb http://ftp.us.debian.org/debian/ jessie main
deb-src http://ftp.us.debian.org/debian/ jessie main

deb http://security.debian.org/ jessie/updates main contrib
deb-src http://security.debian.org/ jessie/updates main contrib

# jessie-updates, previously known as 'volatile'
deb http://ftp.us.debian.org/debian/ jessie-updates main contrib
deb-src http://ftp.us.debian.org/debian/ jessie-updates main contrib

I understand I have to remove cdrom: from the first two listed but do I need to replace it with another resource list there. I cannot install any software when I try

Thanks so much

Did you elevate to root privileges? You need to do that to save your changes.

Coment out this line in your /etc/apt/source.list

deb cdrom:[Debian GNU/Linux 8.8.0 _Jessie_ - Official amd64 DVD Binary-1 20170506-14:13]/ jessie contrib main

So it looks like the first Via;

# deb cdrom:[Debian GNU/Linux 8.8.0 _Jessie_ - Official amd64 DVD Binary-1 20170506-14:13]/ jessie contrib main

Hello Dennis N, How would I do that? I tried the following, su -

1 Fallen, Yes I'm trying to make the changes but having trouble editing the source.list

What is your text editor?

[RobGoss]

What is your text editor?

I'm using gedit with Debian

Cool throw this in the terminal:

sudo -H gedit /etc/apt/sources.list

Now while your there you may as well add the non-free repo's as well.
Add these two lines.

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

###Also add the following line underneath the lines displayed above:###

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

Once configured, your re-configured source lines should look as follows:

# deb cdrom:[Debian GNU/Linux 8 _Jessie_...
# deb cdrom:[Debian GNU/Linux 8 _Jessie_...
deb http://security.debian.org/ jessie/updates main contrib non-free
deb-src http://security.debian.org/ jessie/updates main contrib non-free
deb http://http.us.debian.org/debian jessie main contrib non-free

Just mentioning that ...

sudo apt edit-sources

will probably work as well. This would open your sources.list giving a choice of editors but uses nano by default.

[Dennis N]

Yep. that ^ should work. I rarely run a GUI app like gedit as root. As an alternative, I would have suggested:

sudo nano /etc/apt/sources.list

when done, CTRL+O to save, CTRL+X to quit.
