sudo apt and so forth has confounded me.
 

O Wise Forum,

I'm fairly new to Debian, having jumped to it after Windows got boring and Mint was too straight forward and--frankly--not fast enough on my Frankenstein-rebuilt machine.

My question today is how to go about getting stuff downloaded. I want Midori and I want Flash Player for IceWeasel.

What I've done so far:

I've entered the following into the terminal:

$ su
#sudo apt-get update
Ign cdrom://[Debian GNU/Linux 8 _Jessie_ - Official Snapshot i386 LIVE/INSTALL Binary 20150425-15:14] jessie InRelease
Ign cdrom://[Debian GNU/Linux 8 _Jessie_ - Official Snapshot i386 LIVE/INSTALL Binary 20150425-15:14] jessie Release.gpg
Ign cdrom://[Debian GNU/Linux 8 _Jessie_ - Official Snapshot i386 LIVE/INSTALL Binary 20150425-15:14] jessie Release

Ign cdrom://[Debian GNU/Linux 8 _Jessie_ - Official Snapshot i386 LIVE/INSTALL Binary 20150425-15:14] jessie/main Translation-en

Reading package lists... Done

And then I'll go and try this:

# sudo apt-get install midori
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package midori

And a very similar thing happens when I tried to get my paws on Adobe Flash. I'm guessing my repositories are FUBAR'd somewhere along the line or something, but I'm not sure where to go from here. My extensive search of the interwebs has yielded only frustration and confusion. Help me, Obiwan Kenobie. I am only an egg.

Yours,
Derek

Don't know about apt but FYI as you have su'ed ( first line above ) you will be root so no real need to sudo as well, doesn't do any harm just unnecessary, also please use code tags see:

Try:Or any other string to find the actual package name. However "midori" should work, that would be the correct package name.

And since you're already root, you do not require sudo.

snap! ain't it odd when two people post the same thing at the same time!

It seems you don't have any "network mirrors" in your apt.list.
You could either reinstall and add them during install (can be easier in some ways) or check the Debian documentation and other help to add the relevant network repositories, which requires the internet but does make things easier.

Looks like you only have the installation ISO in your sources.list (along with the security line).

Post the content of /etc/apt/sources.list

It should look like this:
https://wiki.debian.org/SourcesList#...8_.22Jessie.22

Aside from this, you are in for a disappointment 'cos midori has been dropped from jessie (apparently it's a buggy pile of crap):
