Raspberry Pi not able to software install packages

[Rav-Singh]

Hello,

 

We have recently had some Raspberry Pi delivered and I have been given the task of getting them ready in order to show ICT teachers what they can do. Unfortunately I am not able to download anything at all, I thought I'd start by installing Chrome for Raspberry Pi by running the "sudo apt-get install chromium" command but it failed with the following error "unable to connect to mirrordirector.raspbian.org:http:". I have attached a picture of the error.

 

Please help

If you're doing this from within a school network did you set any of the proxies on the Pi? Else it wouldn't be able to connect through to the internet.

Are you behind a proxy? If so, you'll need something like 'export http_proxy="http://proxyname:port" and search this forum for apt.conf which will also want a proxy setting which I can't remember off the top of my head.

Hi Steve,

 

Many thanks for getting back to me. I have set the proxy using the GUI interface (startx command) and am able to use the internet. Im assuming this should also work using the command line interface? or are there additional setting for this?

 

Many Thanks

Hi Mats,

 

Where would i add 'export http_proxy="http://proxynameport" ? Is this the right command 'export http_proxy="http://eduproxy.bgfl.org80"? ('eduproxy.bgfl.org' being our proxy and '80' being the port) also can you point me in the right direction of the apt.conf forum as I cant find it.

 

Thanks

At the command line -

export http_proxy="http://eduproxy.bgfl.org/"

 

You don't need the port number if you're using port 80.

 

That gets wget working. To get apt-get using the proxy,

 

create /etc/apt/conf and add this line

Acquire::http::Proxy "http://eduproxy.bgfl.org";

 

This worked on an ubuntu 12.04 machine - I think the RaspPi is also debian based so you're in with a chance. Failing that, have you tried the pi forums?

I Have now been able to get to "/etc/apt/" by using the "cd /etc/apt" command however cant work out how to create "conf", sorry to be a pain!

 

Thanks

you need to :-

 

sudo nano /etc/apt/apt.conf

 

In there you have

Acquire::http::proxy "YOURPROXY/";

 

ctrl-x to escape then save

Hi Caffrey thank you for your reply, i have carried out the above but still had no joy, I think i may be doing something wrong. i have tried the commands as follows-

 

acquire::http:proxy "eduproxy.bgfl.org/";             no joy
acquire::http:proxy eduproxy.bgfl.org/;               no joy

Any ideas?

 

Thanks

Worked great for me to get apt working through a proxy for updates.

Capitals matter in Unix-like operating systems.

 

sudo nano /etc/apt/apt.conf < this starts the nano editor on file /etc/apt/apt.conf (some systems work with /etc/apt/conf)

 

Insert this line

Acquire::http::Proxy "http://eduproxy.bgfl.org:80";

 

Press ctrl x and save the file. Try

apt-get update 

again

Thanks Mats for your reply, I have entered the command and have managed to pull some files down but others have failed, is this normal? I have attached a picture please let me know what you think.

 

Many Thanks

So, a quick explanation of what happened. When you run "apt-get update" as user pi (your normal login user), apt-get can't write the files it needs to write because it's just a normal user.

 

When you run "sudo apt-get update", it runs the same program as the super-user aka root, who can write where it wants.

 

Normal stuff - use the pi user.

 

Admin stuff - sudo.

 

When you type "sudo bash", it runs bash - the command line interpreter - as the super user, with its almighty powers.

 

HTH,
