Kubuntu on VirtualBox: Can't install/update software

**Abu_Dayya** · May 2nd, 2011

I installed kubuntu 11.04 on an Windows7 PC inside a VirtualBox VM. I have setup the network connections proxy server (didn't accept hostnames btw, had to use the ip) and now i have connection to the internet, and to the UNIX servers that I manage. But I can't use kPackageKit or sudo apt-get update/upgrade/install/etc. Is there something I'm missing?

It appears to be something related to proxy. I added a proxy from System Settings -> Network Settings -> Proxy -> Manually specify proxy settings. It still doesn't work. And I can't also add my username and password in Network Settings -> Proxy. The radio button for adding username and password is grayed out. I can only choose "Prompt me".

I also tried adding the following entry in /etc/PackageKit/PackageKit.conf

Code:

ProxyHTTP=http://username:password@proxyip:port

I also did

Code:

echo http_proxy=http://username:password@proxyip:port >> $HOME/.bashrc
echo export http_proxy >> $HOME/.bashrc

Still can't install software. When hit 'check for new updates' in kpackagekit, it fails and throws an error about proxy authintication. I can still brows the internet through rekonq though.

One more thing, my password as an '@' char in it. could this be why its not working? I tried escaping it with '\' in both PackageKit.conf and .bashrc, and it still doesn't work. this is how it actually looks

Code:

echo http_proxy=http://yousef:passw\@rd@1.2.3.4:8080 >> $HOME/.bashrc
echo export http_proxy >> $HOME/.bashrc

Any help?

To configure a proxy for the packaging system, edit (or create) /etc/apt/apt.conf to add a proxy specification like this, and substitute appropriately:

Code:

Acquire::http::Proxy "http://[[user][:pass]@]host[:port]/";

Now apt-get, aptitude, synaptic, (and hopefully PackageKit) should work.

Thanks. Will try when get back to work.

What about the '@' char in my password. Do I escape it with '\' or just leave it?

I'd be surprised if it worked at all. Consider changing it.

Yup. Didn't work. Need to contact help desk and change the password

Alright, changed the password. Still no go.

This is the error I get in KPackageKit

Code:

E: Error http://extras.ubuntu.com natty/main Sources
407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )
E: Error http://extras.ubuntu.com natty/main i386 Packages
407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )

I get the same error when I sudo apt-get update
