Hi,
I have Ubuntu 9.10 and I need to install "meld" for file comparison.
I did sudo apt-get install meld but the command is failing with this error:
404 Not Found
Failed to fetch 404 Not Found
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
I don't know how to resolve this... my web proxy server is up and running.
Is there any other way to install meld on Ubuntu
please help!!! 
Hi.
That release is no longer supported.
Ubuntu 9.10 (Karmic Koala)
Ubuntu 9.10 (Karmic Koala), released on 29 October 2009,[75] was Canonical's 11th release of Ubuntu. It was supported until April 2011.

You could look at Debian -- Package Search Results -- meld there are 5 instances of meld, but it looks like you'll need some other items, mostly related to python. It also seems like you'll need to download the source package like http://ftp.de.debian.org/debian/pool/main/m/meld/meld_1.1.5.1.orig.tar.gz .. If meld is a "simple" python code, then you may be able to copy it to directory /usr/bin and perhaps it will run.
On my system (Debian lenny), meld is:
% file /usr/bin/meld
/usr/bin/meld: a python script text executable
You might consider updating to a newer release of Ubuntu, or using a program that is similar to meld. However, it looks like the repositories for 9.10 have closed, so that you won't be able to use the package manager to install anything from them.
Best wishes ... cheers, drl
