Hi,
I am just starting out with ns2 and i am having difficulty installing ns-allinone 2.34 on my ubuntu 10.10.

After extracting ns-allinone 2.34 into the home folder i run the following on the command line and this is what i get.

command: selorm@ubuntu:~$ cd /home/selorm/ns-allinone-2.34

result: selorm@ubuntu:~/ns-allinone-2.34$

command: sudo apt-get install build-essential autoconf automake libxmu-dev gcc-4.3

result: [sudo] password for selorm:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package build-essential
E: Unable to locate package autoconf
E: Unable to locate package automake
E: Unable to locate package libxmu-dev
E: Unable to locate package gcc-4.3
E: Couldn't find any package by regex 'gcc-4.3'
selorm@ubuntu:~/ns-allinone-2.34$

i will be grateful if some one could help out with this challenge.

thank you

Welcome to LQ.

Looks OK. Except that g++-4.1 should be used : sudo apt-get install g++-4.1
No gcc-4.3 is required any more.
( ? Could be used at 10.10 release time, and until a year ago.)

About your "download errors" : Ubuntu 10.10 is unsupported,
some mirrors may not work any more.
But first, please try with a : sudo apt-get update

Which URL are you using in /etc/apt/sources.list ?
( 'cat /etc/apt/sources.list' ).
Like : deb http://extras.ubuntu.com/ubuntu maverick main
( The above mirror still works.)

.

thanks for your reply

i did run sudo apt-get install g++-4.1 but it still gave me an error as below

selorm@ubuntu:~$ sudo apt-get install g++-4.1
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
selorm@ubuntu:~$

# 3.
May be Synaptic is running ? ( Shut it down.)

Or the automatic update is running ? Then just wait until it finishes.

Please do not install any ns (nam ?) from Ubuntu.

The ns package name is "ns2". Is version 2.35, will conflict with ns-2.34,
unless you rename /usr/bin/ns to /usr/bin/ns235.
Some libraries are installed too. Not versions that ns-2.34 can use.
( More possible conflicts.)

Hi,

i am try to install a program(Umbrello) on my ubuntu 10.04
and it keeps giving me the following error.

Requires installation of untrusted packages
The action would require the installation of packages from not authenticated sources.

please help me fix this, it used not to be like this.
i tried installing other software and its the same error.

thank you.

Post #8 : Umbrello http://uml.sourceforge.net/
Happens too with the other Ubuntu versions, when they are old.
I guess they "forget" to replace the old authenticating keys.

Can usually be ignored, when the packages origin from the Ubuntu repo.
