Update manager gets stuck on a package download

If the update manager gets stuck at a package download and then you can't use "apt-get install" due to errors like dpkg locked and you try rm /var/lib/../../lock and it still does not work then do the following

check the output of this command: 
ps aux | grep http 
This will result in 2 or 3 lines with the second column of each line being the pid of the process if the process is doing its job. If the result is just 1 line, say the last phrase being grep http or something, the updates are not being downloaded/installed. Its safe to kill the update manager 
To do this: 
run: ps aux | grep update and note the pid of the update-manager being the second column after your user name in the 2/3 line list of output. Let the pid of update-manager be pid 
Kill this process by running: 
kill -9 pid 
If operation is not permitted, try with sudo, but take care that you don't kill any other process. Note the pid of update-manager carefully.

Back up slides in Latex

 To have back slides in latex and not screw up the slide numbering, do this.
 1. Add these after your \usepackage{} lines, before \begin{document}
  \newcounter{sauvegardeenumi}
  \newcommand{\asuivre}{\setcounter{sauvegardeenumi}{\theenumi}}
  \newcommand{\suite}{\setcounter{enumi}{\thesauvegardeenumi}} 

2. Then, as below.
\begin{frame}

Your last slide...

\end{frame}
% BACK UP SLIDES
\newcounter{finalframe}
\setcounter{finalframe}{\value{framenumber}}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{frame}
.
.

\end{frame}

\begin{frame}

\end{frame}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\setcounter{framenumber}{\value{finalframe}}
\end{document}

Setting up website on server at IITB

Paste all your files in the public_html folder.

if you can't do that. run
~$ ls -l
and see if have ownership rights on the folder. If you dont, send a email to admin[at]ee[dot]iitb[dot]ac[dot]in and ask them to give you those permissions.

Once you can copy into the folder, you are almost done.
go to - http://www.ee.iitb.ac.in/student/~loginname/

If your CSS file is not loading, then ssh to your account from a terminal, then run
~$ chmod -R 755 public_html

(the -R is very important)

Should be all working now.

Peace.
