I finally decided to install acroread on my Ubuntu machine (since I had to read edits done using it!). Here is a record log.
1. Check your OS version by lsb_release -a, uname -a, gcc -v,...
2. Get the Acrobat Reader version for your OS from:
I use Ubuntu 9.04 on AMD 64-bit. But, since Adobe doesn't have a 64bit installer, I downloaded the Linux - x86 (.deb): AdbeRdr9.1.2-1_i386linux_enu.deb
3. Force install the 32bit package by:
sudo dpkg -i --force-all AdbeRdr9.1.2-1_i386linux_enu.deb
Done. acroread should now be ready.
Finally, a shout-out: don't do it! Go Open! Use evince, or xpdf, or ghostview to read PDFs. Try PDFedit or Kword to edit them.
