Hi Blake,
_Seems_ like it should work.  Running from the directory with the Chimera installer, what is the output of the following commands:

df .
sudo pwd
sudo ls -l
sudo ls -ld .
sudo ls -ld ..

Hi,

My name is Blake, and I'm a postdoc at the U. of Arizona. I'm starting
to use Chimera after using Pymol for a long time, but have had trouble
getting it installed. After downloading the .exe file and changing it
to an executable, here is the error message I get:

blake@omega:~/Desktop$ ls -l chimera-1.2540-linux.exe
-rwxr-xr-x 1 blake blake 97898302 2008-09-10 14:12 chimera-1.2540-linux.exe
blake@omega:~/Desktop$ sudo ./chimera-1.2540-linux.exe
[sudo] password for blake:
sudo: unable to execute ./chimera-1.2540-linux.exe: No such file or directory

There has to be something obvious I'm missing here, correct? I'm
running Ubuntu v. 8.04, if that helps. Thanks, and talk to you soon.

Blake
