Thank you very much, it works !

I did it but I got the same message.
My Linux box is an amd64 architecture, is the openmodelica package only for 32 bit architecture ?

Hello,

I added the following line in my apt sources.list
       deb http://build.openmodelica.org/apt squeeze stable
I got and installed the secure key
But after the update when I want to install openmodelica I get an error.
       checksum hash inconsistent
The installation failed
Am I missing something ?
Thank you in advance for your answers
