[modeller_usage] Installation on Ubuntu 18.04

Dear all,

I'm installing Modeller 9.20 on a Ubuntu 18.04.1 LTS. Following the instructions sudo env KEY_MODELLER=myprivatekey dpkg -i modeller_9.20-1_amd64.deb

myprivatekey is my access key)

I get a message in which it reads, extracts and configures the software

But no files or directories are created...

Thanks for your help, Marco
