Sorry for my bad English.
I’m trying to install FreePBX. Downloaded image FreePBX-32bit-6.12.65.iso.
Checked md5. I burn iso to DVD.
After setting up the network, the time and the file system error occurs "UNABLE TO READ GROUP INFORMATION FROM REPOSITORIES. THIS IS A PROBLEM WITH THE GENERATION OF YOUR INSTALL TREE"installation is interrupted.
The network is configured exactly right, I switch to the console and can ping any site and name and address.
My computer is new. Live Ubuntu is running without any problems.
Tell me what to do? I’d like to install FreePBH /
