Hi, sorry for the delay.First of all, I'm a newbie on Ubuntu, so...We've managed to get it working now, by reinstalling the whole server again, this time using php5 (not 5.3 or 5.6 or 7). Also, a lot of errors when trying to download packages on ubuntu were solved through firewall and DNS configuration and I think this was causing issues with osticket installation. Oh!, and I discovered that there is an issue when trying to install with a language other than English, the installation gives Error 500.Nevertheless, It's working perfectly now and I'm running some tests and getting to know the environment. So far, so good.You can mark this one as solved.Thank you very much for the quick response.I'll be in touch if some other thing comes up.
