I'm trying to install Ubuntu 15.10 on my computer. It has been more than an hour. Is it normal? (I checked the option download the updates during the installation). Is there any way to see logs during the installation to be sure that it's still installing or downloading updates?

This question made me curious so I tested it out by myself and answer is... YES you can.

Go to non-graphical mode by pressing Ctrl+Alt+ F1. Login with default username ubuntu and password is blank. Now you can access /var/log/ and see what's going on.

Since you want to check your installation process, then tail installer debug log:

tail -f /var/log/installer/debug

Switch back to the graphical interface with: Ctrl+Alt+F7.

In the newer Ubuntu releases, if you install using autoinstall config via cloud-init, the installer log is curtin-install.log not debug.

less /var/log/installer/curtin-install.log


tail -f /var/log/installer/curtin-install.log
