I am trying to install Debian on a PowerEdge R830 server. Installation was going smoothly up until the moment I had to pick a mirror. I selected the top choice for mirror in Germany (in the list of German mirrors, that is the first entry in it). I got an error when the installer tried to retrieve the packages.

Since I also entered a proxy I decided to check what the output is on virtual console 4 as per instructions. From the output there I got that the mirror does not provide packages for the Debian Bookworm, which is not a big deal since I can always return and pick another one.

When trying to return to the graphical installer Ctrl+Alt+F1 I got:

All posts I was able to find talk about such an issue on an already installed system (hence the suggestions usually include apt-get install of some sort), which is not the case here.

How can I fix that?

It seems my information was outdated/incorrect.

Ctrl+Alt+F5 returns me to the graphical installer.

The key combination Ctrl+Alt+F1 allows you to switch from the graphical user interface to console 1, also known as TTY1 (Teletype 1).

The key combinations Ctrl+Alt+F2 to Ctrl+Alt+F12 allow you to switch to consoles 2 to 12.

While some of these consoles may display log information, and where some of them represents a separate virtual text console on the system where you can log in and execute commands for interacting with the system.

These consoles are also referred to as TTY2 to TTY12. Typically, the graphical user interface runs on console 7 or console 1 (sometimes on console 2 or 5).

In your case, pressing Ctrl+Alt+F5 will bring you back to the graphical installer.

These key combinations enable you to switch between the graphical user interface and the text-based consoles, which can be useful for performing specific tasks, troubleshooting, or accessing the console when the graphical interface is unresponsive.

  • I selected my post as the answer since it provides straight to the point information. While the whole TTY explanation may be useful, it gives too much information. The actual answer is somewhere at the end in a single sentence. Commented Apr 10, 2024 at 8:22
