Hyphen flashing at the corner to the top left

[J0hn3ch]

After the loading of all device and the boot, the Raspberry Pi 2 Model B is locked in a black screen with hyphen flashing at the corner to the top left. This happens the first time when I install mysql-server through the command:
sudo apt-get install mysql-server;
the installation of this package gave an error 2002 and after reboot the raspberry is locked in this screen.
So, i have decided to format the SD and reinstall last version of raspbian jessie (full image) download from the raspberry official web site, and once I done it, I ONLY UPDATE and UPGRADE the Operating System (without install other things), and at reboot I have the same problem.
Thanks in advance.
Please help me quick because I must a talk at Linux Day of 2016-03-30

Did you use a Raspbian image (not using Noobs)?
If that's the case then you may be running out of disk space.
Did you expand the filesystem?
What is the size of your SD card?

I use Full disk image of Raspbian Jessie, the size of SD is 16GB, How can i expand the filesystem ?

See if Ctrl+Alt+F1 gets you to a terminal screen.
Then use

Code: Select all

sudo raspi-config

and choose the first option.

You could also try to use SSH to log on from another computer and then use the same command.

You don't *have* to, but if you can't open a terminal with a key combination it's a quick and easy way to do it.
