I'm trying to install Ubuntu 20.04 in a Dell G5-5587, replacing a 100% working Ubuntu 18.04 I tried to install it for scratch and updating from 18.04, with the same problem.
When Ubuntu 20.04 starts, it is stuck in the snap initialization.
When I upgrade from 18.04, It is necessary to wait tens of minutes to pass all snapd steps: Processing snap replacements, refreshing snap core18, installing snap gnome-3-34-1804, etc...
After installing 20.04 from scratch or rebooting after upgrade from 18.04, it is stuck at boot time because snapd stuff, like wait until snapd is fully seeded.
As I say, Ubuntu 18.04.4 is working with no problems at all.
Please, advice. I don't know what to do next.
Note and clues:
- It works if I boot using "Advanced options for Ubuntu" -> "Ubuntu, with Linux 5.4.0-40-generic (rescue mode)" -> "resume".
My problem was related to the GDM3. It used the HDMI port even when no monitor was connected!!!! And in the laptop display, it kept the booting Ubunto logging.
I installed lightdm and working again:
sudo apt install lightdmWhat is incredible is that issues related to GDM3 are constant. I waste the full day installing Ubuntu 20.04 in my son's laptops when the Ubuntu20.04 installation does not take more than 10 minutes.
