From what I can gather, it could be a few different bugs. Please read and follow the instructions. I listed them in descending order from easiest to hardest.
1. Updates
Problem: If there's ever an issue, by habit, updating and upgrading might help it, especially with new releases having bugs.
solution: Run in your terminal. autoremove will remove any unused packages files. Might be an incompatibility issue with 20.04 that you weren't even aware of.
Kod: Markera allt
sudo apt-get update
sudo apt-get upgrade
sudo apt-get autoremove
2. GRUB bootloader
Problem: the GRUB boot loader may have been overwritten (MBP), preventing Ubuntu from booting
Solution: check is whether you can access the GRUB2 boot loader. Boot your computer while holding the Shift key. If you see a menu with a list of operating systems appear, you’ve accessed the GRUB boot loader.
If you see the Grub boot menu: Select the “Advanced options for Ubuntu” then select the “Ubuntu (recovery mode)” option. Checkout the 1st URL in the appendix for which menu option to use.
If you don't see the Grub boot menu: Make sure you have working wifi then following below.
If you have the media you installed Ubuntu from, insert it into your computer, restart, and boot from the removable drive. If you don't, download a Ubuntu live CD and burn it to a disc or create a bootable USB flash drive.
When Ubuntu boots, click "Try Ubuntu" to get a usable desktop environment.
Open a Terminal window from the Dash and run the following commands:
This will install and launch Boot Repair to scan your system.
Kod: Markera allt
sudo apt-add-repository ppa:yannubuntu/boot-repair
sudo apt update
sudo apt install -y boot-repair
boot-repair
Choose recommended repair and follow the instructions.
Restart your computer. It should boot up normally if that was the issue.
Note: if you want the original walk-through or another way check out the 2nd URL in the appendix.
3. Reinstall Ubuntu while keeping files and programs
Problem: Might be a problem with Ubuntu 20.04. I currently use 20.04 version without this bug. It might be that it wasn't downloaded properly.
Solution: Follows instructions from the 2nd and 3rd URL in the appendix. From the least aggressive to the most. Follow these terminal commands: to update the snap store to was recently switched.
Kod: Markera allt
sudo apt update
gnome-software
// if you don't have it then run:
sudo apt install gnome-software
to reinstall Ubuntu software -shouldn’t erase your files but if you want, make a backup of your files
Kod: Markera allt
sudo apt install --reinstall ubuntu-software
