A red triangle with an exclamation mark prompted me to search for the reason my system was not able to install updates. I found a site that said to run:
sudo apt-get update sudo apt-get upgrade
This fixed my issue and the triangle was gone. Then a message popped up and said Ubuntu had a problem. I restarted and Ubuntu hung up on the Ubuntu splash screen. I had made no changes and system had been running fine until today.
It looks like he system may be booting because I am able to access a Confluence server site that I installed. I just cannot get past the Ubuntu splash screens.
I am able to start up from a USB if that helps.
Thanks in advance for any help.
I wanted to add further troubleshooting on my part. I have been able to boot into my original logon screen and desktop. I did this by:
- While booting - hold down shift key to see GRUB menu
- Selected recovery mode
- Select dpkg from recovery menu
- fix broken packages
- restart system
Now I am back to what started this problem. During logon, I see an window that says Ubuntu has experienced an internal error. It also says 'If you notice further problems, try restarting the computer.' I did restart yesterday and that is when my problem started. How do I fix the internal error and not be afraid to restart?
Looks like I have obsolete package versions that I need to upgrade based on the 2nd screen capture.
