Ubuntu stuck in startup after purple login screen and black window with cursor

I tried to update from ubuntu 18 to version 20. During the installation process, it threw some error messages and I had to restart my computer. After this I have not gotten past the purple ubuntu load screen and the black screen with flashing cursor (similar to this question).

From the black screen, I can access the terminal with ctrl + alt + f3. I can login and see my files etc. I can see that the current version is 20.04. But I cant get past the black-screen.

From similar questions/posts to my problem, I have figured out that there probably is some issue with dpkg and gdm3.

If I try sudo dpkg-reconfigure gdm3 i get the error gmd3 is broken or not fully installed. I have tried enabling WaylandEnable=false, but this does nothing after reboot.

If I try sudo dpkg --configure -a or similar, I get this error

dpkg: too many errors, stopping
Error were encounterd while processing:
fontconfig
libpango-1.0-:amd64
gnome-logs
...
...
gnome-power-manager
...
libkf5kiofileweidgets5:amd64
Processing was halted because there were to manny errors.

If I run sudo apt -f install or similar, I always get the error message /usr/bin/dpkg returned an error code (1)

Does anyone know how to fix this? My computer is a Dell Latitude 7400.

Apparently, the upgrade was not completed. Looks like you need to backup personal data and reinstall.

Ok, that was what I was suspecting. Can I reinstall from the terminal or do I need to install from usb?

Sometimes you can complete an interrupted upgrade if the terminal (APT and networking) still works. As you can see, this isn't the case. So, unless others suggest a better solution, do reinstal frum usb.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
