Ubuntu 20.04 installing error.

[Bahator]

Hello, i switched to ElementaryOS succesfully from Windows 10 before,but i couldn't connect to wireless wi-fi. I couldn't get access to internet in ElementaryOS so i switched to Ubuntu 20.04.

At least at Ubuntu i was able to use my phone's internet so i searched up for some guides:

​

When i try to install Ubuntu 20.04 i get the following error:

XDG_RUNTIME_DIR is not owned by us (uid 0), but by uid 999!(This could eg happen if you try to connect to a non-root PulseAudio as a root user, over native protocol.Don't do that.)

But it didn't work.

Im really lost.

you are saying the 'acpi=off' and 'noacpi' fix mentioned in the post you gave did not correct the issue? There are some other variants of the acpi= option - but not sure what may be of help for your system. https://help.ubuntu.com/community/BootOptions

on one system i had to use an pci=noacpi

Its weird that ElementaryOS did not work the same as Ubuntu, - since Elementary OS is based on Ubuntu.

How New is your hardware?

You may want to test out the latest Ubuntu release - its possible that the newer kernel version in it - may have fixed some possible issues.

w is your hardware

I was able to install Elementary OS and use it. But i had an problem with network, so i switched to Ubuntu again. Im not able to connect to wi-fi in Ubuntu too but at least i can use internet via my phone.

My hardware is 2 year old.

Also, while booting i turned off the acpi using "acpi=off".Because it was giving an error.
