I have new laptop Lenovo ideapad gaming 3 15arh05 with ryzen 7 4800H and Nvidia GTX 1650ti. For work I need to use Ubuntu 18 with Ros Melodic but I am unable to install this system, I tried Ubuntu 20 and it worked perfectly. I tried with diffrent options like secure boot, uefi/legacy. When I choose TRY UBUNTU, I get errors:

pci ... AMD-VI: Unable to read/write to IOMMU perf counter
integrity: Problem loading X.509 certificate -65
nouveau DRM: failed to create kernel channel, -22
sd [sda] No Caching mode page found
sd [sda] Assuming drive cache: write through
Then I see purple screen and get over 100 errors
[FAILED] Failed to start User Manager for UID 121.
[OK] Started Session c(numbers from 5 to 99) of user gdm.
[OK] Removed slice User Slice of gdm.
[OK] Created slice User Slice of gdm.

Then process freezes and I need to reboot laptop.

I have fought for 6 days. Maybe I don't see everything and I do mistake somewhere or should I install Ubuntu 20 and somehow try to install Ros Melodic?

Ubuntu Core 20 is a very different product to Ubuntu 18.04 LTS. Ubuntu has had *snap* only products that are identified by the use of *year* only since 2016, but are you sure you're comparing Ubuntu Core 20 & Ubuntu 18.04 LTS as they are different products? Please clarify and correct. (18 & 18.04.5 are likewise different Ubuntu products)

You're laptop is probably too new for the kernel provided with the setup of Ubuntu 18.04. The two simplest solution I see :

  1. Use the ROS provided for ubuntu 20.04 http://wiki.ros.org/noetic/Installation

  2. Install ubuntu 18.04 as a virtual machine with gnome-boxes or virtualbox

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.
