Thank you Hui Wang for your quick answer. Could you help me with install and then uninstall procedure? I understand that I have to install all these kernel packages with "sudo dpkg -i". But: 1. What is the order of installation of these packages? 2. After installation how can I switch from current kernel to this new kernel? Currently I use "5.0.0-35-generic #38~18.04.1-Ubuntu SMP Mon Nov 11 09:16:10 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux" 3. What if this new kernel won't boot my computer? Will be there any backup kernel installed? 4. After tests what should I do get back to "stock" kernel?
