I have to install another Ubuntu OS version maybe 18.04 or any other long-term release. not able to work properly with the current version 19.10.
The problem is I have created some VMs which are very important and they are properly configured to carry out a project, so I don't want to lose those VMs plus the data on the host machine. What would be the better way to install another ubuntu LTS version in this case?
The main problem is wifi on the machine is not working and I'm not able to install any package, update or upgrade to debug the issue or follow the steps posted on help forums with the current version. The link to wireless info script output as suggested here: https://paste.ubuntu.com/p/k39gHmqXpR/
