Has supported secure application hosting and reliable server management
I find the GUI to be good in Ubuntu Linux, and I appreciate the open SSH. The fact that it is free since it is open and open-source is why I appreciate it and feel it is secured. We have multiple different kinds of support related to Ubuntu Linux, including official support and other options. I am currently using laptops, desktops, and servers, and Ubuntu Linux supports all these devices. If I need it for Raspberry Pi or something similar, I can download another Linux distribution. Ubuntu Linux is scalable, especially for servers. We prefer using Ubuntu Linux Servers rather than Windows. The biggest advantage of Ubuntu Linux for me is that it is open-source, secured, and scalable.

"There are some drivers that are not there encoded, however, I thought that was pretty normal. They could be more comprehensive."

"Ubuntu Linux needs to improve its stability. I would like it to show the battery percentage at the screen top."
"We don't have any support, so we search for answers online. However, it can sometimes be a little messy to find the information if you have a highly specific question or a strange problem. It would be nice if finding information were a little simpler. Maybe they could have some portal that could point you to where you can find information."
