There are a few areas where I think Ubuntu Linux could be improved. The first one is hardware compatibility. Sometimes when we get a new machine, certain hardware like Wi-Fi cards, graphics cards, or printers do not work straight away out of the box. You have to manually find and install drivers, which can be frustrating, especially for people who are not very technical. Another area is the graphical user interface, or GUI, and desktop experience. While Ubuntu Linux has improved a lot in this area, it still does not feel as polished or as smooth as Windows or macOS for non-technical users. If Ubuntu Linux wants to attract more everyday users, that is an area they need to keep improving.On the software compatibility side, one of our biggest frustrations is that some industry-standard tools simply do not have native Linux versions. For example, tools such as Microsoft Office, Adobe Creative Suite, and some specialized enterprise software just do not run natively on Ubuntu Linux. We have to use workarounds such as running Windows in a virtual machine or using a web-based alternative, which is not always ideal. Additionally, when it comes to vendor support, sometimes when we reach out to third-party software vendors for technical support, they do not officially support Linux. We are kind of on our own figuring things out. That can be really frustrating when you are dealing with a critical issue and the vendor just says they do not support Linux. Another thing is enterprise solution integration. Some enterprise tools that businesses commonly use, such as certain ERP systems or CRM platforms, either do not have a Linux version, or their Linux versions are not as feature-rich or well-maintained as the Windows counterparts.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Flatcar's support is good, and the version I am using is stable and allows us to make needed changes."
"It's faster than Windows."
"In terms of security, I am satisfied with Ubuntu Linux and I can rely on its security features more than I can with Windows."
"Doesn't require significant manual configuration."
"I think Ubuntu's main strength, as opposed to using the other Linuxes, has been its ability to encourage user feedback."
"I love using it; it is the best-supported one by the community, and I still recommend it to anybody who asks me, "What should I do here?""
"I switched for stability reasons."
"We can easily customize the NTS Client code."
"The solution has a very good graphical user interface."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"They can make it user-friendly. It is not totally user-friendly."
"People with a Windows background may not find the solution's user interface user-friendly."
"If you´re looking for a robust implementation, then go with AWS."
"There is not a lot of support for applications in Ubuntu Linux. In the industry, most of the applications work for Windows and Mac. There should be better integration with applications in the future."
"It is an open-source tool, and it doesn't have any support. If there is an issue with the implementation of a feature, such as clustering, I am not sure how to resolve it and get support for it. The stability of the vendor packages also impacts the stability of this solution. When vendor packages are unstable, or any packages are broken, they also impact Ubuntu Linux. It is very hard to resolve an issue related to unstable vendor packages."
"I think Ubuntu is not that secure."
"The solution could improve by being more user-friendly, you need to know how to use the command-line interface which you might not understand."
"It's a scalable product, but not the best."
