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."
"The solution is easy to use."
"We have made a switch from Windows and will not be going back as the stability is incredible on an Ubuntu setup."
"Our primary use case is for implementing anything that's open source, like a network monitoring tool or anything connected to network, security or vulnerability scanning, and it can all be done with Linux."
"I like the flexibility, and I work on the command line."
"The tool's valuable feature is its pro security features. I also like the way it serves the infrastructure. The main thing is that each new update or version ensures it comes out with zero vulnerabilities—no high, medium, or low vulnerabilities."
"I definitely recommend Linux Ubuntu."
"Ubuntu Linux is a stable solution."
"We save money by avoiding the need for software purchases and upgrades."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"The portal for the active directory needs to be improved."
"We use and have previously used Windows 10 which is a lot better."
"Ubuntu Linux could improve by having more out-of-the-box functionality for common plug-and-play devices, such as printers. It's sometimes more difficult to plug-and-play printers with Ubuntu Linux. You need to work a bit and make some drivers work. They need to work a bit on plug-and-play devices."
"The product could be compatible with Microsoft."
"The solution could be better integrated with Microsoft."
"The solution could improve by being more user-friendly."
"Stability could be improved."
"I do not think Ubuntu Linux has a robust documentation library."
