Upgrade Rocky Linux 9 to Rocky Linux 10.1

I started TecMint in 2012 as a side project from my apartment because most Linux content online felt either too academic or copied straight from official docs. So I built the resource I wished existed when I was a junior sysadmin, practical guides written by someone who has actually broken things at 3 AM and figured out why.
Sixteen years later, the site is still here, and so am I. Every article is still tested on a real machine before it gets published. I've never found a better rule.
Every Thursday I share what I just published, what I'm reading, and what I'm building next.
TecMint once reached over 5 million monthly readers at its peak. Over the years, the internet changed, search evolved, and more people began using AI tools to find answers. But the goal never changed: publish Linux tutorials that are tested, practical, and genuinely useful.

I started TecMint in 2012 as a free Linux tutorial site, and for 15+ years it was the best decision I ever made.
By 2022, that side project had grown into a site read by 5 million people every month, with a small team I trusted and readers in 180 countries. Advertisers got eyes on Linux sysadmins, readers got tutorials with no paywall, and I got to spend my days writing. For 15 years it worked, and that's the part I never saw coming.
Then AI search arrived, and I watched the analytics every Monday morning in 2023, and every Monday the line went down. Over two years, monthly traffic had dropped to 1 million. Hosting, the office, author fees, all of it still costs the same. So I had a choice.
I could have paywalled the site, like a lot of others did. I couldn't bring myself to. Sixteen years of free Linux content, and I wasn't going to be the guy who put a wall in front of it. Instead, every article on TecMint stays free, forever. That's why I built Pro TecMint: structured courses and certifications, for $8 a month.
If TecMint has ever saved you a Sunday afternoon, this is how you can give a little back.
"I've been in IT for 26 years as a Network Administrator, primarily in Windows environments. When our storage architect left, I had to step into Linux with very little prior experience. TecMint made the learning curve much smoother. Using the platform, I was able to create a shell script, definitely the most Linux thing I've done so far."
"I passed the RHCSA on my first attempt. The certification course covered every exam topic and the practice questions were exactly what I needed. Six months later, I'm using those same skills at work every day."
"I've been reading TecMint since 2016. The articles are always tested on real systems, you can tell because the commands actually work. I've used it to set up a dozen servers and troubleshoot things I couldn't find documented anywhere else."
"Switched from Windows to Linux two years ago. TecMint was my main reference for the first year. The Bash scripting series saved me hours of manual work. I automated 3 of my daily tasks within a week of reading through it."
"The SSH course is the most thorough I've found anywhere. I've been using SSH for years but still found chapters that filled real gaps in my knowledge. Worth it for the tunneling and key management sections alone."
"I started with Learn Linux in 7 Days as a complete beginner. By day 4 I was comfortable at the command line, and by the end of the week I had SSH access to my first VPS. Clear, practical, and no fluff."
If you read this far, you already know the why. Here's the what.
