Today some important things happened during the day. I updated my laptop’s BIOS, fixed my VPN client (Hiddify), and participated in the monthly meeting at my job
In this post I already mentioned my work results, but today during the monthly meeting there was another discussion about our productivity. The CEO talked about the most important things that happened during the first quarter and said that the quarter was unsuccessful for the company. Honestly, I don’t remember that the main plan was not completed successfully during January, February, and March. In fact, the company achieved about 97% of the plan. Of course, it’s not 100%, but I don’t think it’s that bad. They also reported revenue of more than 110 million rubles.
I also fixed my VPN. Yesterday I mentioned that I started using the work VPN, but it wasn’t fast enough. Especially during the day, I started having more and more issues with it. I didn’t want to just sit and wait until the connection dropped, so I decided to fix my own VPN client instead.
The main issue was with the Hiddify app itself because my version was outdated. I was using version 2.1.1, while version 4.1.1 was already available. However, after installing it on my system (Ubuntu), nothing worked. I kept getting the error “failed to start background core.” I spent a few hours trying to fix it. ChatGPT helped me by suggesting several steps, and I just followed them. In my opinion, the key step was removing the Hiddify configuration files—that’s what actually solved the problem. If you’re curious, I shared the full steps on GitHub.
# Remove user-specific Hiddify configuration files
rm -rf ~/.config/hiddify
# Remove user-specific Hiddify application data
rm -rf ~/.local/share/app.hiddify.com
# Remove root user Hiddify configuration files (in case the app was run with sudo)
sudo rm -rf /root/.config/hiddify
# Remove root user Hiddify application data
sudo rm -rf /root/.local/share/app.hiddify.comBefore fixing my VPN, I updated my laptop’s BIOS firmware and installed other system updates. I thought that maybe I needed to complete all updates first, and then everything would start working properly. Also, the BIOS update notification had been bothering me for the past few weeks. Today I just couldn’t ignore it anymore—it was honestly annoying—so I decided to do everything at my own risk. Why “at my own risk”? Because, in my opinion, Ubuntu can be unstable, and major updates can sometimes break the system. Updating the BIOS feels especially risky—it’s probably the most dangerous update you can do. I also attached some technical instructions.
# Update the system first
sudo apt update && sudo apt upgrade -y
# Start the daemon and refresh the list of available firmware updates
sudo systemctl enable --now fwupd
# Check for available firmware updates
sudo fwupdmgr refresh --force
# Install firmware updates
sudo fwupdmgr update
Today some important things happened during the day. I updated my laptop's BIOS system, fixed my VPN client Hiddify, and participated in the monthly meeting at my job

Today, the CEO talked about the main important things that happened during the first quarter and added that this quarter was unsuccessful for the company. By the way, during January, February, and March, I can't remember that the main plan wasn't finish successfully. But today the main plan was unsuccessful; the company finished about 97%. Of course it's not 100%, but I think it's not bad, they reported that they earned more than 110 million rubles.
I also fixed my VPN. Yesterday I mentioned that I started using my work VPN, and it's not fast enough. Especially during the day, I started feeling some problems with that VPN too. So I couldn't just sit and wait to see what time I'll lose my connection; instead, I managed my own VPN client and fixed it.
The main reason was only with the client app Hiddify, because it was a bit old. I used version 2.1.1 and today alreaady was available version 4.1.1. But when I installed it on my system (Ubuntu), nothing was working, I saw only the error "failed to start background core," and then I spent around a few hours to manage it. But ChatGPT helped me, it gave me some instructions, and I just tried them. In my opinion, that step, which was about removing Hiddify config files, helped me manage the problem. If you're curious about this problem, you can read the full steps here, I shared it on the GitHub page.
Before my VPN fixes, I updated my laptop's BIOS firmware and other updates. I thought maybe I needed to complete all my system updates, and then everything would work. Also, the last few weeks notification about the BIOS firmware update bothered me. But today I couldn't ignore notifications, it just made me angry, so I finished all of them at my own risk. Why at my own risk? Because Ubuntu is such an unstable system in my opinion, each major update can break the system. Especially when you update BIOS firmware, I think it's the most dangerous update on earth. I also attached some technical instructions.
