I have been running CachyOs for some months and I really like it, it is a clean and fast distro based on arch with many DE. You could give it a try on a live usb at least.

I've been using Manjaro for 5+ years with no problem. Manjaro is a rolling distro, and unfortunately there is not enough volunteers in open source community to maintain a bleeding edge rolling distribution that is completely bug free. It is just a matter of personal preference how close to bleeding edge do you want your system to be between Arch, Manjaro, Endeavor, and OpenSUSE. I found that Manjaro is quite useful to have because I run non-FOSS programs like Dropbox, Zotero, MegaSYNC, and MATLAB.

One tips I have is that don't bother to update every other week. There are plenty literal supercomputers running on outdated Linux OS or stable distro releases like Fedora. Linux by default is already more secure. Just because there are updates available doesn't mean one should do it, unless you need the bleeding edge updates due to your line of work. I thought we install Linux to run away from annoying Windows updates. If you update Manjaro like every 6 months or so, it is pretty unlikely (statistically) that you get a bad update.

If you want to go back to something based on debian, consider PopOS!

Looks like Syncterm is available in the AUR.

Open up Pamac, your graphical package manager, and click on the 3 lines in the top-right corner.

At the bottom of the window, click Third-Party, then enable AUR support.

Search for Syncterm and it should show up now.

Getting packages not in official repositories is significantly easier in Arch-based distros like Manjaro than Debian-based distros or RPM-based distros. It's a major reason why I never use either for personal computing.

Disclaimer: I've been a Manjaro user for 3+ and seeing people recommend Fedora over Manjaro just further cements in my mind that the vast majority of people in this community are not worth listening to.

Do you notice how many people in this thread are recommending you different distros instead of simple instructions on how to get Syncterm to work with Manjaro?
