I want to upgrade my 17.3 to 18.1 but my OS is not allowing me to upgrade. People I asked and even Zorin themselves in their website lists customization from third party as one of the reasons.
I think my Zorin is as vanilla as can be and only installed software from APT, or flatpak. No customization at all has been made since its a new install and I like the default zorin look. What can I do?
I think you can copy your packages using terminal commands (for APT and Flatpak), as well as the /config and /var folders containing your system and package settings—even your accounts will be preserved. You can simply move anything else important to another drive or a flash drive and then install the new system.
Thanks for your time; I might have missed a detail or two, but this is exactly how I do it—afterward, I just reinstall my programs using a script based on those files.
