clean install: you make a backup, nuke the computer, install a fresh upgraded copy of the distro you want from a live usb, copy your data again to the computer.
upgrade: you wait ‘till the distro’ developers release an upgrade you can directly install from your soon to be old distro, you use a command like sudo do-release-upgrade
and why do you upgrade like that?
I follow the official upgrade method. Can’t be bothered to mess around with anything more complicated than that. Besides, the devs probably understand the system better than I do, so there has to be a reason why that is the preferred way.
This is my plan A. I’ll only go to plan B if something goes wrong — which has happened to me a couple times. I tried to upgrade Ubuntu (LTS, I forget which version) years ago, but it failed hard. I still don’t know why. It wasn’t something I could figure out in half an hour, and it wasn’t worth investing more time than that.
Come to think of it, it’s possible all my upgrade woes came down to Nvidia drivers. It was a common problem on Suse (TW), to the point where I pinned my kernel version to avoid the frequent headaches. I’ll try a rolling distro again when I switch to AMD, maybe.
Neither. I use a rolling release distro.
But if I have to use release based distros, I probably would clean install.
Upgrade. It works perfectly fine and when it doesn’t figuring out what’s going on learns me something and several times has resulted in fix commits to the packages.
E: there’s some people saying they do clean installs on Ubuntu. They’re right that ubuntu breaks shit all the time but I’ve solved that by simply not using the bad distros.
Rolling with Gentoo here. Reinstall is not performed even when complete hardware upgrade has been done.
Well, I also use a rolling release distro, my disk died last week so I had to reinstall, so technically FULL hardware update might require a reinstall (safer than copying the root folder from one disk to another since the old one was bad), but yeah, before that I’ve replaced almost every piece of that laptop without a reinstall, even switched from Nvidia to AMD.
Well, yeah. Hard drive failure can force a reinstall. And with laptops there isn’t usually another place for a hard drive, from where to restore the system.
Brainfart, I said laptop meant desktop, obviously didn’t change the GPU on a laptop.
Depends on the distro. On Debian I upgrade cause I know it works well. On Ubuntu I always had issues after an upgrade so I do a clean install don’t use Ubuntu anymore.
