Will upgrading from a normal session be complicated, it will update and I won't have to point it the old install boot partition on the regular SATA SSD also in my desktop as I needed to do when I installed 20.04.5 last year? This desktop other than its motherboard is boosted up to the gills and with the video adapter I have running on it and the 8 cores @ 4.2ghz, the 32gb max of ram @ 1866mhz isn't a hindrance still (motherboard supports 2000mhz and 2133mhz of certain brands, but DDR3 at that speed is incredibly expensive if you even manage to find any for sale nowadays, I'll run that machine to the end of the decade it looks like so...I'd just like to know if it will be like when I first installed it on a live session or I won't need to mess around with the other drives, the main SSD drive knows it points to the nvme ssd drive on the x16 pci-e 2.0 adapter at boot, I don't have to tell it again?
Are you sure your details are correct, as that 22.04.3 would make me rather nervous personally.
This (Ubuntu Fridge | Ubuntu 22.04.4 LTS Released) will show the release date of Ubuntu 22.04.4, but installed systems upgraded before the date listed on that page, as the release refers to the ISO release date. I'd expect your release-upgrade tool to likewise state 22.04.4 and not 22.04.3.
Ubuntu MATE 20.04 LTS isn't supported any more, but your base Ubuntu 20.04 LTS system is. The ubuntu-release-upgrader tools however are Ubuntu tools, so are identical for all Ubuntu flavors anyway.
I'll suggest reading the Ubuntu 22.04 LTS release notes and instructions, plus of course Ubuntu MATE 22.04 LTS release instructions, as they'll contain all you should consider. Your biggest issue is the time passed since those instructions where published, but they're still the best places to go.
Just curious, why 22.04? Why not wait a little longer for 24.04.1? If it was me, I would get a new SSD, do a fresh install of 24.04 on the SSD and alongside 20.04.6. Then migrate data over at your leisure. My experience is that fresh installs are much quicker and easier than upgrading.
All the drives in there are brand new, I bought them last summer and I barely touched the system until I got enough money for a video card I wanted.
The system updates offer me 22.04.3, nothing else, I don't want to do a fresh install. It is already basically fresh. The only old thing in there is 1 2TB WD Red HDD which has a lot of critical data (which is backed up on 50gb BD-R's twice for the really important stuff, on many usb sticks for the rest). I have a brand new nvme ssd.
Please, I only want help regarding what I posted about, and it is, will the little trick to boot up from the nvme ssd drive that is on a pci-e 2.0 x16 adapter, which is still worth it with reads at 1850mbps and writes at 1730-1790mbps, it's still better than the regular SATA 6gb/s SSD in there with the 2 tiny partitions at the beginning of the drive allowing me to boot from nvme. I want to know if upgrading live from 20.04.6 will ask me where I want to upgrade to in the following menus if I click on Upgrade and it will not disturb the setup described in the post I linked to, which is the method that is thankfully available to those of us who have motherboards just slightly too old to have nvme ssd slots and have to rely on pci-e adapters and a regular ssd (I can still use the third partition as a data partition, which I will do after upgrading, since 20.04.6 is now not giving me all the updates it could. (to answer jymm here, as of 2 months ago, I have updates that are greyed out which I would need to pay to get, meaning I would need to get Ubuntu Pro or whatever its called, Software Updater brings them up but greys them out).
If it's no issue for the way I boot up a drive my motherboard doesn't see (the nvme ssd on the adapter, but that the linked to configuration of the regular WD Blue SATA SSD which manages to do its magic with the first 2 partitions pointing to the nvme drive where Ubuntu MATE is) to upgrade to what my current OS recommends me to, if I can confirm that without having to start over, then I'll do a regular upgrade again to 24.04.x sometime later. I need to know what I asked for first anyways. Thanks for the advice but that doesn't answer the point of my post. I've always ended up finding great advice here so I'll wait a bit more and then my own research again when I have the time.
Ubuntu Pro is free for personal use. I think your stuff is greyed out because 20.04 has reached end of life, and 22.04 will soon too. That would cause dependency problems. But you are correct if you upgrade to 22.04 and sign up for Ubuntu Pro you will have seven years of support. If you upgrade to 22.04 and then upgrade to 24.04 and sign up for Ubuntu Pro you would then have 10 years of support. No money involved either way. I could be wrong, so maybe others could weigh in on that?
I don't have the same hardware setup, but just yesterday I finally succumbed and decided to go ahead with the upgrade. My notification too, said 22.04.3 but when it was done, I actually had 22.04.4. My setup is somewhat different in that my machine is a server and most of my usage occurs via xrdp or ssh. The upgrade took a while, and several times I had to choose to keep or replace configuration files, like the xrdp-session and systemctl settings files. Since I knowingly modified those to accommodate my usage needs, I chose to keep them.
The only thing that is different is that the default Firefox is now a snap instead of a package. And it didn't work. Fortunately, I was able to remove the snap and install Firefox as a package. I also found that Brave Browser now runs (and updates) very well now, and that's my default browser. Firefox is just there for grins and giggles.
My reasoning for going to 22.04.4 LTS is in the "LTS" portion of the name. 20.04.6 LTS ran nicely for me, once I had the tweaks in place, and I figured the .4 patch of 22.04.4 was now stable enough to not encounter known issues. 24.04 LTS may be in the future, but the only reason I can see to upgrade is that it's supported. If it ain't broke, don't fix it. And my server ain't broke. And now, it's once again supported.
Thanks, mine being just a simple desktop I plan to use as a normal user, I don't foresee any ubuntu server related issues.
I'd really like to know the experience of somebody with a nvme ssd and a regular ssd configured the way in the linked post (and the link within it), if upgrading to a newer version will cause issues with the custom booting process I have to use. I really don't feel like starting over as it scared me enough already at first that it wouldn't work, but when I saw the Ubuntu MATE icon and the insanely fast boot time, I knew the install had worked and I was working from it from the nvme corsair ssd I installed it to, which thankfully the ubuntu (no matter the distro) will see and allow me to install on it, it will boot up on the nvme ssd only if the 2 small partition are created on an ssd that it will boot from but then point the bootloader to the nvme ssd.
As for Ubuntu Pro, I guess I have to subscribe to get those greyed out updates, if it is free, then, problem's solved. I will check it out tonight if I can subscribe, I remember having some Ubuntu program back on 18.04, I forgot the name, it was in the Software Update tabs and also in the systray, making sure I had the latest updates as soon as they were released, but it didn't play nice with Ubuntu MATE, it would crash often, looks like it preferred plain Ubuntu, maybe that is the same thing, it's been a while, I thought I was good too when I saw updates for 20.04 LTS were for 10 years.
So anyway, i'm slightly more confident in going at it, but if somebody who has the same kind of configuration to boot from an nvme ssd adapter by using the trick in my original post (it's well known, duckduckgo spits it out from stackexchange or ubuntu-help to the right and I think google does too, but I stay away from google as much as possible, it's not a big loss these days) and if they succeeded in upgrading their system without it messing up the boot loader, I'd like to hear from it, gpt-4 telling me it will work isn't enough for me.
I`m running 20.04.6 LTS and signed up for Ubuntu Pro and will be getting critical updates for the Main and Universe until 2030. For my particular needs it suits me just fine.
