I have an installed ubuntu 22.10 and want to install 23.03 over it, maintaining my /home and desktop

My existing dual boot ubuntu/windows has a separate /home partition, /swap and a /data partition, along with the partitions windows installs.

The above is on one nvme ssd and a second nvme ssd has a /games folder.

If I take the live usb ubuntu option and install 23.04 will I be able to keep my /home partition and desktop?

First you must have backups of Windows & Ubuntu. If you choose the Something Else install option, you choose existing / and existing /home (and must NOT format it), it auto finds swap. Save fstab entry for mounting data partition and add that back into new fstab with new install.

Thank you oldfred, I will do that. Gparted shows an entry /var/snap/firefox/common/host-hunspell partition and I had never seen that before. Will it auto find it too?

Your details are *unclear: Ubuntu had no release in 2023-March (23.03) so are you asking about Ubuntu or some other system. I have a Lubuntu *kinetic* system here that I no longer have need for (already a *lunar* or 23.04 on that box) so I'll re-install *non-destructively* with Lubuntu *mantic* when I have some time as a QA-test install; I expect my data to exist post-install, my *manually installed* apps to also be re-installed (ie. *I'll start `clementine` or a non-default music player & play my music as I assess install*) and my box doesn't have separate /home partition either!

Note: the results will vary with 3rd party applications (*ie. it'll work with the 3rd party that packaged to allow it to work; and fail it the packager didn't consider upgrade!*) and I had less than consistent results with Ubuntu 23.04 Desktop in QA (*I had it both work, and some installs where my additional packages did not auto-reinstall!*) but I suffered no loss of data even on less than ideal QA tests; but I can't recall which installer worked best (23.04 Desktop offers `ubuntu-desktop-installer` & `ubiquity` options!) except I had no issues with *flavors* using `ubiquity` or `calamares`.

FYI: In your comment/question to @oldfred, I ignore any entries relating to *snaps* with regards mounts.. They're used to achieve the *container* model that *snap* packages use; however if I load `gparted` it does **not** see any such re-mount.. but I see multiple if I look via `mount`. Also note: my comment/dup-link is **identical** to what oldfred suggested anyway (*additional add: on a number of non-destructive re-install of Ubuntu Desktop lunar, I enabled universe prior to starting installer; but I can't recall how that interacted with results mentioned in prior comment now sorry*)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
