I want to upgrade my Ubuntu 22.04 LTS to Ubuntu 23.04 using an iso file only. I don't want to redownload any thing because my ISP gives me very limited amount of data and it's expensive. I would have no problem to reinstall the system from the iso file if I can somehow save my files and apps.

Does this answer your question? [How to reinstall Ubuntu in the easiest way?](https://askubuntu.com/questions/446102/how-to-reinstall-ubuntu-in-the-easiest-way) Do note (*see my answer*) that it notes your installed apps before erasing system directories, thus the *manually installed* apps you had installed are re-downloaded IF THEY AREN'T ON THE ISO you install from, thus internet is required & many apps maybe downloaded (*as they'll need upgrading too; unless snap packages*)

From ISO? No. https://askubuntu.com/a/1429801/925128, https://askubuntu.com/a/1219470/925128. I would simply reinstall after saving data, then try to see if the home folder was kept or not. As said under here https://askubuntu.com/q/1406798/925128: `choose "other" option and don't format /home partition if it is separate from /, or don't format /`. But I have never tried that. (As said in other comment, apps won't be kept/reinstalled without internet). I would create a new partition and install there the new system, and then delete old one after migrating files from there.

Without internet I don't see how you could keep your apps. If you really need them and you don't have internet, you better DON'T upgrade. What's wrong with 22.04? - Or if you really need 23.04 and your apps, install 23.04 in a new partition and use both systems in multi-boot until you get better internet.

FYI: I perform *package upgrades* on a number of systems via re-installs as it accomplishes two goals; upgrades packages (*I use daily ISOs for the re-install*) at the same time as completing a QA-test with the daily... My checks ensure the *manually installed* packages got re-installed, my data files weren't touched etc.. When a releases reaches EOL (*excluding my primary box*) I use this same method to move the system to a newer release I don't currently have (*usually the next development*) thus perform a *skip* of release.. eg. when 21.10 reached EOL I re-installed and made it 22.10

... thus I'm doing what you want, however the re-install cannot install apps it does not have on the ISO itself.. thus a re-download of all *manually installed* packages not found on the ISO is required.. I don't see any way around that, as it's how the REPAIR or *non-destructive* RE-INSTALL works & ensures everything works (*deb* packages are built for a specific release; if you change release you need new packages or you'll have segfaults due to ABI/API alignment issues). My prior answer tried to detail this (*I have most luck with this with flavors which have universe enabled by default*)

Upgrade from Ubuntu 22.04 to 23.04 using an ISO file.

Create a Live install of 23.04 on your hard drive similar to: https://askubuntu.com/a/1251782/43926

The GRUB menuentry is a little different for 23.4 than for 22.04, Use:

  menuentry "Try or Install ubuntu-23.04-desktop-amd64" {

  loopback loop /ubuntu-23.04-desktop-amd64.iso
  linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/ubuntu-23.04-desktop-amd64.iso quiet splash locale=en_US bootkbd=us console-setup/layoutcode=us noeject --
  initrd (loop)/casper/initrd
  }

Boot the new ISO toram, Install Ubuntu 23.04 in free space.

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.
