In general it's best to take a wait and see approach whenever anything new is released. Upgrades from 24.04 to 26.04 usually wait until 26's first point release which should happen sometime this summer

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Dunno. I use Debian, so that stuff just works from day 1.
I only pick up the new LTS when the next non-LTS is released
Don’t know about Ubuntu specifically but for all software I actually want to work, I wait for the first point release upon a major release.
24.04 to 26.04 is a big version jump and sadly they can't check every combination of hardware and software. Some people don't go through the upgrade process and just back up their user data and reinstall when they want to upgrade to a new major release. In my experience, the automatic upgrader is usually fine but occasionally requires me to tweak something on my system.
Missing Nvidia drivers
Ubuntu has a "driver manager" software in the settings which should allow you to install recommended drivers.
Python not compatible with software like Proton VPN
What version are you using and how did you install it? You might be using an older version of their app and the issues are fixed in the latest versions. If you really can't get their app to work, you can go to https://account.protonvpn.com/downloads#openvpn-configuration-files and download an OpenVPN file which you can import in your network settings. It doesn't have all the bells and whistles as their app, but it still allows you to VPN your traffic.
My pc is not welcome in the new Ubuntu world :’(
I mean, isn't Windows notorious for breaking things after an update as well? :P Computers in general are brittle and don't handle change well.
Thank you for all the replies! I will bunker in and wait it out. For the nvidia problems, it’s Steam recommending me drivers which were pre installed on Ubuntu 24, but on 26.02 the were nuked :( I still want to be social and play some games with my friends
sudo apt install nvidia-driver-550-open
Gives all all these errors with dependencies.
Proton VPN I installed from official command lines from their website:
sudo apt install proton-vpn-gnome-desktop
`Error: Unable to satisfy dependencies. Reached two conflicting assignments:

ok back to Ubuntu 24 it is :)
Definitely worth waiting a few weeks and letting the post release patches roll through. I tend to start looking at it for my server upgrade about a month after its officially released, anything earlier is usually under heavy updates. IIRC do-release-upgrade on the server releases typically doesn't even allow upgrades for at least a month.
the daily builds were a trainwreck here leading up to the release, but somehow it all sorted out at the end. my test installs of release (ubuntu, cinnabun, studio, kde) went ok.. with only a few minor issues, like the blueman applet crash in cinnamon.
You are trying to install wrong versions of nvidia drivers and proton app.
For nvidia, use this https://linuxconfig.org/how-to-install-nvidia-drivers-on-ubuntu-26-04
For proton vpn, I assume you are trying to install app meant for 24.04. Do not do that, just search one for 26.04, if it is available.
I installed Steam with flakpak, it works great!! Thank you so much for the help. I can continue using 26.04 <3
Hey, thanks for the reply!
When I start up steam, it says I am missing that specific Nvidia driver with commands to install it. So Maybe Canonical needs to release a new steam client as well?
On the Ubuntu discourse I saw other people had the similiar problem but with newer drivers
Thank you so much.
I always wait for the first service pack release before i upgrade, 26.04.01, should be out in summer, (but i'll probably move to Debian this time anyway).
You've read the stances of all different people. I agree with most and I'm a bit more conservative: I switch to a LTS (even-numbered) release only when its main non-LTS (odd-numbered) upgrade is out; and skip all non-LTS.
