Applications slow to launch after 24.04 -> 24.10 and 24.10 -> 25.04 updates

Hoping for some help here. I was running Ubuntu Budgie 24.04 and it was great. No issues. Everything worked as expected. I wanted to update to 25.04, so i first updated to 24.10.

After the 24.10 install, i noticed that almost every application (firefox, Brave, Steam, software updater, budgie welcome, etc.) all take a significant amount of time to launch (>5sec, even up to 20sec). I was hoping that moving to 25.04 would fix the issue, but it had no effect. Almost every app now takes forever to load. Once the app is running, it works fine and is as fast and responsive as expected. But these extensive load times are miserable, and I did not have any such issues with the 24.04 build.

i searched quite a bit before posting here, and found some posts describing the exact same problem on older distributions. unfortunately, none of the prior solutions i found were relevant anymore.

hardware should not be an issue. Ryzen 9 7900x, 32GB ram, NVMe SSD, RTX4070.

plz help. I don’t want to have to go back to windows…

Thank you!

Lets see if this is a system issue or localised to your user account.

Create another account and login and test

Are all applications slow to launch ?

Or only those installed as « snap » ?

To check what’s installed as snap :

snap list --all

Thank you for the responses. hopefully we can get to the bottom of this. FYI, I tried to post a lot more pictures in this response, to help demonstrate what I see from my end, but the New User restrictions limits me to 1 image. I guess I can create additional responses if you want screen shots of specific routines or diagnostics.

With respect to user accounts, the PC has 3 accounts already. I tested this on my account, which has full admin privileges, and my child’s account, which has basic user privileges. I observed the same issue on both accounts. If you feel that creating a new account is still worthwhile, let me know and i can try.

I ran sudo apt update but it returned everything as being up to date.
I ran sudo apt --fix-broken install and it returned no issues.

Here is the Snap list:

I have launched most of the applications on that snap list, and they are all very slow to start. However, I have launched applications not on that list (e.g. Steam, LibreOffice, etc.) and i observe the same issue. However, not everything is slow to launch. I can access the Budgie Desktop settings and system settings without issue. I can launch the budgie screenshot application at full speed (which i launched several times while making this post). I tried the built in mini-games of solitaire and 2048, and those are both as fast as expected. The new Xfce Terminal starts right up without issue as well. hopefully this indicates some common thread between apps that are slow, and those that run as expected.

Here are some other behaviors that I am observing. Hopefully, this helps reveal what the issue could be.

First: I receive the following error message when i launch the Budgie Welcome Center:
This Snap is running on a distro that is unrecognized or on a development release of Ubuntu that has not yet received its snap configuration. Full snap capabilities are unlikely to work

Second: Only since upgrading to 24.10 / 25.04, and with the latest installation of both Google Chrome and Brave Browser, I am unable to download files when the browsers are configured to prompt me to choose the file location. The “choose location” window will appear, but when i click “save” the download is never initiated. I found some mention of this through Google searching, with the following thread describing the same experience. It’s worth noting that when i disable the “choose location” dialog and just have either browser download direct to a pre-determined path, then the download initiates as expected.

Third: When i first updated to 25.04 i was running an old, out-of-date version of Chrome. Last update was probably 6+ months ago. Interestingly, this version of Chrome worked flawlessly. Launched immediately, and had no issues downloading files via the “choose location” dialog. I assumed that Chrome was somehow immune to the issue, so i went ahead and updated to the latest version. Unlike my previous attempts to update Chrome, this time I was able to download a *.deb installation file, which brought me to the Software Center. I had never installed Chrome via this method before, but i clicked “install” and went ahead. The result is that Chrome now suffers from the same slow-launch as Brave and Firefox. Basically, updating from the old version to the new version introduced an issue where there was none previously. As i described in the second point above, the slow launch was accompanied by the inability to save files via the choose location dialog.

Lastly - I searched pretty extensively on this topic before posting here, and found very similar descriptions of this issue, but from older versions of Linux. Here is a post describing my issue, but from back in Ubuntu 19.10:

The recommendation was to run sudo apt-get install appmenu-gtk2-module and then reboot, but when i attempted to do this, it appears that this package is no longer available. I do have appmenu-gtk3-module installed. I validated this by running dpkg -s appmenu-gtk3-module and it provided me with the package installation status. running dpkg -s appmenu-gtk2-module returns no results. I don’t have this package installed.

That’s all the clues I have at the moment. Just to reiterate, i was running 24.04 without any issues, and this problem was definitely introduced when i migrated to 24.10. The issue persisted when i migrated to 25.04. For both migrations, I accepted when asked to remove obsolete packages.

Please download the 25.04 ISO and write to a USB stick. Launch those apps that are slow to start up in a live-session - so firefox, libreoffice. You can also install chrome, logout and login. See what happens with the launch speed.

As I type this, I am running 25.04 direct from a USB drive. Firefox and LibreOffice are now exhibiting normal behavior. Additionally, i no longer receive any error message when launching the Budgie Welcome app, and the launch speed of that app is normal as well.

I installed the Brave browser, and i see no issues. Launch speed is normal and i can use the choose location prompt to download files to an arbitrary folder location.

I downloaded and installed Chrome, but it doesn’t seem to be working at all. It wont launch. However, I’m not sure if that’s a real issue, or just an artifact of running Budgie off a thumb drive.

Overall, the operation of 25.04 is fast and smooth when i run from the USB drive. If my main install ran this well, I wouldn’t be posting on this forum! :smiley:

I personally would spend the half hour to backup what you need and reinstall rather than spending even more time and frustration on the “why” the current install is behaving that way.

That’s fair. The 25.04 image on the USB drive did seem a bit different than my main install. For example, it looks like there is now an “App Center”, but my main install still has the legacy Software Application. Performing a clean install will probably resolve both the issues I know of, and the ones I haven’t encountered yet. I’ll proceed accordingly.

I appreciate your quick feedback. Have a great day.
