Snap Store Not Opening After Ubuntu 24.04 Upgrade? Here’s the Fix

After upgrading to Ubuntu 24.04, many people click the App Center icon — the new home of the Snap Store — and nothing happens. The icon may bounce, a window may flash and close, or the app may simply never appear. Your other programs work fine, which makes the problem feel random.

In reality, this issue usually comes down to a stuck Snap process, leftover data from the older Snap Store, a pending snap update that cannot finish while the app is running, or a broken refresh after the upgrade. The fixes below go from the simplest restart to a clean reinstall of the snap.

Quick Answer

First, fully close the app with snap-store --quit or by killing its process, then reopen it. If that fails, update it from the terminal with sudo snap refresh snap-store. If it still will not open, remove and reinstall it using sudo snap remove snap-store followed by sudo snap install snap-store. Your installed apps are not affected by reinstalling the store itself.

Why the Snap Store Stops Opening After an Upgrade

Ubuntu 24.04 replaced the old Snap Store interface with the App Center, although the underlying snap package is still called snap-store. During a release upgrade, thousands of packages change at once. The store app can be left with an update waiting, a cache built for the older version, or a background process that never closed properly.

Snaps also update themselves in the background. When the store has a refresh pending, Snap may hold it back while the app appears to be running — even if you cannot see any window. That hidden running state is why the icon can seem completely dead.

Signs You Are Facing This Specific Problem

• The App Center icon does nothing, but terminal-installed snaps still work.
• Running snap-store in a terminal shows a message that the snap is already running.
• The app opens once after a reboot, then refuses to open again.
• You see pending updates when you run snap refresh --list.
• The window opens blank or closes within a second or two.

Fix 1: Close the App Properly and Reopen It

Start with the least invasive fix. A background process may be holding the app open invisibly.

1. Open a terminal with Ctrl + Alt + T.
2. Ask the app to quit cleanly: snap-store --quit
3. Wait a few seconds, then check nothing remains: pgrep -a snap-store
4. If a process is still listed, end it: pkill snap-store
5. Wait ten seconds and launch the App Center again from the app grid.

If the store opens normally now, the problem was simply a stuck process. Use the app as usual and watch whether the problem returns after its next automatic update.

Fix 2: Refresh the Snap Store From the Terminal

A pending update is one of the most common causes after an upgrade. The terminal can complete that update even when the graphical store cannot open.

1. Make sure the store is fully closed using the steps above.
2. Check for pending snap updates: snap refresh --list
3. Update only the store: sudo snap refresh snap-store
4. Wait until the terminal confirms the refresh is complete.
5. Reboot your computer once, then open the App Center again.

The reboot matters more than it sounds. Snap mounts and background services are set up at login, and a clean start after a refresh clears leftover states from the upgrade. If the command says the snap has no updates available, move on to the next fix.

Fix 3: Clear the App’s Local Cache

The store keeps a cache and settings in your home folder. After a major upgrade, that data can clash with the new version and cause instant crashes.

1. Close the store completely with pkill snap-store.
2. Back up its settings folder instead of deleting it: mv ~/.config/snap-store ~/.config/snap-store-backup
3. Remove the cached data: rm -rf ~/snap/snap-store/common/.cache
4. Launch the App Center again. It will rebuild fresh settings automatically.
5. Sign in again if needed, and check that your installed apps list loads correctly.

Your installed programs live outside this cache, so clearing it is safe. If everything works, you can delete the backup folder later. If nothing changes, the backup lets you restore your old settings.

Fix 4: Reinstall the Snap Store Snap

If the package itself was damaged during the upgrade, a clean reinstall is the most reliable cure. Reinstalling the store does not remove any apps you installed through it.

1. Open a terminal and close the app: pkill snap-store
2. Remove the store snap: sudo snap remove snap-store
3. Install it again: sudo snap install snap-store
4. Wait for the download and installation to finish completely.
5. Open the App Center from the app grid and give it a little longer than usual on first launch.

The official Snapcraft documentation covers how snap removal and installation work if you want to understand what these commands do behind the scenes. Note that the icon may be labelled App Center while the package name stays snap-store — that is normal on Ubuntu 24.04.

Fix 5: Check for System Updates and Broken Packages

Sometimes the store is not the real problem. An incomplete system upgrade can leave graphics or library packages in a half-configured state, and a graphical app is often the first thing to suffer.

1. Update your package lists: sudo apt update
2. Install all pending system updates: sudo apt upgrade
3. Finish any interrupted configuration: sudo dpkg --configure -a
4. Fix missing dependencies if the system reports any: sudo apt install -f
5. Reboot and test the App Center again.

Keeping the whole system current also helps other snap and desktop problems. Our detailed walkthrough on updating Ubuntu from the terminal step by step explains each of these commands for beginners.

Fix 6: Test With a Terminal Launch to See the Error

If the store still refuses to open, launch it from the terminal so you can read the actual error instead of guessing.

1. Open a terminal.
2. Run: snap-store
3. Read the output. Messages about permissions, themes, or graphics drivers point to the real cause.
4. If you see theme-related errors, switch back to the default Yaru theme in Settings and try again.
5. If you see graphics errors, install any driver offered in Software & Updates under Additional Drivers, then reboot.

Custom icon themes and GTK themes applied before an upgrade are a surprisingly common trigger for store crashes. Returning to the defaults for a test takes one minute and quickly rules this out.

Common Mistakes and Useful Tips

• Refreshing while the app is open: Snap cannot update an app that is running. Always quit the store first, or the refresh stays pending forever and the problem keeps returning.
• Removing snapd itself: Do not remove the whole snapd service to fix one app. That affects every snap on your system and creates a much bigger repair job.
• Skipping the reboot: After a refresh or reinstall, a reboot clears stuck mounts and processes. Skipping it can make a good fix look like it failed.
• Installing a second store: Adding random alternative store packages rarely fixes the root cause and can confuse software sources. Repair the official store first.
• Tip — use the terminal as a backup: While the store is broken, you can still install software with sudo snap install packagename or sudo apt install packagename, so you are never fully stuck.
• Tip — check snap changes: Running snap changes shows recent snap activity and can reveal a refresh that is stuck or was aborted during the upgrade.

Conclusion

When the Snap Store or App Center will not open after upgrading to Ubuntu 24.04, the cause is usually a stuck process, a pending snap refresh, or stale cache data from the old version. Quit the app fully, refresh it from the terminal, and clear its cache before moving to a full reinstall of the snap-store snap. Finish with complete system updates and a reboot. In the vast majority of cases, one of these steps brings the store back, and your installed apps remain untouched throughout.

Frequently Asked Questions

Will reinstalling the Snap Store delete my installed apps?

No. The store is only a front end for browsing and managing software. Apps you installed, whether as snaps or regular packages, stay installed and keep their data when you remove and reinstall the store.

Why is the app called App Center but the package is snap-store?

Ubuntu 24.04 renamed the visible interface to App Center, but the underlying snap package kept its original name, snap-store. Terminal commands still use the package name, while the icon shows the new name.

The store opens but shows a blank window. What should I do?

Close it fully, clear its cache as described in Fix 3, and reopen it. A blank window after an upgrade is usually stale cached data or a theme conflict, and switching to the default Yaru theme helps confirm which one it is.

How long should I wait on the first launch after reinstalling?

Give it up to a minute. The first launch rebuilds indexes and settings. If nothing appears after that and no window opens, launch snap-store from a terminal to read the error message directly.

Can I just use the terminal instead of fixing the store?

Yes, for installing and updating software the terminal works perfectly well. Still, the store is useful for browsing and permissions management, so it is worth applying these fixes when you have a few minutes.
