[snap] chromium fails to start with "/snap/chromium/1444/usr/lib/chromium-browser/chrome: error while loading shared libraries: libatk-1.0.so.0: cannot open shared object file: No such file or directory"

[Kolargol00]

When starting chromium from the command line, it fails to start with this error:

/snap/chromium/1444/usr/lib/chromium-browser/chrome: error while loading shared libraries: libatk-1.0.so.0: cannot open shared object file: No such file or directory

This is on Ubuntu 20.04.1, upgraded from 18.04.5. However, libatk-1.0.so.0 is installed on the system:

[Olivier Tilloy (osomon)]

It looks like the gnome-3-28-1804 and gtk-common-themes content snaps are not installed, this is what is causing chromium to not find libraries. Those should have been installed automatically when installing chromium.

How did you install chromium? Could it be that you manually uninstalled those content snaps?

[Kolargol00 (kolargol00)]

Thank you for your answer Olivier. That is indeed exactly the case.

The two snaps gnome-3-28-1804 and gtk-common-themes were automatically installed during the upgrade and chromium through the deb transitional package. Then I manually uninstalled gnome-3-28-1804 and gtk-common-themes snaps because I don't see a use for them. The snap CLI never complained about breaking dependencies by doing so.

I thought each snap ships everything it needs and doesn't require other snaps. Where can I see those dependencies then?

[Olivier Tilloy (osomon)]

The dependency system in snapd is intentionally basic and it won't complain when uninstalling a dependency, because it has no way of knowing whether it's strictly required for the snap to work, or simply providing additional capabilities.

The fact that each snap ships everything they need is largely true, but for the exception of the platform snaps (such as gnome-3-28-1804) that contain a set of common libraries typically used by GNOME/GTK applications, which allows de-duplicating and consequently reducing the size of the snaps significantly.

If you're interested in the details, I suggest reading https://snapcraft.io/docs/content-interface.

I am not aware of a generic way to inspect a given snap's dependencies, other than installing it and observing which other content snaps get pulled in.

[Kolargol00 (kolargol00)]

Thank you for your help and explanations. I reinstalled the chromium snap with:

    snap remove chromium
    apt install --reinstall chromium-browser

and now Chromium works again. :)

Under the angle of snapd's limited dependency management, relying on such "hidden", i.e. unenforceable, dependencies for the chromium snap seems like a risky idea...

[Ciro Santilli 六四事件 法轮功 (cirosantilli)]

This seemed to happen to me after running:

```
sudo snap install chromium
sudo snap install pycharm-community --classic
```

but not 100% sure this is a minimal repro on Ubuntu 21.04 snap 2.50.1. The reinstall workaround worked, but I lost all my browser data which is sad.

[Vincent Gerris (vgerris)]

same here, all data gone. what a shit show, like waking up after a car crash feeling fine but no memory. Perhaps devs can consider these kind of things before these things happen.
