libgles2 dependency version mismatch error

[Bharat]

libgles2 has listed libglvnd0 (= 1.3.1-1) as its dependency but apt is trying to install version (= 1.3.1-1ubuntu0.20.04.1).

This is the error I get when doing `sudo apt install liblges2`:

```
The following packages have unmet dependencies:
 libgles2 : Depends: libglvnd0 (= 1.3.1-1) but 1.3.1-1ubuntu0.20.04.1 is to be installed
E: Unable to correct problems, you have held broken packages.
```

I'm using Xubuntu 20.04.1.

UPDATE:

I ran `apt-cache policy libgles2` and found out that apt is actually trying to install libgles2 1.3.1-1 instead of 1.3.1-1ubuntu0.20.04.01. So that's why the dependency error.

So, I guess it's a problem with apt. I've fixed it by manually installing the correct version. But I wonder what was causing it.

Sorry for posting this in haste.

you hadn't installed updates, that's why

Can you please specify which updates? I just installed this OS two days ago and ran `apt dist-upgrade` command afterwards and also updated other apps from Software Updater.

Or do you mean some other sort of updates?

Thanks.

libglvnd0 and libgles2 are built from the same source, it seems weird that one would be updated and not the other one.. and the new version has been in focal-updates since mid-August
