A similar error will happen at runtime for binaries that are dynamically linking with libOSMesa.so.8.0.0:

```
synbol lookup error: /path/to/binary: undefined symbol: glUniform2fv
```

Running `nm` shows that the .so does not have the gl* symbols:

```
$ nm -D /usr/lib/x86_64-linux-gnu/libOSMesa.so.8 | grep gl
                 U _glapi_add_dispatch
                 U _glapi_check_multithread
                 U _glapi_get_context
                 U _glapi_get_dispatch
                 U _glapi_get_dispatch_table_size
                 U _glapi_get_proc_address
                 U _glapi_set_context
                 U _glapi_set_dispatch
                 U _glapi_tls_Context
                 U _glapi_tls_Dispatch
```

Reverting to 18.0.0 works:

```
$ apt-get remove libosmesa6
$ apt-get install libosmesa6=18.0.0~rc5-1ubuntu1 libglapi-mesa=18.0.0~rc5-1ubuntu1
```

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Kan Li (kanli)]

Also facing same issue and downgrading to 18.0.0~rc5-1ubuntu1 version works fine locally. However for heroku hosting (heroku-18 stack), specifying 18.0.0~rc5-1ubuntu1 release in Aptfile doesn't install correctly.

[Timo Aaltonen (tjaalton)]

fixed upstream in 19.0.5

[Timo Aaltonen (tjaalton)]

please test 19.0.8 from ppa:ubuntu-x-swat/updates once it has built

[Kan Li (kanli)]

Tested 19.0.8 from ppa:ubuntu-x-swat/updates locally and the fix works. Any idea when the fix will be available in the ubuntu repo for Bionic release? I haven't found any way to install from ppa on Heroku.

[Timo Aaltonen (tjaalton)]

since this was pre-tested to be fixed by the 19.0.8 update, I'll mark it as a dupe of that bug
