With a recent update of ArchLinux, I got the error that `libtbb.so.2` cannot be found. With some researching, it seems it is superseded by `libtbb.so.12`, so I linked it like this:
```auto
ln -s /usr/lib/libtbb.so.12 /usr/lib/libtbb.so.2
```
But this result in the following error:
> /opt/paraview/bin/pvserver: symbol lookup error: /opt/paraview/bin/…/lib/libvtkCommonCore-pv5.9.so.1: undefined symbol: \_ZTIN3tbb4taskE
>
> [1] + 4961 exit 127 /opt/paraview/bin/pvserver
Is anyone facing similar issues?

The ArchLinux package is working great here, make sure your system is up to date.
In any case, not a ParaView issue, but a ArchLinux package issue.

Okay. Solved. I was using the paraview-opt version and maybe my modifications broke it. Installed the `community/paraview` version `5.9.1-6`, which is working fine ATM.
