[Solved] Cannot load Zebra3 & Repro-1 on Bitwig due to libxcb-keysyms.so.1 something – u-he Linux support Forum

This is strange. A couple months ago I could install and load Zebra3 beta and and Repro1 without problems on Bitwig 6 (some beta). I have started fresh with a new Ubuntu 25.10 installation, a new AMD graphics card (if it matters, was Nvidia), and Bitwig 6 beta 15. I have just installed the same U-he plugins using the installer, the clap and vst3 files are in their respective folders but… Bitwig cannot scan them, they don’t show up as available plugins. If I use Bitwig’s browser to find them, they are there, but when I click on them this error message (that I had never seen before) appears:

I have searched online and there are just a couple of reports of this error, from years ago, and without clear steps to fix the problem.

Since I’m using a beta version of Bitwig, I thought about installing another clap plugin just in case. I just went for “ANINA – Free spectral shaping plugin”, it’s one of those plugins that you just need to move the clap file to the .clap folder. Bitwig has recognized immediately and it can load it without problems.

Any idea about what might be happening?
