 This is a result of 
 https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/35567 
 upstream. I already opened 
 https://gitlab.freedesktop.org/mesa/mesa/-/issues/13745 about this. 
  
 Short term solution suggested here: 
 https://gitlab.freedesktop.org/mesa/mesa/-/issues/13745#note_3065256 
  
      when you get to packaging post-!35567 versions of Mesa for 
      Debian/Ubuntu, you'll need at least a stopgap solution to this. 
      Since the packaging is already running sed on the JSON manifest to 
      make the library_path architecture-independent and implement approach 
      (2.), probably the easiest way in the short term is to delete the 
      line that sets the library architecture (/library_arch/d) at the 
      same time, effectively undoing !35567 (merged). 
  
 I'll try to turn that into a concrete patch. 
  
 Or alternatively, reverting !35567 should do it. 
  
 The long term answer is to talk to upstream on 
 https://gitlab.freedesktop.org/mesa/mesa/-/issues/13745 and figure out 
 what long-term solution to https://bugs.debian.org/980148 they want. 
 There seems to be rough consensus that what we're doing is "the right 
 shape", but it'll likely need some more code upstream for developer 
 use-cases.
