I have done everything according to "2019-06-05-amd64-17-1-profiles-are-now-stable" news annoucement and after that Steam client does not start with message: libGL error: unable to load driver: radeonsi_dri.so libGL error: driver pointer missing libGL error: failed to load driver: radeonsi libGL error: unable to load driver: radeonsi_dri.so libGL error: driver pointer missing libGL error: failed to load driver: radeonsi libGL error: unable to load driver: swrast_dri.so libGL error: failed to load driver: swrast
somewhat similar issue with nvidia binary. Looks like after upgrading to 17.1 32 bit version of driver does not install. Will open other bug though.
same error even without migrating
