Trying the daily build and got this

sudo apt install ./chimerax-daily.deb
many lines....
Processing triggers for man-db (2.12.0-4build2) ...
N: Download is performed unsandboxed as root as file
'/home/murph/Downloads/chimerax-daily.deb' couldn't be accessed by user
'_apt'. - pkgAcquire::Run (13: Permission denied)

I thought installation was unsuccessful*, so I did
su root

0 upgraded, 0 newly installed, 0 to remove and 42 not upgraded.

* But I was wrong...
chimerax-daily works ok
