I did. and I did run update_indi_core and update_indi_drivers, since the driver for the am5, indi_lx200am5, wasn't present in the download.
So I got the driver I needed, but now the camera drivers crash. I opened a bug by posting here with Stellarmate in the headline.

BTW, the download seems really out-of-date, apt-list --upgradable listed 91 packages needing updates
