I did an apt purge, then a reinstall - it still does not work, now I'm getting the error (for both indi_asi_ccd and indi_qhy_ccd):
symbol lookup error: indi_asi_ccd:
undefined symbol: _ZN4INDI3CCD9ISNewBLOBEPKcS2_PiS3_PPcS5_S5_i
(this is a different undefined symbol)
Once again, relinking libindidriver.so.1 to libindidriver.so.1.8.5 works.

Was this fix put in the release or do I need to download the new one separately?
