I trust that all the 20.10 and 20.04 indi packages (and 21.04?) will be regenerated. Today, I found that indi-bin, libindi-data and libindi1 had been updated. That was insufficient to resolve the issue on the laptop which has only been updated with the binaries.
As pawel-soja indicated on github, if I recompile indi and all its libraries, including 3rd party, everything seems to be working OK.
