gnss-sdr problems

[Apostolos Kefalas <sv1ljj@raag.org>]

Hello all,

I am trying to configure the gnss-sdr on an newly upgraded Buster and I
have 2 problems.

While trying to run front-end-cal I get the following error:

$ front-end-cal --config_file=front-end-cal.conf
Initializing... Please wait.
Logging will be done at /tmp
Use front-end-cal --log_dir=/path/to/log to change that.
Trying to read ephemeris from SUPL server...
SUPL: Trying to read GPS ephemeris from SUPL server...
ERROR in SUPL client. Please check your Internet connection and SUPL
server configuration
ERROR in SUPL client. Please check your Internet connection and SUPL
server configuration
SUPL: Trying to read Acquisition assistance from SUPL server...
ERROR in SUPL client. Please check your Internet connection and SUPL
server configuration
Failure connecting to SUPL server

Also, while I use the options to enable the build-in bias-t of my RTL-
SDR Blog V3 dongle, it seems that front-end-cal is disabling the bias-t 
just about when it prints this:

Front-end RAW samples captured

Can anyone please verify these before I report a bug?


Thanks
