Update 2020-06-24: problem is solved on server-side. No additional manual actions required.
For those who do not want to wait for a server-side fix, you can patch the MATE Weather library on binary level with single command below:
-
for 64-bit
sudo sed -i 's|https://www.aviationweather.gov/adds/dataserver_current/httpparam|https://www.aviationweather.gov/adds/dataserver1_3/httpparam\x0\x0\x0\x0\x0|' $(readlink -f /usr/lib/x86_64-linux-gnu/libmateweather.so.1) -
for 32-bit
sudo sed -i 's|https://www.aviationweather.gov/adds/dataserver_current/httpparam|https://www.aviationweather.gov/adds/dataserver1_3/httpparam\x0\x0\x0\x0\x0|' $(readlink -f /usr/lib/i386-linux-gnu/libmateweather.so.1)
To revert the patch one can reinstall the corresponding package:
sudo apt-get install --reinstall libmateweather1
