Hoi Kees,could you please upload a new version of Metar before March 2nd as the Buster hard freeze is coming up March 12 and the current delay is 10 days for packages to transition to testing.
Bug #921840 is the related Debian bug.If you currently don't have the time, I can NMU but you have everything ready in your Github repo already.
Vriendelijke groet, Daniel
