[R-SIG-Mac] arm downloads appear broken

[Prof Brian Ripley]

Your subject line is alarmist -- you only provide any evidence for 1 out 
of > 19000 CRAN packages (and not R itself).

Package RGtk2 was archived in 2021.  The current rattle (5.5.1) does not 
depend on it.  A direct download is available from rattle's CRAN landing 
page.  You have not told us what version of rattle you downloaded nor 
from where.

For me just now R 4.2.2 successfully downloaded

trying URL 
'https://cran.wu.ac.at/bin/macosx/big-sur-arm64/contrib/4.2/rattle_5.5.1.tgz'
