[R-pkg-devel] Update timing of machines on CRAN?

Thanks for your answer.

Unlike Windows Server, which has a long support period, Fedora's 
support period is usually about one year, so it is surprising that the 
old Fedora continues to be used.
And, unlike Windows, Linux uses the distribution standard packages for 
builds, which causes problems like the current Fedora machine that 
continues to use the old Rust.

Hope to see an update soon. Thanks to the staff for maintaining the 
infrastructure.

Hi,

I maintain the prqlr package that uses rustc for compiling, so I 
regularly check the version of Rust on CRAN.
And I have noticed that the Rust version of Fedora has been stagnant 
for the past few months and was wondering why, but upon 
investigation I realized that this is because Fedora on CRAN is 
currently Fedora 36 (out of support in May).

It was quite a surprise to me that out of support Fedora is being 
used, but what is the normal cycle for machines on CRAN to be 
updated? And do we have any way of knowing that schedule?

It depends on the maintainer who cares about these machine, the 
institution where it is hosted, the availability of technical staff, 
and the technical pressure.

I could not even say when the machines I maintain will be updated.
On one version of the retired winbuilder severs we kept the same OS 
version for almost 10 years.
