Maciej Szymkiewicz commented on SPARK-38174:
--------------------------------------------
I also compared the last failing log and the next that passed
(https://github.com/apache/spark/runs/5144322617?check_suite_focus=true), but
nothing really stands out, and virtual image version is still 20220207.1.
Histogram looks unremarkable and, since files are written for each build, we
can reject "later version" as a plausible explanation.
It seems like the issue can arise if files were somehow corrupt, but I cannot
see why on this particular one.
It seems like it failed pretty deep into core R utilities
{code}
45. base:::as.data.frame(read_CRAN_object(CRAN_baseurl_for_web_area() ...
46. tools:::read_CRAN_object(CRAN_baseurl_for_web_area(), "web/packag ...
47. base:::readRDS(con)
48. base:::.handleSimpleError(function (err) ...
49. pkgdown:::h(simpleError(msg, call))
50. rlang:::abort(msg, parent = err)
51. rlang:::signal_abort(cnd, .file)
52. base:::signalCondition(cnd)
53. (function (e) ...
{code}
and I none of the packages that we install specifically for docs R builds are
likely to the culprit ‒ these are mostly font utils.
Doesn't seem like CRAN deb repos provide changelogs, so I am not sure if
something changed there.
I guess it is something to monitor, unless anyone has any other ideas where to
look for the source of the problem.
