[New-bugs-announce] [issue41940] AMD64 Debian root 3.x: tests fail because downloaded files start with: <!DOCTYPE

[STINNER Victor]

New submission from STINNER Victor <vstinner at python.org>:

Why do downloaded files start with <!DOCTYPE?

AMD64 Debian root 3.x:
https://buildbot.python.org/all/#/builders/345/builds/132

5 tests failed:
    test_codecmaps_cn test_codecmaps_jp test_codecmaps_kr
    test_codecmaps_tw test_hashlib

I'm not sure if all failures are download issues.


Examples:

ERROR: test_mapping_file (test.test_codecmaps_kr.TestCP949Map)

AMD64 Debian root 3.9 has similar issues.
