[Bug 1946623] [NEW] Asia/Novosibirsk zoneinfo file contains string 'Asia/Novosibirsk' instead of actual zone info

[Konstantin Boyandin]

Public bug reported:

OS: Ubuntu 18.04.6 LTS
tzdata package: 2021a-2ubuntu0.18.04

Problem: the packages updates file

/usr/share/zoneinfo/Asia/Novosibirsk

with 17-byte file containing string 'Asia/Novosibirsk', instead of
actual zone info file.

The above leads to multiple hard to handle issues with a number of
installed software (e.g. PHP function mktime() begins to segfault
without a reason).

To fix that, I copy a valid file from 20.04.* distribution's latest
tzdata.

The above (mentioned file replacement) happens periodically without any
visible logic in it.
