leapsecond file ('/usr/share/zoneinfo/leap-seconds.list'): will expire in less than 27 days
I quickly grepped my DEBIAN-USER mailing-list file but did not find any
leapsecond in it, thus this message.
I get this error on all of my buster machines although I think they are
Dec 1 09:34:39 virtual ntpd: leapsecond file ('/usr/share/zoneinfo/leap-seconds.list'): will expire in less than 27 days
A quick Internet search shows this:
Apparently, the Debian distributed file will expire on 2020-12-28.
However, it seems the next Debian point release scheduled on 2020-12-05
contains an update for tzdata, so it should be fixed then.
