:tzdata_release_updater terminating

[madshargreave]

After updating to Elixir 1.2.1 I get the following error continously once i start my server

I use

{:tzdata, "~> 0.5.6"}
{:timex, "~> 0.19.2"},

[error] Task #PID<0.634.0> started from :tzdata_release_updater terminating

Is :logger or :tzdata in your applications list?

[madshargreave]

Yes

[lau]

Strange. It works for me on Elixir 1.2.1.
It shouldn't be necessary but try deleting the _build dir and see if that helps.

[madshargreave]

That actually did the trick, thanks

[lau]

Selv tak. Forresten vil jeg anbefale at bruge https://github.com/lau/calendar ;)

Quick question.. I had this issue with calendar 0.17.2 and elixir 1.3.4. Deleting _build fixed it. Why does that fix this?

[lau]

@jackvnimble I think you might be seeing a different problem. Try deleting deps, then run mix deps.get and you'll might see it again. Solution: use version "~> 0.5.11" to avoid the problem.

[id4ho]

Ah gotcha! I'm stuck to 5.8 through https://github.com/lau/calendar 17.2. Maybe that could be safely bumped? ;)

[lau]

@jackvnimble Try running
mix deps.unlock tzdata and then mix deps.get

You should see tzdata 0.5.11 on the screen and in the mix.lock file0.5.8 should be replaced with 0.5.11.

~> means that higher patch versions are allowed. E.g. for ~> 0.5.8 versions allowed include 0.5.8, 0.5.9, 0.5.11, 0.5.99999 (if 0.5.99999ever gets released ;) ). But not0.6.0nor0.5.7`.
see https://hexdocs.pm/elixir/Version.html

Ah nice! I'll give that a go

What does trigger this error exactly? Like, is it fetching some time zone data on regular basis from time to time?

@lau I had this problem and your fix (below) worked. Thanks!

mix deps.unlock tzdata and then mix deps.get

@lau It's 2020 and the only thing that worked is your fix. Thank you! 🙏🏼

mix deps.unlock tzdata and then mix deps.get

I also removed _build and deps folder before doing this.
