I am running Elixir 1.10.2:

$ elixir --version
Erlang/OTP 22 [erts-10.5.5] [source] [64-bit] [smp:6:6] [ds:6:6:10] [async-threads:1] [hipe]

Elixir 1.10.2 (compiled with Erlang/OTP 22)
2

This is probably the same issue that was discussed in: Mix deps.update working as mix deps.downgrade

And should be solved by the PR: https://github.com/hexpm/hex/pull/810

But I’m not sure if that PR made it into a hex release already.

I am seeing a similar issue running Elixir 1.12.2, OTP 24.0.5, and Phoenix 1.5.12. When I run mix deps.update --all or mix deps.update phoenix then it first downgrades some dependencies. When I re-run the command, it then upgrades the downgraded dependencies to the latest versions per my mix file settings.

For instance, I just ran mix deps.update phoenix to upgrade from 1.5.12 to 1.5.13 and it downgraded the following:

phoenix 1.5.12 => 1.5.9
phoenix_html 3.0.4 => 3.0.0
plug_cowboy 2.5.2 => 2.3.0

I re-ran the same command mix deps.update phoenix and it upgraded those dependencies as follows:

phoenix 1.5.9 => 1.5.13
phoenix_html 3.0.0 => 3.0.3
plug_cowboy 2.3.0 => 2.5.2

My mix settings for those dependencies are:

...
{:phoenix, "~> 1.5"},
{:phoenix_html, "~> 3.0"},
{:plug_cowboy, "~> 2.2"},
...

Wasn’t sure if I should mention it because it’s already being handled as @axelson noted, but I decided that I’d share just in case. :slight_smile:

UPDATE
I just updated to Elixir 1.12.3 and ran mix deps.update --all and it did not have this “bug” anymore. It updated any outdated dependencies that I had without downgrading any.

So, just thought I’d share this experience and thank you :heart::hugs:
