Issue with Arc on Ubuntu

ok managed to get an error:
# tried 10 times to create an uploaded file at /tmp/plug-1536 but failed. Set PLUG_TMPDIR to a directory with write permission

if i manually add sudo chmod -R 777 on the folders that are required then it is working as intended

Under which app does your phoenix application run and under which your reverse-proxy (if you use one)? Who owns the created temp-file/folder? With what permissions is it created originally?

Hey I use nginx fro reverse proxy, and the app is started from the mix release command output.
well i assume root owns it, so my user cannot write and copy from it.
to make it worse the issue is back

I logged out the conn too, and the part of it that has the data to update looks like this:

params: %{
    "_csrf_token" => "SHZoEW4jB1IaRC9uBAsUNTUKTh8QAAAA04+kETRcM3b4ujpZza70Ag==",
    "_method" => "put",
    "_utf8" => "✓",
    "id" => "2",
    "user" => %{
      "avatar" => %Plug.Upload{
        content_type: "image/jpeg",
        filename: "ConceptArt_SneakySneaky_011 (2).jpg",
        path: "/tmp/plug-1536/multipart-1536590148-521595600991125-4"
      },
      "name" => "bencepic",
      "password" => "",
      "role_id" => "1",
      "team_id" => ""
    }
  }

the questionable part here is the avatar since here is shows already that plug.upload, how could i log out the original request with the picture?

other weird thing is that with the get request that gets executed before this is working nicely, doesnt complain about not being logged in - 401

Hey the “solution” i said before seems to be only temporary, do you maybe know a better solution?

Depends on the answers to my questions, which you haven’t given yet.

I’d prefer answers checked in the config or in the filesystem over assumptions.

in the config of the elixir project?

• User and group the phoenix project does run under, shoulb be in your service file to start the service
• User and group the reverse proxy runs under, should be in your service file to start the service
• Owner of the temp folder, just check when its created, also write down permission bits
• Do you run in a SE linux context? (getenforce and sestatus)
