Error installing on Ubuntu/Debian with a version other than latest about ansible-telegraf HOT 8 OPEN

@sk1u You are using Debian or Ubuntu as well?

It seems the apt repository containing Telegraf only contains the latest available version. With every new Telegraf version, the old one is removed from their apt repository and thus new installation fails.

I've created an issue on the Telegraf project:

influxdata/telegraf#5685

from ansible-telegraf.

Just wanted to chip in, that using telegraf_agent_version only solves half the problem, as running the role again will fail if a new version comes out. It would be awesome if there was a way to "force" an update to the latest "minor/patch" version (e.g today it's 1.10.4).

I had the previous patch version before, and when I ran the role I saw this:

Do note that I was able to run apt install telegraf manually just fine, and this unblocked me. Maybe we should consider using some of the parameters of the apt_module ? Such as autoclean, force_apt_get, update_cache, etc ... if either of these works, we can hide it behind an optional toggle for extra safety / backward-compat.

hm, with telegraf_agent_version: 1.10.2 everything works, but with default does not

from ansible-telegraf.

I have experienced the same issue.
Using default telegraf_agent_version yields the same error message, even if I set it to telegraf_agent_version: 1.10.2, I still get failed: E: Version '1.10.2-1' for 'telegraf' was not found.

The workaround in my case was to use instead telegraf_agent_package_state: latest as per docs.
Would be nice however to freeze the Telegraf version.

That is right, it is a Debian 9 host.

Your explanation makes sense, thank you for that.

from ansible-telegraf.

This is still happening, even on "online" installs. This entire step is contradictory (the name is "==latest", the when is "!= latest"). It always sets the name, unless 'latest' is not set...

When combined with this, you can only use the defaults (which are a minor version behind 1.10 vs 1.11.5) because the destination "telegraf_agent_package" needs to be a full file path.

from ansible-telegraf.

When I set my version to 1.11.5 the "telegraf_agent_package" variable gets set to "telegraf=1.11.5-1" which is not a path as required by the get_url module.

These could be a typo:
Maybe this should be "== latest"?

Changing the conditional to match the task description fixed my problems (per the pull request I created). This pull request is a simple 1 character change which allows most installs to work, it should be an easy approval:
#108
