"arm64" and "aarch64" refer to the same thing. Go and Debian-based distros use "arm64" to specify support for 64-bit arm, while RHEL/CentOS-based distros use the 'aarch64' value. Historically, our publication scripts appear to be using the Go-lang arch value of 'arch64' versus the RHEL/CentOS 'aarch64' value for the package architecture. It is more accurate to publish the RPMs with the aarch64 value and it is something we are looking into.

As far as 1.20.0 not showing up, I have confirmed that as well:

I was able to download the RPM and install it just fine:

@codyshepherd any thoughts on why this might be?

[jpalomaki]

@powersj Thanks for the quick response.

I don't have much experience with yum repos, but should the timestamps in this file be more recent: https://repos.influxdata.com/rhel/7/arm64/stable/repodata/repomd.xml?

Currently it shows <timestamp>1626296927</timestamp> which'd be Wed Jul 14 2021 21:08:47 GMT+0000?

[powersj]

Ah yes! that would explain why 1.19.2, 1.19.3, and 1.20.0 are not showing up. Let me get with the team to see how we update that file.

[codyshepherd]

This is very likely due to changes made to the package repo to support correct aarch64 packaging for rpms. I've proposed a fix to bring Telegraf in line with this reorganization.

[jpalomaki]

@codyshepherd All right, let me know when the fix is rolled out (Iooks like the links point to a private repo so I can't track it myself).

[jpalomaki]

@codyshepherd @powersj FWIW, I can now install 1.20.2 via said yum repo

[powersj]

@jpalomaki Thanks for letting us know. I manually kicked off the update process last week. We just landed some automation to ensure that the older arm64 folder and the proper aarch64 folders get updated in the future. I'm going to go ahead and close this, but do feel free to reach out if you see any issues in the future!

Thanks again!
