How to install kafkacat on Fedora

kafkacat is one of my go-to tools when working with Kafka. It’s a producer and consumer, but also a swiss-army knife of debugging and troubleshooting capabilities. So when I built a new Fedora server recently, I needed to get it installed. Unfortunately there’s no pre-packed install available on yum, so here’s how to do it manually.

Note	`kafkacat` is now known as `kcat` (ref). When invoking the command you will need to use `kcat` in place of `kafkacat`.

Using preupgrade to upgrade Fedora 14 to Fedora 15 - proxy errors

When using preupgrade to upgrade an existing Fedora 14 installation to Fedora 15, the following two errors were encountered:

Failed to fetch release info
No groups available in any repository

The box sits on a network behind a proxy out to the web.

The resolution was to make sure that environment variables http_proxy and https_proxy are set: [sourcecode language=“bash”] export http_proxy=http://user:password@proxyserver:port export https_proxy=http://user:password@proxyserver:port [/sourcecode] Make sure you do this from the user from which you run preupgrade.
