kURL installers will pre-install the krew plugin in your embedded cluster. However, there was an issue in all kURL versions up to v2020.02.05-0.

Here is the symptom:

```
$ kubectl krew upgrade
F0206 19:16:28.346934 26429 root.go:58] failed to update the local index: fetch index at "/opt/replicated/krew/index" failed: command execution failure, output="": exec: "git": executable file not found in $PATH

```

The patch has been provided in the latest versions of kURL, and is only applied to new installations, however there’s a simple way to patch your existing cluster. a) install git, and b) change permissions on a couple of directories.

Here’s the procedure:

a) Install git

For Ubuntu:

```
$ sudo apt-get update
$ sudo apt-get install git -y

```

For RHEL/CentOS/Fedora:

```
$ sudo yum install git

```

b) Change permissions on these of directories:

```
$ sudo chmod -R a+rw /opt/replicated/krew
$ sudo chmod -R a+rw /tmp/krew-downloads

```

And then your krew plugin should work:

```
$ kubectl krew upgrade
Updated the local copy of plugin index.
Skipping plugin support-bundle, it is already on the newest version
Upgraded plugin: krew
Skipping plugin outdated, it is already on the newest version
Skipping plugin preflight, it is already on the newest version
```
