Remedy

Procedure

Download Cloud Pak CLI 3.23.1 or later from https://github.com/IBM/cloud-pak-cli/releases.
Extract the binary file that you downloaded by typing the following command, where <archive_file> is the name of the archive file that you downloaded.
```
tar -xf <archive_file>
```
Modify the permissions of the binary file by typing the following command, where <binary_file> is the name of the Cloud Pak binary file that you extracted from the archive.
```
chmod 755 <binary_file>
```
Move the binary file to the /usr/local/bin directory by typing the following command.
```
mv <binary_file> /usr/local/bin/cloudctl
```
Tip: If this command returns a No such file or directory or Not a directory error message, create the /usr/local/bin directory by typing the following command.
```
sudo mkdir /usr/local/bin
```
Ensure that Cloud Pak CLI is working by typing the following command.
```
cloudctl version
```
