Products

• VMware Cloud Foundation

Issue/Introduction

• The instructions under the document Installing VCF CLI Using Package Managers are used to setup VCF CLI using Package Managers.
  
  
• The command "curl -fsSL https://packages.broadcom.com/artifactory/vcfcli-debian/tools/keys/BROADCOM-PACKAGING-GPG-RSA-KEY.pub; curl -fsSL https://packages.broadcom.com/artifactory/api/security/keypair/PackagesKey/public | gpg --dearmor -o /etc/apt/keyrings/vcf-archive-keyring.gpg" gives the following error.
  
  gpg: can't create '/etc/apt/keyrings/vcf-archive-keyring.gpg': Permission denied
gpg: no valid OpenPGP data found.
gpg: dearmoring failed: Permission denied


• This happens on a Debian or Ubuntu Virtual Machine.

Environment

VMware Cloud Foundation 9.0

Cause

The current user account does not have the necessary privileges to write files to the /etc/apt/keyrings/ directory. This directory is a system location that requires root privilege for writing.

Resolution

Use "sudo tee" to complete the file writing. Use the below command.

curl -fsSL https://packages.broadcom.com/artifactory/vcfcli-debian/tools/keys/BROADCOM-PACKAGING-GPG-RSA-KEY.pub; curl -fsSL https://packages.broadcom.com/artifactory/api/security/keypair/PackagesKey/public | gpg --dearmor | sudo tee /etc/apt/keyrings/vcf-archive-keyring.gpg >/dev/null

Reason: The 'tee' command is responsible for reading the data and writing it to the system directory.
