can't install latest packer

[ozbillwang]

can't install packer in ubuntu 18.04. The same commands are fine last month

follow the official document: https://developer.hashicorp.com/packer/tutorials/docker-get-started/get-started-install-cli

If I ignore the error (404 Not Found [IP: 18.67.93.76 443]), I can't install the latest packer

$ sudo apt-get update && sudo apt-get install packer
$ packer version
Packer v1.0.4
$  apt-get install -y packer=1.9.1-1

The approach used in the answer here may help: https://discuss.hashicorp.com/t/the-repository-https-apt-releases-hashicorp-com-focal-release-does-not-have-a-release-file/47790/13

Thanks, @sabuncumurat this confirmed the issue.

I finally fixed the issue with another approach.

      sudo apt install -y unzip
      sudo wget https://releases.hashicorp.com/packer/1.11.0/packer_1.11.0_linux_amd64.zip
      sudo unzip packer_1.11.0_linux_amd64.zip
      sudo chmod +x packer
      sudo mv packer /usr/bin/packer
      packer version
