Installation failure of packer in Rhel 7

[vanshikw]

When installing packer using the below lines, I am getting error

Lines:
echo "Adding Packer to the image"
sudo yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo
sudo yum -y install packer || exit 1

11:01:21 azure-arm:
11:01:21 azure-arm: One of the configured repositories failed (Hashicorp Stable - x86_64),
11:01:21 azure-arm: and yum doesn't have enough cached data to continue. At this point the only
11:01:21 azure-arm: safe thing yum can do is fail. There are a few ways to work "fix" this:
11:01:21 azure-arm:
11:01:21 azure-arm: 1. Contact the upstream for the repository and get them to fix the problem.
11:01:21 azure-arm:
11:01:21 azure-arm: 2. Reconfigure the baseurl/etc. for the repository, to point to a working
11:01:21 azure-arm: upstream. This is most often useful if you are using a newer
11:01:21 azure-arm: distribution release than is supported by the repository (and the
11:01:21 azure-arm: packages for the previous distribution release still work).
11:01:21 azure-arm:
11:01:21 azure-arm: 3. Run the command with the repository temporarily disabled
11:01:21 azure-arm: yum --disablerepo=hashicorp ...
11:01:21 azure-arm:
11:01:21 azure-arm: 4. Disable the repository permanently, so yum won't use it by default. Yum
11:01:21 azure-arm: will then just ignore the repository until you permanently enable it
11:01:22 azure-arm: again or use --enablerepo for temporary usage:
11:01:22 azure-arm:
11:01:22 azure-arm: yum-config-manager --disable hashicorp
11:01:22 azure-arm: or
11:01:22 azure-arm: subscription-manager repos --disable=hashicorp
11:01:22 azure-arm:
11:01:22 azure-arm: 5. Configure the failing repository to be skipped, if it is unavailable.
11:01:22 azure-arm: Note that yum will try to contact the repo. when it runs most commands,
11:01:22 azure-arm: so will have to try and fail each time (and thus. yum will be be much
11:01:22 azure-arm: slower). If it is a very temporary problem though, this is often a nice
11:01:22 azure-arm: compromise:
11:01:22 azure-arm:
11:01:22 azure-arm: yum-config-manager --save --setopt=hashicorp.skip_if_unavailable=true
11:01:22 azure-arm:
11:01:22 azure-arm: failure: repodata/repomd.xml from hashicorp: [Errno 256] No more mirrors to try.

How to install packer now?

[nywilken]

Hi @vanshikw thanks for reaching out. It sounds like you might be running into an issue with the recent changes made to HashiCorp's Linux package distributions. In October of last year, the RHEL/Centos 7 aliases such as 7Server, 7Workstation, 7.7, 7.8, 7.9 were consolidated into a single repository for RHEL 7. Last week all the EoL linux distributions were removed from the repository and I assume the removal of aliases were in full effect.

Unfortunately, this means that practitioners need to change the releasever variable within the repo baseurl to 7 as opposed to 7Server or any other variant. The consolidation of alias also occurred for RHEL/Centos 8.

That being said, you have two options to install Packer on RHEL 7.

1. Via yum you can update the yum subscription for HashiCorp to use RHEL/7. See example below.

[hashicorp]
baseurl = https://rpm.releases.hashicorp.com/RHEL/7/aarch64/stable
cachedir = /var/cache/yum/aarch64/7/hashicorp
gpgcadir = /var/lib/yum/repos/aarch64/7/hashicorp/gpgcadir
gpgdir = /var/lib/yum/repos/aarch64/7/hashicorp/gpgdir
gpgkey = https://rpm.releases.hashicorp.com/gpg
hdrdir = /var/cache/yum/aarch64/7/hashicorp/headers
persistdir = /var/lib/yum/repos/aarch64/7/hashicorp
pkgdir = /var/cache/yum/aarch64/7/hashicorp/packages

2. You can manually download the RHEL 7 binaries for your flavor of RHEl 7 at https://archive.releases.hashicorp.com/RHEL/

Please try updating your yum configuration and try again. I will keep this issue open until you report back to ensure you can get Packer installed correctly.
