Hashicorp repository sync error

[Andy Wu]

Sync hashicorp mirror fail with error:

 "summary": "Sync pocket 'release' of series 'hashicorp-jammy' in distribution 'ubuntu'",
    "result_text": "b\"ERROR: Condition 'AA16FCBCA621E701+' not fulfilled for './lists/update-hashicorp-jammy_jammy_InRelease'.\\r\\nSignatures in './lists/update-hashicorp-jammy_jammy_InRelease':\\r\\n'AA16FCBCA621E701' (signed 1970-01-01): bad signature\\r\\nError: Not enough signatures found for remote repository update-hashicorp-jammy (https://apt.releases.hashicorp.com jammy)!\\r\\nThere have been errors!\\r\\n\"",

Step to reproduce:

#Get hashcorp gpg key
wget -O- https://apt.releases.hashicorp.com/gpg | sudo gpg --dearmor -o /usr/share/keyrings/hashicorp-archive-keyring.gpg

#export hashcorp gpg key
gpg --no-default-keyring --keyring /usr/share/keyrings/hashicorp-archive-keyring.gpg --export --armor > hashicorp-public-key.asc

#import hashcorp key to landscape
landscape-api import-gpg-key hashicorp-public-key hashicorp-public-key.asc

#import landscape-mirror key
gpg --batch --gen-key ./landscape_gpg_key_param
landscape-api import-gpg-key mirror-key landscape-gpg-key.asc

# create hashicorp series
landscape-api create-series hashicorp-jammy ubuntu \
  --pockets release \
  --components main \
  --architectures amd64 \
  --gpg-key mirror-key \
  --mirror-gpg-key hashicorp-public-key \
  --mirror-uri https://apt.releases.hashicorp.com \
  --mirror-series jammy

# sync pocket
landscape-api sync-mirror-pocket release hashicorp-jammy ubuntu --json

Then check the activity id will see the gpg key error

There is a support case that talks about the same error,

The case conclude with a workaround to manually setup mirror using reprepro, I wonder if landscape-api can address this issue directly
