AL2 Limitations
The following topics cover various limitations of AL2, and if they have been resolved in a newer version of Amazon Linux.
yum cannot verify GPG signatures made with GPG subkeys
The version of the rpm package manager in AL2 is from before rpm
added support for verifying package signatures made with GPG subkeys. If you are
creating packages to be compatible with AL2, you will need to ensure you use GPG
signing keys which are compatible with the rpm which is part of AL2
In order to ensure backwards compatibility for existing users, the version of rpm
in AL2 receives only security backports.
The version of rpm in AL2023 includes support for verifying
package signatures made with GPG subkeys.
