APT Repository

The ARCsoft APT repository serves packages we can use on Ubuntu servers. It may be extended to include RPMs and Python packages as well.

• ARCsoft APT repo sources package
• ARCsoft APT repo sources package signature

To verify the downloaded package, please download both the above and then:

• Import the ARCsoft GPG key on our About page by copying it and pasting it into the following:

  gpg --import
  

  Hit Ctrl-D to close off the input when pasted.
• Verify the signature with:

  gpg --verify arcsoft-repo_0.1.1_all.deb.sig
  

You should see something like:

gpg: assuming signed data in 'arcsoft-repo_0.1.1_all.deb'
