Fail to pull latest commits

#### Description When trying to update my AUR packages with `aura -Aua` I receive an error saying that aura was unable to pull the latest commits. ``` aura :: Proceed? [Y/n] aura :: Saved package state. aura :: Preparing build directories... aura :: Failed to pull latest commits - you may be building an old version! aura :: Building feishin-bin... aura :: Package failed to build, citing: Failed to copy build files. ``` #### Reproduction Steps 1. Open new shell 2. Run `aura -Aua` 3. Proceed with installation 4. See error #### Expected Behavior The AUR packages update as expected. #### Additional Notes - This issue has only cropped up in the last week. I was on vacation and away from my computer and when I came back I was met with this error. - `aura -Syu` works however it throws messages saying it has failed to connect to my pacman mirror (`america.mirror.pkgbuild.com`) but it will successfully update if I do have packages that need upgrading. - Specific message: `error: failed retrieving file 'core.db' from america.mirror.pkgbuild.com : Failed to connect to america.mirror.pkgbuild.com port 443 after 576 ms: Could not connect to server` - I think this might be unrelated but I wanted to include it in case it is relevant. - Question: When running `aura check` one of the messages says something about fixing missing tarballs with `aura -Cm` this just lists the packages that are missing their tarballs is there another step I'm missing here?
