What does 'Ign' , `Get` or 'Hit' mean when running an apt-get update?

When you use apt-get update it verifies if the same update indexes need downloading, if not it does not download the same updated indexes again.

  • Hit means apt checked the timestamps on package list, those match and there are no changes.

  • Ign means there are no changes in the pdiff index file, it wont bother downloading it again.

  • Get means apt checked the timestamps on package list, there were changes and will be downloaded.

Nothing to be scared of, it just means there is no need to download updated indexes again, the ones you have are current.


The correct answer of this question is:

  • Ign means apt tried to download something (such as translation or InRelease file) but didn't find, but that can be ignored, so proceed to the next thing. Because translation can be secondary priority and if InRelease file can't be found, it uses other method for authentication like using Release and Release.gpg pair.

  • Hit means apt needed to download a Release file or InRelease file (because somehow it got deleted) and once it is downloaded, it checked the checksum of the Index file in it and found that the checksum mentioned there matches the checksum of the Package file already downloaded that is in /var/lib/apt/lists. That's why it's a Hit. So, it won't download the Package file again.
