This question from an experienced AU member was closed yesterday. I think it was a mistake to close it. The question is clear and the linked duplicate does not fully answer the original.

Direct quote from the original:

"What I want is not only to forbid the package to update but to save it for future installations too. How can I achieve this?"

The duplicate only addresses the issue of locking the current package in the current install. It does not answer the question of how to save the package for a future clean install by reformatting the drive. Drive failure and recovery would be another reason to back up the package.

Can we get this reopened please? It needs a good answer involving copying the deb from /var/cache/apt/archives.
