I have a problem with a program crashing, and I suspect that only the latest version of the package has this problem, so I wish to block this particular version from ever being installed – but I still want to be able to upgrade to future versions.
I think I've read (somewhere, at some point) that the apt system allows for this, but now that I look for it I seem unable to find it.
How would I go about doing this?
P.S. I'm intentionally vague about which package I'm having problems with, as I want to understand this feature of Apt (if indeed it exists), and do not want suggestions specific to the program I'm having problems with.
