Should I allow packages to be downgraded by synaptic?

  • 772

On synaptic, I want to install dkpg-dev, but synaptic need to downgrade libdkpg-perl for this. Is it a good idea to allow that or I will run into broken packages issues. What rule of thumb do you use in this cases ? I have a newly installed Ubuntu 14.04. How come I run into this ? Thank you. .

Here is my sources.list:

deb-src http://us.archive.ubuntu.com/ubuntu/ trusty main restricted

Actually, I re-installed libdkpg-perl. It was

"installed version: 1.17.5ubuntu5.3 and latest: 1.17.5ubuntu5"

I am not sure how I get to this. Is it due to my sources.list ?

After I re-installed, I have:

"installed version: 1.17.5ubuntu5 and latest: 1.17.5ubuntu5"

It is equivalent to a downgrade

  1. Best Answer

    Perform the following commands in a terminal, in order to update the package sources:

    sudo apt-get update

    Then run the installation of dkpg-dev again:

    sudo apt-get install dkpg-dev

    Based on your sources.list and an empty /etc/apt/sources.list.d, accepting the downgrade should pose no problem.

  2. You may allow it, that's not a problem. The packages synaptic offers are the dependencies of the packages you want to install.
