Using apt upgrade and apt dist-upgrade is quite confusing since the output usually looks something like this. Is there an option or possibility to make the output better readable?

From that I have to decide if it is safe to upgrade or not. The packagelist is just plain ugly and confusing. I would like to have a better overview about what will be upgraded.

For example, yum (from CentOS) gives a much cleaner view when upgrading. One can easily see which packages will be upgraded, to which version (e.g., if it is a small or major version jump) and also how big the pacakge is to download.

$ sudo yum update

Is this ok [y/N]:
  • You have multiple options. 1.) Patch it yourself 2.) Ask upstream if they'll fix it 3.) Switch to CentOS if you really like yum that much. Finally I am curious as to what you don't find readable about the output (aside from it being just a wall of text :p) – j-money Feb 8 at 10:44

    Another option, use a narrower terminal window. Humans are not too good at reading more than 70 chars per line. – gboffi Feb 8 at 14:06
  • @j-money it's exactly the "wall of text", as you call it, which I dislike. Lucky for me, some have suggested out-of-the-box solutions. – masgo Feb 8 at 18:34

You can get this better output by asking for more verbose version output (-V, --verbose-versions, see man apt-get):

    This is a great solution. yum is still slightly cleaner in it's output, but this is 95% of it. I can live with that. Since this question attracted so may, I will leave it open for another day or two until accepting your answer. – masgo Feb 8 at 18:36

I see two solutions:

  1. use simulation in apt/apt-get:

  2. use interactive form of Aptitude instead of plain apt/apt-get

    Aptitude

    Note: I have collapsed the Packages to be upgraded section for readability of other sections.

  • Thank you for the suggestions. Aptitude is nice, but I had some problems with it in the past when things got messy (short story: the dependencies where in fact impossible to fulfill. aptitude though it could fulfill them and did the upgrade; which broke the system). But it's still nice to have multiple options on the table. – masgo Feb 8 at 18:44
  • If you're going to do a dry run first (simulate), then you can pipe the output into awk or sed, etc. configured to make the output look any way you like. – Joe Feb 14 at 18:50
