        If you have upgraded your system since your initial install (which is the case for most people I think), is better to use the manifest file of your current Ubuntu release version.Diego V– Diego V2015-02-13 11:20:59 +00:00Commented Feb 13, 2015 at 11:20

        If you've upgraded, I think you would need to use both files, not just the manifest file. You can easily do that by just adding another comparison. The manifest file unfortunately does not contain everything that the initial_status.gz file does (I checked).jmiserez– jmiserez2015-02-24 13:00:15 +00:00Commented Feb 24, 2015 at 13:00

        I'm impressed! I found a missing piece however. What about packages that were initially installed but then explicitly manually removed, however, later explicitly manually reinstalled? I found this in a working system.n611x007– n611x0072015-08-25 09:22:49 +00:00Commented Aug 25, 2015 at 9:22

        1I've made a question unix.SE/225330: List explicitly removed packages (apt) to address the bulk of the job.n611x007– n611x0072015-08-25 10:33:47 +00:00Commented Aug 25, 2015 at 10:33

        1This is better than the accepted solution, since the mirror.pnl.gov/releases/precise/… URL in the accepted solution is now a 404.rmunn– rmunn2016-01-11 02:07:20 +00:00Commented Jan 11, 2016 at 2:07

        How to Format

                create code fences with backticks ` or tildes ~
                ```
 like so
 ```
- 
                add language identifier to highlight code
                ```python
 def function(foo):
 print(foo)
 ```
- put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes `like _so_`
- quote by placing > at start of line
- to make links (use https whenever possible)
                <https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
            How to Tag
        
        A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
