I'd like to see and compare versions of all packages in two different repos.
Something like:

libfoo | 1.2 | 1.3
libbar | 2.4 | 3.0
libbaz | ... | ...

Is there some such web?

Or a way to obtain list of all package versions in a repo, so I could compare myself by a script?

The use case is to be able to know what versions will change after system upgrade.

Use the tool rmadison for one package version information in different distributions
(well then different repositories)

1. sudo apt-get install devscripts


2. rmadison [the package name]

For example,

$ rmadison alsa-utils

and the output looks like [package version distro arch]:

 alsa-utils | 1.0.25-1ubuntu5   | precise         | source, amd64, armel, armhf, i386, powerpc

 alsa-utils | 1.0.25-1ubuntu5.2 | precise-updates | source, amd64, armel, armhf, i386, powerpc

 alsa-utils | 1.0.27.2-1ubuntu2 | trusty          | source, amd64, arm64, armhf, i386, powerpc, ppc64el

 alsa-utils | 1.0.28-1ubuntu2   | vivid           | source, amd64, arm64, armhf, i386, powerpc, ppc64el

 alsa-utils | 1.0.29-0ubuntu1   | wily            | source, amd64, arm64, armhf, i386, powerpc, ppc64el

Or you could go to this website to see the lists

http://packages.ubuntu.com/

You can visit Ubuntuupdates as follows:

Search according to packages:

Then click Package Search (you will find differnt versions in page such as shown below):

You can also find possible matches of package name according to version and then click anyone to know more details!

Here package names are only used as example. Hope this helps to find appropriate package-name + PPA according to Ubuntu-release.

For two different repositories, you can compare the Packages files. This file is specific to the release channel (trusty, trusty-updates, etc.), the component (main, multiverse, etc.) and the type of the packages (binary-amd64, source, etc.).

Typically you can locate the file at:

/ubuntu/dists/$CHANNEL/$COMPONENT/binary-$ARCH/Packages{,.gz,.bz2,.xz}

relative to the root of most official mirrors.

An example would be http://mirror.cse.iitk.ac.in/ubuntu/dists/precise/main/binary-amd64/Packages.gz

You can fetch the Packages files you're interested in (uncompress if necessary), grep for Package and Version, then diff the output.

A sample code:

curl -s http://mirror.cse.iitk.ac.in/ubuntu/dists/trusty/main/binary-amd64/Packages.gz | gunzip | grep -E '^(Package|Version)' | awk 'ORS=NR%2?FS:RS {print $2}' > repo-a.txt 

curl -s ftp://ftp.iitb.ac.in/distributions/ubuntu/archives/dists/trusty/main/binary-amd64/Packages.gz | gunzip | grep -E '^(Package|Version)' | awk 'ORS=NR%2?FS:RS {print $2}' > repo-b.txt 

diff repo-a.txt repo-b.txt
