Get package information from the snapshot.debian.org ex. source versions,binary versions and most important first_seen
entry in order to install/downgrade that is no longer in the official {stable,testing,unstable} repositories by adding/appending
deb [check-valid-until=no] http://snapshot.debian.org/archive/debian/first_seen unstable main contrib non-free
to the /etc/apt/sources.list.d/snapshot.list file
$ debsnapshot-cli -h
usage: debsnapshot-cli [-h] [-lb] [-ls] [-lbins] [--first-seen]
[-arch ARCHITECTURE] [--time-out TIME_OUT] [-v] [-w]
[package_version] package_name
find package information in debian.snapshot.org
positional arguments:
package_version set the target version of the package you wish you
package_name write the package name you wish to find
optional arguments:
-h, --help show this help message and exit
-lb, --all-binary-versions
find binary package versions and corresponding source
names and versions
-ls, --all-source-versions
list all available source versions for this package
-lbins, --all-binpackages-for-package-version
list all binary packages associated with this source
package at that version
--first-seen get information e.x first_seen
-arch ARCHITECTURE, --architecture ARCHITECTURE
define system architecture
--time-out TIME_OUT set timeout
-v, --version print debsnapshot-cli version
-w, --write-to-file add url entry to /etc/apt/sources.list.d/snapshot.list
debsnapshot-cli can throw a lot of output, some packages have =>200 versions but you can pipe it with |less or |head -n. This is an example with the spacefm [1][2] file manager that has relatively a small number of version ###examples
$ debsnapshot-cli spacefm

#####--first-seen -arch amd64 version package
by using the --info argument and the architecture it will print the first_seen entry. You have to add an architecture
for the official Debian ports.if -arch parameter does not match, it will try to match 'all' as an architecture (if it exists)
$ debsnapshot-cli --first-seen -arch amd64 0.9.2-1 spacefm
archive_name name path first_seen hash size
-------------- ------------------------- -------------------- ---------------- ---------------------------------------- ------

URL
----------------------------------------------------------------------------
deb http://snapshot.debian.org/archive/debian/20131221T035435Z unstable main
if you add -w or --write-to-file to the previous command it will ask you to write to /etc/apt/sources.list.d/snapshot.list
$ debsnapshot-cli --first-seen -arch amd64 --write-to-file 0.9.2-1 spacefm

at a minimum,debsnapshot-cli will check if the folder /etc/apt/sources.list.d/ exists, if it does not, it quits.
if a file with name snapshots.list exist in this path,it will append it
if the file does not exist in sources.list.d/ folder, it will first create the file with the write the entry.
Update with normal apt-get update or with
apt-get -o Acquire::Check-Valid-Until=false update if the url does not contain [check-valid-until=no]
or you can update only the snapshot repo with
apt-get -o Dir::Etc::sourcelist="sources.list.d/snapshot.list" -o Dir::Etc::sourceparts="-" -o APT::Get::List-Cleanup="0" -o Acquire::Check-Valid-Until=false update
provided that the you have a snapshot.list file in /etc/apt/sources.list.d/
