Bug#851066: flashplugin-nonfree: Mismatch between detected and available versions (Download file not available at people.debian.org)

2018-06-22 Thread James Lu 
Hello,

I can confirm that this patch works and fixes not only this bug but some
others[1][2] affecting the download process too.

I'll look at making an NMU (currently staged in Salsa[3]), which will
also fix a couple of unrelated but trivial bugs[4][5]. The changes are
effectively at
https://salsa.debian.org/jlu-guest/flashplugin-nonfree/compare/f9cdfd78a...master

I put that patch in a package, seems to be working okay.

Package: flashplugin-nonfree
Version: 1:3.7
Followup-For: Bug #851066

Okay, attached is that patch I mentioned in my previous message.
This patch adds a new option to update-flashplugin-nonfree:


--using 
Specifies the name of a local tar file instead of attempting to
discover and download the latest version.  This file is presumed to be a tar
file downloaded by hand from Adobe.com, containing the flash plugin
appropriate for your machine arch.  No checks are performed to ensure the
tar file is authentic; you should download such plugins *only* from
Adobe.com.


Hmm.  Now that I think about it, I should update the docs, too.

Seems to work well for me.  Feedback welcome.

Schwab

2017-04-20 Thread Leo L. Schwab 
Package: flashplugin-nonfree
Version: 1:3.7
Followup-For: Bug #851066

Dear Maintainer,

This note is more for followers of this bug than the maintainer.

I decided to spend some non-trivial time to try and craft a patch
that would skip downloading and checking the little information blobs from
~bartm's account, thereby removing the dependency on updates from ~bartm.
After a little while, I concluded that this approach would be nearly
impossible to solve in the general case.

The fundamental problem is that Adobe can't be relied upon to
provide a consistent URL for downloading the Flash tarball.  ~bartm's
solution to this issue appears to have been to extract crucial metadata from
the most current Linux download on Adobe's site (presumably by hand), place
them in a small text file along with some SHA512 hashes, and then GPG-sign
the file.

As a consequence, the files pulled from ~bartm's account contain
crucial metadata that the update-flashplugin-nonfree script needs to locate
and download the plugin from Adobe's site.  Obviously, it is impossible to
parse Adobe's Web pages at runtime, as they rely heavily (and unnecesarily)
on dynamic HTML and JavaScript; and Adobe's download directories don't
enumerate -- you either give it exactly the right URL, or you get a 404.

The next thing I'm going to try is to add an option to unpack and
install an already-downloaded Flash tar file.  Not nearly as seamless, but
far better than people doing it by hand.

2017-01-11 Thread Peter Denison 
Package: flashplugin-nonfree
Version: 1:3.7
Severity: important

Dear Maintainer,
Now Adobe has once again started releasing updates to the Linux version 
of the flash plugin, the updater recognises the version number of the latest 
version, but it is not yet available at people.debian.org.
In addition, the documentation states that the player will be downloaded from 
www.adobe.com, where it is clearly going there for the version information, but 
to poeple.debian.org for the actual file.

   * What led up to the situation?

Running 'update-flashplugin-nonfree --install'

   * What was the outcome of this action?

# update-flashplugin-nonfree --install
ERROR: wget failed to download 
http://people.debian.org/~bartm/flashplugin-nonfree/D5C0FC14/fp.24.0.0.194.sha512.amd64.pgp.asc
More information might be available at:
  http://wiki.debian.org/FlashPlayer

   * What outcome did you expect instead?

A proper update of the flash installer
