Update your Launchpad PPA repositories and apt keys

[forger]

Your Launchpad PPA: three important changes -------------------------------------------- We have three important items of news regarding your Launchpad Personal Package Archive(s): * your PPA now has its own key and packages are now signed * your PPA URLs and upload paths are going to change * we are going to start removing deleted/superseded packages from our servers. These changes affect PPAs owned both by individuals and teams.

I made a perl script that:
- Can detect and fix any launchpad PPA link from apt .list files
- Backs up the original source list (e.g. /etc/apt/sources.list as
/etc/apt/sources.list.backup)
- Imports GPG keys for the links detected apt .list files

Requirements:
- Administrative privileges
- Perl
- Internet connection
- HTML::Parser IO::Socket::SSL

sudo apt-get install libhtml-parser-perl libio-socket-ssl-perl

How to use it:

wget http://savvas.radevic.com/launchpad/launchpad-ppa-fix.tar.gz -O launchpad-ppa-fix.tar.gz
tar xzvf launchpad-ppa-fix.tar.gz
perl launchpad-ppa-fix.pl
sudo apt-get update
rm launchpad-ppa-fix.tar.gz launchpad-ppa-fix.pl

Fallback plan:
If anything goes wrong, I guess the only important thing changed are the .list files.
The script creates a backup for each .list file, for example /etc/apt/sources.list.d/test.list
is backed up as /etc/apt/sources.list.d/test.list.backup

You can see the output and restore whichever file required.

Code
bazaar: bzr branch lp:~medigeek/+junk/launchpad-ppa-fix

I've moved this to General Help from Tutorials & Tips. My reasoning is that this is really just a script that does everything for you. Scripts updating repositories especially are generally discouraged, because if it fails then the user is left with an unusable system save for the backup list.

You are free to resubmit your tutorial, but please make sure that it details how a user can update their sources and add GPG keys, don't just do it for them with a script.

Ah ok

That is already explained here:

Thanks for the comment!
I've added support for http_proxy environment fields, should be able to handle requests behind proxy servers.
