[Gambas-user] Repeat: Severe problem with update...

[ISS Boss]

   Outstanding!   I  can  understand  that,  Willy.   Thanks  for all the
   information.   I  printed out your email and stuck it in my loose-leaf
   notebook of "things to try if something blows up in Linux".
   I did notice the change in PPA, so it is very possible I did get the initial
   install from a PPA who later changed their key and messed me up.
   Thanks for the detailed explanation.  I need stuff like that if I'm going to
   learn  anything.   I've  been in computers/electronics since 1963, but
   relatively new to Linux.

New information on my problem.  I went to the GambasWIKI site and 
followed these three instructions under the "Gambas3 Stable" header 
(which is how I installed it the first time):

sudo add-apt-repository ppa:nemh/gambas3

sudo apt-get update

sudo apt-get install gambas3

What I have now when I open Gambas is and get system info is:


[System]
Gambas=3.5.3
OperatingSystem=Linux
Kernel=3.5.0-48-generic
Architecture=x86
Distribution=Ubuntu 12.04.4 LTS
Desktop=GNOME
Theme=QGtk
Language=en_US.UTF-8
Memory=2017M
[Libraries]
Cairo=libcairo.so.2.11000.2
Curl=libcurl.so.4.2.0
DBus=libdbus-1.so.3.5.8
GStreamer=libgstreamer-0.10.so.0.30.0
GStreamer=libgstreamer-1.0.so.0.1.0
GTK+=libgtk-x11-2.0.so.0.2400.10
OpenGL=libGL.so.1.2.0
Poppler=libpoppler.so.19.0.0
Qt4=libQtCore.so.4.8.1
SDL=libSDL-1.2.so.0.11.3

NOTE that Gambas 3.5.2 has been replaced by Gambas 3.5.3 (the only change).

When I issued the first install instruction, I get results I was not 
anticipating.  They were as follows:

bill at ...3318...:~$ sudo add-apt-repository ppa:nemh/gambas3
[sudo] password for bill:

This indicates that something is wrong with an installation script
somewhere doesn't it?  Shouldn't that be fixed?

When I executed the "Install" command, I asked me if I wanted to install
"unverified" packages.  I answered "Y". and it installed.

Now, when I run the Update Manager it says I have no updates to
install.  So, I guess my "problem" is solved for the time being. Will
this happen the next time updates are up for Gambas?

You should be good now if:
1. The proper PPA is added to your sources.list.
2. The Public Key of all PPA's used are on your system

These PPA's are the software repositories that are checked when
running:

$ sudo apt-get update

And these are the repositories updates will be installed from when
running:

$ sudo apt-get upgrade

Next time when PPA memh/gambas3 gets an updated gambas version the
apt-get update and upgrade will upgrade your version.

The message:

-----
"Requires installation of untrusted packages."

"This action would require the installation of packages from not
authenticated sources"
------

could have originated from another PPA as your output in previous mail
said:

------
W: GPG error: [97][2]http://ppa.launchpad.net precise Release: The
following
   signatures couldn't be verified because the public key is not
available:
   NO_PUBKEY 14E4942973C62A1B
-------

This means that packages from this PPA are not trusted because of public
key missing for this PPA.

for more info on how to install a Public Key from a PPA.
