Thank you for these info
It must be due to a last minute update problem and it was not intended to come with ccx 2.5...
I will try to fix this ASAP.
In the meantime, you can install ccx 2.6 with
sudo apt-get install calculix-2.6.1-mt-caelinux
Sorry for that undetected issue.
Ps: as a consequence this also means that calculix wizard will fail until ccx 2.6.1 is installed.

Hi Joel, great work as always, thanks very much for your efforts.
I have a clean install of Xubuntu 12.04 LTS and ran CAELinuxify-Me.sh to install CAELinux. Everything is pretty much great and most of what I have sampled works fine. Apart from installing updates and installing geeqie and mathomatic I have done nothing else to the system
I have come across 2 issues to date:
1 apt-get update returns "GPG error: download.opensuse.org ./ Release: The following signatures were invalid: KEYEXPIRED 1396321314"
2 I cannot persuade Impact to run even from the command line in /opt/Impact. Running ./ImpactGUI_JOGL_OGL_linux_amd64.sh returns the following:
Exception in thread "main" java.lang.UnsupportedClassVersionError: gui/ImpactGUI : Unsupported major.minor version 51.0
at java.lang.ClassLoader.defineClass1(Native Method)

at java.lang.ClassLoader.loadClass(ClassLoader.java:268)
Could not find the main class: gui.ImpactGUI. Program will exit.
Any help getting Impact to run would be appreciated

Hello, good to ear that it worked well.
For impact, the issue is related to the default version of Java used:
You need to set openjdk7 as default java runtime.
Run
sudo update-alternatives --config java
And then choose java-7-openjdk as default
This should do the trick.
If not you can try to force the use of java-6 version...
For gpg key, the simplest is to try to identify which package source (in /etc/apt/sources*) if giving you this error. Then, either
- just comment the line " deb ... " and run sudo apt-get update
- or try to reinstall the gpg key for that source.
If you can tell which source fails, I could give you a command to fix it.
Cheers

Hello,
ok, I see now. It seems that Gerris repository has again changed its key (it happens too often in my opinion...).
To fix this, two options:
1) if you don't use Gerris flow solver, disable this source:
a) run gksudo medit /etc/apt/sources.list.d/gerris.list
and comment the line by inserting # at the begining, like this:
# deb http://...
b)then run sudo apt-get update to reload the list of packages
2) if you use Gerris, you must reinstall the GPG key of the repository:
follow the procedure described here gfs.sourceforge.net/wiki/index.php/Ubuntu/Debian_installation
(just install the key, i.e the first two lines of code)
