I have the chipset that doesn't support usb installation, so i was forced to use live dvd to install the CAElinux 2018. At the stage of programms copying the installer faced the error due to badly burned blocks of the dvd, but has succeed with completing the installation of the rest Ubuntu 16. So I have now only some programs, not the all possible, say, I see no Elmer and Cura. I know there is a way to mount the iso file as a virtual dvd and set it up as the repo. How can be the missed programs being installed then from inside the already working CAElinux installation? And how to define what iI m missing. Any hacks are welcomed.

I tried to mount caelinux image as mounted media and add its lcoation as the repo in apt.sources with lines like that:

deb file:/home/ilya/caelinux2018_iso/ xenial main
deb-src file:/home/ilya/caelinux2018_iso/ xenial main

however, on update attempt I'm getting

and, is the CAE software like Elmer there, in deb packages or not?

Hello,
sorry for the difficulties you encounter. Cura was not included in CAELinux 2018 because of lack of space left. However Slic3r is included.

Concerning Elmer, due to a last minute mistake, I forgot to include the start menu entry for Elmer. But you could try to open it directly from a CAE Terminal and run it from there: for example, try to run ElmerGUI and it should work.

Concerning CAELinux software packages: this release uses as many standard Deb packages as possible but many other software such as Salome & Aster for example have been manually installed in /opt (not from a deb package).

If for some reason you need to reinstall Elmer, run
sudo apt -get remove elmerfem-csc
and then install your chosen the latest Elmer from the developers:
sudo apt -get install elmerfem-csc

The package elmerfem-csc is from the CSC PPA and points to the latest release of Elmer. The other Elmer packages that you find in Ubuntu repositories (elmer, elmer-common) are outdated.

So it might well be that your installation is working normally in the end.

Cheers
