Quartus 10.1 linux.

The megawizard issue may simply be related to the fact that you were unable to Install device files. So, you should try to manually install the QDA device packages.

To do this,

1.- Go to the directory where the installer source files are. From the log file you attached, it seems to be:

/mnt/sda3/temp/10.1_quartus_free_linux/altera_installer/bin/../../devices/subscription/

2.- For every QDA file that you see in the folder (except from arriagx.qda that seem to have worked), do

quartus_sh --qinstall -qda <qda file>

Example

quartus_sh --qinstall -qda arriaii.qda

Then see if that fixes the problem.
