sudo ./xsetup

If libncurses.so.5 is missing:

sudo apt-get install libncurses5

Run ISE:

. /opt/Xilinx/14.7/ISE_DS/settings64.sh
ise

ISE license manager is not able to detect the NIC when it is named by the BIOS, which is done by default in newer Ubuntu version.

Check the name of you NIC:

ip link show

For the ISE license manager the NIC name must start with “eth”.

To solve this problem:
1) edit the Grub configuration file.

sudo vi /etc/default/grub

2) Change Parameter:

GRUB_CMDLINE_LINUX=""

to

GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

3) Apply change to grub.

sudo grub-mkconfig -o /boot/grub/grub.cfg

4) Reboot.
