Hi,

I am using Maple 13, 16 and 17 on 64 bit ubuntu 14.04LTS without 

any problems.

I tried to start the above Maple versions after upgrading to ubuntu 18.04LTS. Unfortunately, Maple does not start and transmits an incorrect hostid error message. The error message for Maple 16 is pasted below.

The command ifconfig -a produces an ethernet address 00:21:70:a6:a4:4b that is identical to the hostid given in the license.dat file.

I believe that the license manager flexnet is 32 bit. I used the synaptic 

manager to install lsb-base and ia32-libs (synaptic package manager refused to install lsb-core and transmitted some error messages). However, this did not help and I obtained the same hostid error message.

I do not know what is causing the hostid error message. Maybe some script file/s in the Maple installation can be modified such that Maple starts correctly?

Any assistance in getting Maple 13, 16, 17 to start on ubuntu 18.04LTS 

would be much appreciated.

Thank you very much for your support.
CF
