Unable to get Questa-Intel FPGA starter edition license working in Ubuntu

[EkanshBhatnagar]

Hi, 

My problem:

ekansh@ekansh-Y540-15IRH-PG0:~/intelFPGA_lite/21.1/questa_fse/bin$ ./vsim
Unable to checkout a license. Make sure your license file environment variable (e.g., LM_LICENSE_FILE)
is set correctly and then run 'lmutil lmdiag' to diagnose the problem.
Unable to checkout a license. Vsim is closing.
** Error: Invalid license environment. Application closing.

What I have already done:

- Got my license in the mail.

- set my LM_LICENSE_FILE variable using

 export LM_LICENSE_FILE="<my-path-to-email-license-file>"  in .bashrc

- restarted my computer/ also tried to source .bashrc.

- tried lmgrd, got this

ekansh@ekansh-Y540-15IRH-PG0:~/intelFPGA_lite/21.1/questa_fse/linux_x86_64$ 16:52:20 (lmgrd) Can't make directory /usr/tmp/.flexlm, errno: 2(No such file or directory)

Good day

Welcome to INTEL forum. But before setting up your license, would you kindly help check whether your machine is supported or not (OS) by referring to link below:
