Running Ubuntu 16.04 on a HP Pavilion laptop
In following your tutorial “How to set Up an OpenVPN server on Ububtu 16.04” I got to step 4 “Build the Certificate Authority” and when I ran the ./build-ca command I got the following output:

Generating a 2048 bit RSA private key
........................................................+++
……+++
unable to write ‘random state’

writing new private key to 'ca.key’

As you can see it is telling me it can not write the random state. I want to know if I can ignore this message and continue or what I might try to fix it.

Any and all help is appreciated.

  • sorry I tried to bold the line “unable to write ‘random state’” but it did it to the following line. I am new to this site.

  • While I wait for an answer I decided to try to continue.
    Upon running the ./build-key-server server I go the same message on the last line of the output:

    1 out of 1 certificate requests certified, commit? [y/n]y
    Write out database with 1 new entries
    Data Base Updated
    unable to write ‘random state’

    Any and all help is appreciated.

Hi @raygolost

It’s usually because your .rnd is not owned by the user. You can remove it:

sudo rm ~/.rnd
