VERSION=“18.04.2 LTS (Bionic Beaver)”

**Steps to reproduce:**  
Very start of the installation:  
as root: /usr/share/one/install\_gems

**Current results:**  
I can only assume that since the above will not compile it maybe causing the following error:  
/var/log/one/oned.log  
…  
Sat Jun 15 22:14:49 2019 [Z0][MAD][E]: MAD did not answer INIT command  
Sat Jun 15 22:14:49 2019 [Z0][ONE][E]: Could not load driver  
…

**Expected results:**  
I expected NOT to have the following error:
