Error installing 12c on Linux 7 >>> Could not execute auto check for display colors using command /

M.KamranJan 20 2020 — edited Jan 22 2020

Hi

We have 2 machines running Red Hat Enterprise Linux Server release 7.7 (Maipo)

We are trying to install 12cR2

We installed the following packages

yum install xorg-x11-server-Xorg xorg-x11-xauth xorg-x11-apps -y

yum install xhost

Oracle user is created as below

~/staging/database$ id oracle

uid=1000(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba),16777216(domain users),16777217(e1_users),16777218(sales_branches-rw)

We are able to pull up xclock with no issues

~/staging/database$ xhost +

access control disabled, clients can connect from any host

:~/staging/database$ xclock

Warning: Missing charsets in String to FontSet conversion

But every time we try to run the installer. we keep getting the following..

oracle@tpcq2atgdb01:~/staging/database$ ./runInstaller

Starting Oracle Universal Installer...

We tried setting the DISPLAY as below.. yet still the same error

oracle:~/staging/database$ who

oracle pts/1 2020-01-20 14:50 (10.202.41.13)

oracle:~/staging/database$ echo $TERM

xterm

oracle:~/staging/database$ export DISPLAY=10.202.41.13.0.0

oracle:~/staging/database$ echo $DISPLAY

10.202.41.13.0.0

Can someone please help us as to how to fix this?

We are using MobaXterm and we tried putty as well as the SSH client but getting same error

Thanks
