I have installed a universal-forwarder on a Ubuntu Linux box without error, here is some validation:
Splunk list forward-server
The forward does show up in monitor, but when I get to add the Forwarder under Settings -> Data. It doesn't show any forwarders available and show the refresh button. I did also download and copy Splunk for Linux under /opt/splunkforwarder/etc/apps/Splunk_TA_linux as first goal is to get performance data into the cloud.
Did you enable to configuration ? Read through the "Enable the data and scripted inputs with configuration files" section in the below link.
Note on the install, you also need it on the Search Head and Indexers. You may need to raise a Splunk Support ticket for this
Thank You for your reply!
There is no $SPLUNK_HOME/etc/apps/Splunk_TA_nix/local directory there is a $SPLUNK_HOME/etc/apps/Splunk_TA_linux /default directory. There also is no existing input.conf file, the files available in $SPLUNK_HOME/etc/apps/Splunk_TA_linux /default are:
/opt/splunkforwarder/etc/apps/Splunk_TA_linux/default$ ls -ltr
-rw-r--r-- 1 splunk splunk 2833 Apr 19 2018 transforms.conf

drwxr-xr-x 3 splunk splunk 16 Apr 19 2018 data

This is Splunk_TA_linux which in my understanding is different then Splunk Add-on for Unix and Linux, I used Splunk_TA_linux because it didn't require logging a support ticket.
