INS-20802: Oracle Net Configuration Assistant failed error on Oracle Linux (6.10)

При установке Oracle database 11g, на 11 шаге возникла ошибка:

INS-20802: Oracle Net Configuration Assistant failed
Cause - The plug-in failed in its perform method
Action - Refer to the logs or contact Oracle Support Services. Log File Location
/mnt/u01/app/oraInventory/logs/installActions2021-03-13_05-08-32PM.log

Аналогичная ошибка и была при установке СУБД Oracle на Windows тут. Но судя по ошибке в логе, проблема здесь возникла не из-за переменной среды.

По совету в записи пошел проверять логи трассировки:

При этом, IP машины на котором запущена инсталляция совершенно другая (172.*.*.*).

Решение:

В файле etc/hosts добавить/изменить на корректное название и IP адрес сервера.

В моем случае было так:

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

Поэтому пришлось добавить строку с IP адресом сервера:

172.*.*.* dbserver38

Итог etc/hosts выглядит так:

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

172.*.*.* dbserver38

А установка после нажатия "Retry" выглядит так:
