Some advanced methods of oracle Xe are not supported, and the installer needs to consider clearly
The installation environment is the Ubuntu16.04 version, and the official oracle Xe is Linux 64 and the Rpm package. Rpm packages cannot be installed directly and need to be converted using Alien. Alien installation command
sudo apt-get install alien
Note adding the parameter -c, otherwise there will be a warning. Note that the RPM package needs to be copied to the EXT4 hard disk, and the conversion will fail under NTFS.
dhlsoft@djpc:~/tool$ sudo alien oracle-xe-11.2.0-1.0.x86_64.rpm
Warning: Skipping conversion of scripts in package oracle-xe: postinst postrm preinst prerm
Warning: Use the --scripts parameter to include the scripts.
dhlsoft@djpc:~/tool$ sudo alien -c oracle-xe-11.2.0-1.0.x86_64.rpm
The conversion process is very slow and takes about ten minutes, and there is no prompt message during that time. You need to wait patiently for the conversion to complete. Under the path of the rpm package, a .deb package with the same name will be generated. The next step is to install
dhlsoft@djpc:~/tool$ sudo chmod 777 oracle-xe_11.2.0-2_amd64.deb
dhlsoft@djpc:~/tool$ sudo dpkg -i oracle-xe_11.2.0-2_amd64.deb

The installation will be completed soon, during which you will be prompted that you need to use the root user for configuration. An error will be reported when this command is run, /sbin/chkconfig does not exist. Check the /var/lib/dpkg/info/oracle-xe.postinst script and find the following paragraph in the script:
if [ -f /etc/SuSE-release ]
then cp -f /u01/app/oracle/product/11.2.0/xe/config/scripts/oracle-xe.sles /etc/init.d/oracle-xe /usr/lib/lsb/install_initd /etc/init.d/oracle-xe > /dev/null 2>&1
/sbin/insserv /etc/init.d/oracle-xe > /dev/null 2>&1
/sbin/SuSEconfig > /dev/null 2>&1
#else
#/sbin/chkconfig --add oracle-xe
fi
Comment out line 113 of the bolded part above, and then execute
