Set SKIP_VALIDATIONS in /etc/sysconfig/oracle-xe-18c.conf to false, and retry.

XE rpm install was thus successful, but the configuration step (i.e. database create) not?

With XE installed, sqlplus is available - which means you can create a pfile, and do an instance startup, to determine just what the memory issue is.

Or if this works, look at dbca and the Java runtime used by it.

Changed configuration should look like this:

$SU -s /bin/bash $ORACLE_OWNER -c "(echo '$ORACLE_PASSWORD'; echo '$ORACLE_PASSWORD'; echo '$ORACLE_PASSWORD') | $DBCA -silent -createDatabase -gdbName $ORACLE_SID -templateName $TEMPLATE_NAME -characterSet $CHARSET -createAsContainerDatabase $CREATE_AS_CDB -numberOfPDBs $NUMBER_OF_PDBS -pdbName $PDB_NAME -sid $ORACLE_SID -emConfiguration DBEXPRESS -emExpressPort $EM_EXPRESS_PORT -J-Doracle.assistants.dbca.validate.DBCredentials=false -J-Doracle.assistants.dbca.validate.ConfigurationParams=false -sampleSchema true $SQLSCRIPT_CONSTRUCT $DBFILE_CONSTRUCT $MEMORY_CONSTRUCT"

It works fine on Debian 9.8 after installing required packages, converting rpm to deb and with changes in configuration file
