orapwd gives OPW-00029 Password complexity failed in #Oracle 12.2

When I tried to create a password file for a 12.2 database, it initially failed with my favorite (simple) password:

[oracle@uhesse dbs]$ orapwd file=$ORACLE_HOME/dbs/orapwprima password=oracle

OPW-00029: Password complexity failed for SYS user : Password must contain at least 8 characters.

Two options to resolve this: Either provide a password that passes the complexity check, like:

[oracle@uhesse dbs]$ orapwd file=$ORACLE_HOME/dbs/orapwprima password=Very_Complex§1

Windows

orapwd file=C:\oracle\Administrator\product\12.2.0\dbhome_1\database\PWDIFS10CDB.ora format=12 password=Manager_1

Or create the password file in 12.1 format (default being 12.2 format)

[oracle@uhesse dbs]$ orapwd describe file=orapwprima
Password file Description : format=12.2 
[oracle@uhesse dbs]$ rm orapwprima
[oracle@uhesse dbs]$ orapwd file=$ORACLE_HOME/dbs/orapwprima password=oracle format=12
[oracle@uhesse dbs]$ orapwd describe file=orapwprima
Password file Description : format=12
