Information about client software
Installation was initiated by SQLPlus 19

SQL*Plus: Release 19.0.0.0.0 - Production on Thu Mar 11 07:57:59 2021
Version 19.9.0.0.0

To Reproduce
Steps to reproduce the behavior:

1. Go to OCI
2. Create an AlwaysFree ATP Instance and choose 21c as your Database Version
3. Connect as Admin and install utPLSQL (I did it headless)
4. See error

Expected behavior
utPLSQL runs through it's installation process without error ;-)

Example code
/

Additional context
The reason why installation is failing is caused by the fact that oracle has deprecated Package DBMS_OBFUSCATION_TOOLKIT
see: https://docs.oracle.com/en/database/oracle/oracle-database/21/upgrd/behavior-changes-deprecated-desupport-oracle-database.html#GUID-92A36569-B4B6-49AB-857E-6963D93D6A0D

[PhilippSalvisberg]

utPLSQL version 3.1.10 cannot be installed in an Oracle Database 21c.

However, you can install the current develop version in 21c. See also #1111 .

[MaikMichel]

Ok, thank you for your fast response ;-)

[PhilippSalvisberg]

You're welcome. I close this issue.

Feel free to reopen it if you encounter problems installing the current develop version.
