I am working on Linux Mint and when I tried installing IBM DB2 following the steps in below link, https://www.ibm.com/support/knowledgecenter/SSEPGG_11.5.0/com.ibm.db2.luw.qb.server.doc/doc/t0008875.html
I got this error in the step when I check installation requirements
DBT3505E The db2prereqcheck utility was unable to determine the Linux distribution level.
What to do?
Linux Mint is not a supported operating system for Db2.
If you dig hard enough, starting with this document, you can determine the supported operating systems:
https://www.ibm.com/support/pages/system-requirements-ibm-db2-linux-unix-and-windows
For Db2 v11.5, the supported Linux operating systems are RHEL7.5, SLES12SP3, or Ubuntu 16.04.
