I have been trying to install everything needed for Teamwork Cloud 2021X using these instructions https://docs.nomagic.com/display/TWCloud2021x/Installation+on+Linux+using+scripts
When I get to executing install_twc2021xRefresh1_centos7.sh I get the following output

Creating temporary directory for install anywhereIMPORTANT:When prompted for user to run service, use twcloudWhen prompted for Java Home location, use Java 11 location, e.g., /opt/local/java/jdk-11.0.9.1+1-Press any key to continue ...: Binary file /data/install/custom matchesBinary file /data/install/custom matchesBinary file /data/install/custom matchesgzip: /data/install/_tmp/install.dir.43574/Linux/resource/vm.tar.Z: not in gzip format./twcloud_2021x_installer_linux64.bin: line 775: uncompress: command not foundgzip: /data/install/_tmp/install.dir.43574/Linux/resource/vm.tar.Z: not in gzip formatBinary file /data/install/custom matches Binary file /data/install/custom matcheschown: cannot access '/opt/local/TeamworkCloud/': No such file or directorysed: can't read /opt/local/TeamworkCloud/configuration/application.conf: No such file or directorysed: can't read /opt/local/TeamworkCloud/AuthServer/config/authserver.properties: No such file or directory```

Here is the “custom” file that is created after failure:

It seems as though these error messages are all being generated by default regardless of changes I make

This occurs even though I have enough space and full permissions for $INSTBASE – /opt/local and $IATEMPDIR – /tmp) Although, the instructions do not refer to needing to set these; I tried it to troubleshoot and get the same errors.

*I did have to modify twcloud_2021x_installer_linux64.bin to allow Rocky as the OS (It checks for Cent-OS, which Rocky is meant to be binary compatible with)

Added a check for the presence of /etc/rocky-release file alongside the existing check for /etc/centos-release. If either file exists, it assigns the contents to DISTRO_NAME.
