incorrect exit code on failure (branch package-update)

[chakl]

What happened?

When using "xst package install registry", I mistakenly specified an invalid package name/version combination (there is no version 6.0.1 of "tuttle"). xst reported the failure, but returns exit code 0 which means "success". When using xst from Ansible, a failed package installation would be reported as "success".

$ /usr/local/bin/xst package install registry http://e-editiones.org/tuttle 6.0.1 --registry http://A_VALID_REGISTRY/exist/apps/public-repo/

$ echo $?
0

xst should return non-zero on failed package installation.
