fix: error handle in initial configuration

[myungjin]

Description

When post installation script is triggered during installation, the initialization check file (init.txt) is not present, which raises an exception. This leads to the failed installation. The issue is fixed by catching the error and suppressing it (which is okay because it is only happening during the installation).
