Context:
Our app has a network system extension. After updating it via MDM sometimes the app and the extension have different versions until you restart the app. I suspect that it is because the app is not quit before installing.
As a fix I am trying to create a .pkg with preinstall and postinstall script, that would close the app before installation and open it after installation.
My code:
FileUtils.mkdir_p("install_scripts")
File.open('install_scripts/preinstall', 'w') do |file|
file.puts "#!/bin/bash\nosascript -e 'quit app \"#{options[:app_name]}\"'\nexit 0"
end
File.open('install_scripts/postinstall', 'w') do |file|
file.puts "#!/bin/bash\nopen -a '#{options[:app_name]}'\nexit 0'"
end
sh "chmod a+x install_scripts/preinstall"
sh "chmod a+x install_scripts/postinstall"
sh(
"pkgbuild",
"--scripts", "install_scripts",
"--identifier", ***_identifier(options),
"--component", "../#{options[:build_path]}/#{options[:app_name]}.app",
"--install-location", "/Applications/#{options[:app_name]}.app",
"Distribution.pkg"
)
sh(
"productbuild",
"--synthesize",
"--package", "Distribution.pkg",
"Distribution.xml"
)
sh(
"productbuild",
"--distribution", "Distribution.xml",
"--sign", "Developer ID Installer: *** Inc. (#{ENV["APPLE_TEAM_ID"]})",
"--package-path", ".",
"../artifacts/#{options[:app_name]}.pkg"
)
Issue:
I haven't got it to actually install the app or to close or open the running app. I've tried several changes. The code above fails with this error. Do you see an issue in my code, or could you point me to alternative implementation?
