Well, today both Xcode and altool are working again. No changes on my side.

Thank you. I’ll give notarytool a try. Any suggestions on how to resolve the Xcode issue? I have no pending agreements, all agreements are signed and there’s only one team.

I just started getting the same error in Xcode and I'm NOT a member of multiple teams. I also don't have any outstanding agreements to be signed. If it helps, altool is giving me this error when trying to notarize a .pkg (the same workflow was working two days ago): java.io.IOException: Server returned HTTP response code: 504 for URL: https://contentdelivery.itunes.apple.com/transporter/lib/osgibootstrapper.jar at java.base/sun.net.www.protocol.http.HttpURLConnection.getInputStream0(Unknown Source) at java.base/sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.base/sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(Unknown Source) at java.base/java.net.URL.openStream(Unknown Source) at com.apple.transporter.launcher.Application.start(Application.java:340) at com.apple.transporter.launcher.Application.main(Application.java:947) java.lang.reflect.InvocationTargetException at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.base/java.lang.reflect.Method.invoke(Unknown Source) at com.apple.transporter.launcher.Application.start(Application.java:450) at com.apple.transporter.launcher.Application.main(Application.java:947) Caused by: org.osgi.framework.BundleException: Could not resolve module: com.apple.transporter.starter [17]   Unresolved requirement: Import-Package: javax.annotation; version="[3.0.0,4.0.0)"; resolution:="optional"   Unresolved requirement: Import-Package: com.apple.transporter.launcher.asu; version="[1.0.0,2.0.0)" at org.eclipse.osgi.container.Module.start(Module.java:463) at org.eclipse.osgi.internal.framework.EquinoxBundle.start(EquinoxBundle.java:440) at org.eclipse.osgi.internal.framework.EquinoxBundle.start(EquinoxBundle.java:459) at com.apple.transporter.bootstrap.BootstrapperPhase2.bootstrapBundles(BootstrapperPhase2.java:321) at com.apple.transporter.bootstrap.BootstrapperPhase2.start(BootstrapperPhase2.java:153) at com.apple.transporter.bootstrap.BootstrapperPhase1.startOSGiFramework(BootstrapperPhase1.java:319) at com.apple.transporter.bootstrap.BootstrapperPhase1.bootstrap(BootstrapperPhase1.java:99) at com.apple.transporter.bootstrap.BootstrapperPhase1.bootstrap(BootstrapperPhase1.java:59) at com.apple.transporter.launcher.Launcher.launchBootstrapper(Launcher.java:37) ... 6 more  Out: *** Error: Notarization failed for '<EDITED>.pkg'. *** Error: An error occurred uploading to Apple Services.

Same here. Notarizing using altool. It first complained it couldn't find metadata.xml. Now it's complaining it's not finding the .dmg, which is the file I'm trying to notarize. Same script has worked for months with no problems. Retrying is not helping. I'm running altool on Big Sur 11.2.3 (Intel and M1, same results). Any ideas?

Thank you, Quinn. That was exactly what needed to be done. Adrian
