general update (no insider) came out on April 21st, where do I find the OSU1 more updated?

when will xbox release a offline update for xbox insider hub

Offline system updates using OSU1 cannot be used on consoles enrolled in a Insider preview.

OSU1 can only be used on console with the General Availability OS installed.

There will never be a OSU1 file released for Insider preview OS. The console has to be removed from the Insider program before using offline system updates.

If you describe the issue you're having, with any error codes you're seeing, we will endeavour to assist you.

The last system update that went out to everyone was on
April 21st, which leads me to believe you are part of the Insider program.

I'd recommend posting about this issue on the Xbox Insider section of Reddit. Official staff, moderators, and other Insiders are there to help.

Yes I was following the steps, but when I came to "Step 4: Download the Offline System Update file (OSU1)" and was to download the osu1 file, I found the link(www.xbox.com/.../osu1) just
didn't work. So where can I download the osu1 file?

I paste the same answer I made to a post you tacked on to.

There will never be a OSU1 file available to consoles enrolled in any Xbox Insider previews. The console has to be unenrolled from the preview before attempting an Offline System Update (OSU).

Normally, when the console is unenrolled the latest General Availability (GA) OS will be installed via the internet so a OSU is not required if your network connection is stable.

If you have unsuccessfully attempted to use a OSU1 file without unenrolling from Insiders, you need to factory reset the console.

The factory reset will install a base OS and if you have a stable network connection the console will download and install the latest OS available.

Reset console to factory defaults

"Last Alpha Skip Ahead Update was early March 2023"

This is not true. There have been several ASA Insider updates since March 2023. There was one yesterday 20th April 2023. I suggest you visit the Xbox Insiders Reddit site regularly and /or check the Insider app everyday if you want to stay in the ASA Insider preview.
