I tried things (summary at the end of the post):
1)To know if the problem comes from my server:
Install a new empty 2-16-5 instance on the same server and upgrade to 3.
It didn’t works and gave me the same error, so there is an error about the server ( There’s no upgrade package available for download. This might indicate that the Mautic team is working on releasing a new version.).
2)I decided to create a local server on my computer, move my mautic onto, do the upgrade, and then reupload it on my web server.
Upgrade worked until the step 2 and then gave me these errors:

ERR_MOVE_MAUTIC_2_AND_3_FILES: Error while moving Mautic 2 or 3 files: One or more files couldn’t be moved to the Mautic 2 temp folder. This is really, really bad. Errors: app,media,plugins,themes,translations,vendor

So I did:
find . -type f -not -perm 644 -exec chmod 644 {} +
find . -type d -not -perm 644 -exec chmod 755 {} +
But still get same errors. Any ideas ?
3)Then, I tried to begin a new mautic 2.16.5 on my local server and do the upgrade, and it worked! So on the local server, my reel Mautic should work and the problem doesn’t come from the server but files themselves.
Summary:
On my web server: My Mautic upgrade doesn’t work " There’s no upgrade package available"
On my web server: new empty Mautic doesn’t work " There’s no upgrade package available"
On my computer local server: My Mautic " ERR_MOVE_MAUTIC_2_AND_3_FILES:"
On my computer local server: new empty Mautic WORKS
