Hello again.
It's a while yet, even before updating to 1.27, since my installation fails to update (core and modules) via the interface (manual updates run smoothly).
After downloading an available update, I get this error (site has been automatically put into maintance mode, and there are no further entries in the error log):
An AJAX HTTP error occurred.
HTTP Result Code: 500 Debugging information follows.
Path: https://.../core/authorize.php?batch=1&id=70&op=do_nojs&op=do
StatusText: Service unavailable (with message)
ResponseText: Error: Class "ModuleUpdater" not found in installer_authorize_batch_copy_project() (line 151 of /var/www/vhosts/.../core/modules/installer/installer.authorize.inc).

Update failed! See the log below for more information. Your site is still in maintenance mode.
I've never touched installer.authorize.inc ... and I'm lost where to start debugging.
It's not crucial for my site, but kind of anoying... If someone has an idea how to solve, please let me know.
Thank you and best regards
You could try to run the site on your personal computer and see if the error still occurs.
You could run it in Lando, ddev, Xampp, Wampp or such.
