it shows extension updates

Can you show us the update server that gets this error? The client_id fallback in the XML is removed with 4.0 and the "client" [admininstator|site] should now be used without fallback

See: alikon/testcom#6

merged
i was confused by : https://docs.joomla.org/Deploying_an_Update_Server

Warning! Plugins and front-end modules are automatically installed with a client of 0 (site), but you will need to specify the client in an update or it will default to 1 (administrator) and then found update would not be shown because it would not match any extension.

yes alikon/testcom#6 fixed it, they need
<client>site</client> in the plugin manifest

The new client setting works for 3.x already too but we had a fallback thats gone since nearly one year in 4.0: #28767

I am experiencing this issue on both an upgrade to, and a fresh install of, J! 4.2.8. I get this error any time I install an extension.
Joomla!: 4.2.8
PostgreSQL: 14
Ubuntu: 22.04
