Upadate is different from Upgrade.Update just check the sources,upgrade is the true update.You should try sudo apt update && sudo apt upgrade,or just type "sudo apt upgrade" directly.

Whatever, as much as it did, the result is always the same.

I need to confirm the updates most times, twice, as shown in the report above.

sudo apt update or sudo apt-get update is to know which updates will be performed and / or presented.

sudo apt upgrade -y or sudo apt-get upgrade -y is to confirm updates without the need for additional confirmation, sudo apt dist-upgrade -y or sudo apt-get dist-upgrade -y, ditto.

Could you upload some English screenshots plz?

Just use google translator, but I will do it for you.

There might be something wrong with the source of Brave,you could try to delete that source  or bear it if you really have to use Brave.

Hi

The source of the brave is from its official website, as follows: ( https://brave.com/linux/ )

This occurs regardless of whether it is a browser, brave, opera, chromium, vivaldi or the installation of any other application. It is often necessary to confirm twice for the .deb package to be installed. In a next update I will put a screen image (terminal). If you still want to.

Can't the user be free to choose their default browser? Brave is a browser excellence.

Ok,I'm waiting for your image,and I would get the Brave to test.

Hello @Ziggy

It follows what you asked for showing that it is necessary in the vast majority of times to confirm the update twice for it to occur.

The update report follows, showing two confirmations:

It should be the issue of this package,I will report

Thank You

Hello @Ziggy

Here's another example (!)
I believe that the issue is not summarized in just one specific package.
