Problem with update manager - is that normal?

[fervent knoll]

Today I've got this error in update manager (in picture). I've installed google chrome using terminal and I don't know this is a reason. What should I do? I know this picture is not in English, so please translate it with Lens

Go to the terminal and type

sudo apt update

screenshot the result

A screenshot from terminal?

Yes

Also, how exactly did you installed chrome?

[fervent knoll]

The problem repaired itself, I ran this command and this is what I got

I followed this instruction https://www.digitalocean.com/community/tutorials/install-chrome-on-linux-mint

Most of the errors are that some software sources is duplicated in multiple files, and that spotify source doesn't have a valid key anymore.

Can you screenshot your "software sources" window?

And for chrome, it's much easier to go to google chrome site and download deb package there

I tried but I couldn't install

[fervent knoll]

Software sources?

yes

if you want, we can try that again after solving this

[fervent knoll]

How?

[static totem]

Just open your menu and start typing, it should find it

I don't know how it says in Polish, is it software manager or update manager?

[static totem]

If the translator is correct, it should be "źródła oprogramowania"

[fervent knoll]

I found this

[static totem]

Yes, screenshot every tab on the left side please

[fervent knoll]

Ok

[static totem]

On the 3rd tab you have 2 google entries, delete the first one. and on the 5th tab, press the 3rd button, it should say remove duplicates or something to that effect

[fervent knoll]

Done

[static totem]

close the window and run

sudo apt update

again, screenshot the results

[static totem]

seems ok. your update manager should work now

Thanks a lot
