Cannot download some files index. they are ignored or used older version (translate under from polish)

Today also saw it updates to new kernel and uninstall old kernel. Something changes. Remove old packages or something else with older to newer. Something virtual box also. Very weird.

What is "packagekitd" and how do I make the Software Updater stop waiting for it?

[HSG]

Maybe it is also better to translate the Polish words to English.

[Bourne]

I have translated in (...)

software & updates
Other Software tab
Select the etcher.io repository
Click remove on the bottom toolbar.

You may want to search the web for a Focal Repository Release for etcher.io

[Bourne]

I wondering i must go to file where are repositiories and remove that.

[Aravisian]

You would need to elevate to root then navigate to /etc/apt/sources.list.d/ and search in that directory for the etcher.io file.

[Bourne]

/etc/apt/sources.list this is corrrect.

[Aravisian]

@Bourne

/etc/apt/sources.list

This file should only contain your default sources, such as the Zorin Repositories.
Unless you edited that file to manually add the etcher.io repository... It wouldn't be placed there by the system.
Instead, it would have its own file placed in /etc/apt/sources.list.d/ directory.
For example, if you used sudo add-apt-repository command.

[Bourne]

This is empty.

[Aravisian]

Because you opened it as a Text Editor in your terminal.
Try:

ls /etc/apt/sources.list.d

[Bourne]

yes there exist balena-etcher.list and is empty. Then I must remove a file with this name.

[Aravisian]

Yes, you can do

rm /etc/apt/sources.list.d/balena-etcher.list

if you want to stay in terminal.

[Bourne]

Still exist.

[Aravisian]

sudo -i

nautilus

navigate to /etc/apt/sources.list.d/balena-etcher.list

Right click on balena-etcher.list and from the menu, choose "Send to Trash" or "delete"

[Bourne]

With root it deleted your command rm /etc/apt/sources.list.d/balena-etcher.list

[Aravisian]

sudo apt update

and check that all is clear

[Bourne]

Yes. That is clear now without problem. Now i know how remove broken repositories.
