Hello!
I wanted to know what does the following mean and if I can fix these issues:
W: http://deb.playonlinux.com/dists/trusty/InRelease: Signature by key 74F7358425EEB6176094C884E0F72778C4676186 uses weak digest algorithm (SHA1) W: http://liveusb.info/multisystem/depot/dists/all/Release.gpg: Signature by key 32027DE3D67157C45E69C0AE4E940D7FDD7FB8CC uses weak digest algorithm (SHA1) W: The repository 'http://ppa.launchpad.net/ubuntu-audio-dev/ppa/ubuntu xenial Release' does not have a Release file. N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use. N: See apt-secure(8) manpage for repository creation and user configuration details. E: Failed to fetch http://ppa.launchpad.net/ubuntu-audio-dev/ppa/ubuntu/dists/xenial/main/binary-amd64/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead.
Every time I hit sudo apt-get update in terminal I get these errors. If theyâre safe then itâs fine by me, but maybe thereâs anything I need to do or check.
Thanks in advance!

Hi
Please try and run the âFixesâ from the software boutique, last icon on the right.

Everything else except âUpdate sources listâ works. This one gives a similar error:
W:http://deb.playonlinux.com/dists/trusty/InRelease: Signature by key 74F7358425EEB6176094C884E0F72778C4676186 uses weak digest algorithm (SHA1), W:The repository 'http://ppa.launchpad.net/ubuntu-audio-dev/ppa/ubuntu xenial Release' does not have a Release file., W:Data from such a repository can't be authenticated and is therefore potentially dangerous to use., W:See apt-secure(8) manpage for repository creation and user configuration details., W:http://liveusb.info/multisystem/depot/dists/all/Release.gpg: Signature by key 32027DE3D67157C45E69C0AE4E940D7FDD7FB8CC uses weak digest algorithm (SHA1), E:Failed to fetch http://ppa.launchpad.net/ubuntu-audio-dev/ppa/ubuntu/dists/xenial/main/binary-amd64/Packages 404 Not Found, E:Some index files failed to download.

Have you subscribed to welcome updates? (Welcome splash screen, top right corner)
I think I have, atleast I remember pressing it and the option is not there at the moment.
OK, I think youâve installed some PPAs that are not provided through the boutique.
You can see all the boutiqueâs ppas here: https://paste.ubuntu.com/23181937/
See here how to remove old ppas: https://askubuntu.com/questions/307/how-can-ppas-be-removed
I donât want to make a new topic, but instead Iâll post my problem here. Itâs again related to repositories and now whenever I want to do âsoftware updaterâ it gives an error: âFailed to connect to internetâ despite the fact that I have internet connection. Iâve tried to change servers, but nothing helps.
When I execute sudo apt-get update I get the following errors:
N: Ignoring file '20auto-upgrades.ucf-dist' in directory '/etc/apt/apt.conf.d/' as it has an invalid filename extension W: The repository 'http://ppa.launchpad.net/skunk/pepper-flash/ubuntu xenial Release' does not have a Release file. N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use. N: See apt-secure(8) manpage for repository creation and user configuration details. E: Failed to fetch http://ppa.launchpad.net/skunk/pepper-flash/ubuntu/dists/xenial/main/binary-amd64/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead.
So I understand it has something to do with Pepper-flash, which I need for Chromium. Is this the reason why it âfails to connect to internetâ while updating? How can I fix it?
Thanks in advance!
I run Chromium and pepper-flash from our software sources. To install to browser...
sudo apt install pepperflashplugin-nonfree
You would need to remove the current skunk ppa.
If there is a problem with checking the agreement box, just press tab.
