Ubuntu 16.04 On Choosing an Repository I have 3 choices for this country and all gave this error. Could not download all repository indexes  The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct. An error occurred during the signature verification. The repository is not updated and the previous index files will be used.

What is the best way to renew a gpg key pair when it got expired and what is the reason for the method?  The key pair is already signed by many users and available on public servers.   Should the new key be a subkey of the expired private key?  Should it be signed by the old (I could try to edit the key and change the date of expiration to tomorrow)? Should the new key sign the old?

I'm trying to do an apt-get update or apt-get install xyz and I'm seeing timeouts like this:  W: Failed to fetch http://eu-west-1.ec2.archive.ubuntu.com/ubuntu/dists/oneiric-updates/Release.gpg   Unable to connect to eu-west-1.ec2.archive.ubuntu.com:http: [IP: 10.224.87.159 80]   Is this a transient issue with Ubuntu, or maybe it's something on my end. The box I'm accessing it from is in EC2-EU.  Perhaps there is a way to force the installer to use the US servers which seem to work?

I'm a new user of Ubuntu 13.10.  I recently tried to resolve a Skype installation issue and added some PPA involving binary-1386.  Every time I run sudo apt-get update, I get the following error:  W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/saucy/Release  Unable to find expected entry 'restricted/binary-1386/Packages' in Release file (Wrong sources.list entry or malformed file) W: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/saucy/Release  Unable to find expected entry 'main/binary-1386/Packages' in Release file (Wrong sources.list entry or malformed file) ... ... E: Some index files failed to download. They have been ignored, or old ones used instead.   I have spent the last two hours trying to resolve this issue, and made changes to my sources.list file by resetting to.the default saucy settings, but these errors are still occuring.  I've also unchecked everything in Software and Updates section, but this still seems to appear.  The error messages seem to be related to the 'binary-1386/Packages' in Release file (Wrong sources.list entry or malformed file) issue as shown above.

Just updated to 20.04 final release, and I'm seeing these messages in /var/log/auth.log...

All my 20.04 systems are missing this file. Two 20.04 installations are upgrades, and one installation is a fresh install VM. What's up with this file missing in 20.04? Should I restore a copy from 19.10? Update #1: The same problem occurs in 20.10, in both upgrades and fresh installs.

After a reinstall of Ubuntu 12.04 ,it's impossible to install commercial games, e.g Oil Rush. It gives this error:  Failed to fetch https://private-ppa.launchpad.net/commercial-ppa-uploaders/oilrush/ubuntu/dists/oneiric/main/binary-amd64/Packages  The requested URL returned error: 401 Failed to fetch https://private-ppa.launchpad.net/commercial-ppa-uploaders/oilrush/ubuntu/dists/oneiric/main/binary-i386/Packages  The requested URL returned error: 401 Some index files failed to download. They have been ignored, or old ones used instead.   I bought these games in 11.10, but I installed these games in 12.04 before... How can I solve this problem?

I've noticed that running apt-get update recently has resulted in quite a few ppa's returning "403 Forbidden".  In and effort to clean them up I had a look:  W: Failed to fetch http://ppa.launchpad.net/gnome3-team/gnome3/ubuntu/dists/raring/main/binary-amd64/Packages  403  Forbidden  W: Failed to fetch http://ppa.launchpad.net/gnome3-team/gnome3/ubuntu/dists/raring/main/binary-i386/Packages  403  Forbidden  E: Some index files failed to download. They have been ignored, or old ones used instead.   The strange things is, if I copy these URLs into my browser I can access the files just fine.  Why would apt-get report "403 Forbidden" if they're still accessible?  I tried re-adding the ppa through add-apt-repository which downloads the signing key again, and it still reported "403 Forbidden".

I have a crazy problem. Whenever I update anything I get this error     update for (insert Google app here) could not be downloaded due to an error (error while retrieving information from the server. [RPC:S-7:AEC-7 QNHM-TYSO-UNVHY])   It may also be worth telling you the very last 5 letters vary. It also happens to any new apps I attempt to install.
