Hi,

I am suddenly getting lots of GPG NO_PUBKEY error messages when trying to do a 'sudo apt-get update'. I have not changed or done anything that should be causing this. The errors are:


W: GPG error: http://apt.insynchq.com wily InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 06BBDC2602DFE7E7
W: GPG error: http://dl.google.com stable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A040830F7FAC5991

W: GPG error: http://repo.vivaldi.com stable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY CEC384A8BF1700F8

I have tried to add the keys with 'sudo gpg --keyserver keyserver.ubuntu.com --recv-keys XXXXXXXXXX' but it doesn't fix the problem. The same errors are back again next time I do an update. This is the typical output I get when trying to add them:


gpg: requesting key 437D05B5 from hkp server keyserver.ubuntu.com
gpg: key 437D05B5: "Ubuntu Archive Automatic Signing Key <ftpmaster@ubuntu.com>" not changed
gpg: Total number processed: 1
gpg: unchanged: 1

What can I do to fix this problem? Since I haven't made any changes to my computer myself I have no idea how or why this happened.
