    Please help yourself and use descriptive thread titles.

    Open Update Manager and click Settings at bottom left. Click the Other Software tab. Look for an entry containing:

    http://www.duinsoft.nl

    Untick. Close. Try again.

    Hi enter this in terminal
    Code:
    sudo apt-key adv --recv-key --keyserver keyserver.ubuntu.com E18CE6625CB26B26
    Then update the system.
    With regards

    duinsoft.nl is repo for java ?

    looks like the key is

    Code:
    sudo apt-key adv --keyserver keys.gnupg.net --recv-keys 5CB26B26
    source:
    http://www.duinsoft.nl/packages.php

    Code:
    Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /tmp/tmp.GJa10MAv5F --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keys.gnupg.net --recv-keys 5CB26B26
    gpg: requesting key 5CB26B26 from hkp server keys.gnupg.net
    gpg: keyserver timed out
    gpg: keyserver receive failed: keyserver error

    I still vote for disabling the repo for now. See post #2. Could be a problem their end. Wonder if anyone else is having problems with the same key?

    There you go. Rules that out my idea the repo might be having problem and gives a clearer picture where to dig. Thanks oldos2er.
