Been on forums trying various fix's no luck yet. Have direct network no proxy. Tried again after full backup with clean install as before on first boot up update manager shows blue icon. Action that new mint update available, download this, prog closes, opens instantly with number of updates firefox thunderbird libre office etc.
System working at this point, but after this update back to the "failed to fetch situ.
Is the mint update the issue?
Apart from this Mint works fine email browser rss etc.
Should add apt-get synaptic all show same failed to fetch prob so no software additions
