Since installing Mint 11 (katya) LXDE 32bit over Linpus on my wife's AOO, she's never had an update, even though the green tick tells her she's up to date. I tried updating manually through Update Manager. It initially downloaded lots of updates then gave a huge list of things it couldn't do and ended up updating nothing. I noted a lot of the problems related to not finding the linux mint server so I followed the instructions from the post -
viewtopic.php?f=90&t=122213 - "Trouble updating? Solution provided here" by xenopeek and changed to a server in the Netherlands, even though I'm in the UK, but this was the best recommended. Trying again, it downloads but ends with this dialogue - see attachment - and nothing is there for update. The green tick is still there. I'm confused

Any help appreciated.
