I did "apt-get update" then "apt-get upgrade" but no pop message appeared instead

The following packages have been kept back: koha-common

That means one of a couple of things, but the essential bit is that Debian isn't upgrading it for some reason. Most often you see it when the package has been manually held for some reason, although I expect that you'd know if that were the case. The other is that that apt is uncomfortable about installing the new dependencies. If this is the case, try: aptitude upgrade which will usually ask you about them (although I would have expected apt to do this also), or: apt-get dist-upgrade which tells apt that you're OK with it making slightly bigger changes. You could also try: apt-get install koha-common which may force it to override the holding. Let me know how you get on. -- Robin Sheat Catalyst IT Ltd. ✆ +64 4 803 2204
