Ubuntu – How to set chroot for SFTP under Ubuntu 8.04

scponly is a hack. The built-in sftp-server with chroot was meant to address this need properly.

Ben, why do you want them to see their home as /home/user? Doesn't that kind of defeat the purpose of a chroot? Is it just pwd output that you're looking for to reflect their location?

Or is it so they can use full paths in a script? I think you could symlink /home/user/home/user to /home/user for those purposes.

The command apt-get upgrade will not add or remove packages. apt-get dist-upgrade will add or remove packages as required.

The command apt-get dist-upgrade will not automatically upgrade you from one release to another unless you have also updated your sources (/etc/apt/sources.list) to point at a newer release.

man apt-get

upgrade
    upgrade is used to install the newest versions of all packages 
    currently installed on the system from the sources enumerated 
    in /etc/apt/sources.list.

dist-upgrade
    dist-upgrade, in addition to performing the function of upgrade, 
    also intelligently handles changing dependencies with new versions 
    of packages;

Are there special concerns to be aware of when doing a dist-upgrade vs upgrade?

For the most part I always apt-get dist-upgrade to apply updates to a system. Of course pay attention to exactly what new packages are being added or removed. Frequently this happens when something is being added like a newer kernel that isn't compatible with the previous and you will have to recompile modules. If you have some kernel module you had to build on your own, then you may need to make sure you recompile it for the new kernel. I have a couple systems with network interfaces not supported by the stock kernel that I have to recompile the network driver after each kernel update.
