    I upgraded an old ISPConfig2 server from Debian Lenny to Debian Squeeze. Everything went fine, except one issue:
    openssh-client openssh-server can not be upgraded.

    This is what happens:

    apt-get upgrade
    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    The following packages will be upgraded:
    openssh-client openssh-server
    2 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
    Need to get 0 B/1,252 kB of archives.
    After this operation, 123 kB of additional disk space will be used.
    Do you want to continue [Y/n]? Y

    E: Sub-process /usr/bin/dpkg returned an error code (1)

    What is the recommended way to solve this problem?

    Using this as base: http://forums.debian.net/viewtopic.php?p=160255

    It might be, that the ssh binaries are marked / flagged to allow appending only (-a) or or may not be changed (-i).

    So you might list the attributes with lsattr and remove the ones with chattr (see posts in the link above or as an example the following commands):

    @Ben,
    Thank you! That was my problem indeed. I just upgraded openssh-client openssh-server succesfully.
