    We are trying to set up a a repo Sever for all the distro we have, and we would like to add also the ubuntu repos.
    I'm newbie working with repos and basically the easiest way to mirror the ubuntu repos without using debian command like apt-mirror is using rsync, but doing that i will copy all the ubuntu repos and I would use a lot of space, while I would need only the repos for the the trusty and xenial distro.
    There is a way to do it? or simply i need to copy all or forced to make the mirror using apt-mirror with ubuntu

    No problem :-)

    We have to sent the MacBook to get repaired and for security reason we "must" wipe out the disk. When will have the MacBook back i'll have to reinstall.....and we'll see how :-). I never worked with apple product so....but first step i have to wipe out. This Macbook has an SSD
    Reading some article an some post on various forum seem not necessary to wipe out an SSD because of how it works and also because doing that we reduce the life of the SSD itself, I saw that there are specific product to securely erase SSD(Blancco and Parted Magic) but they are not free and i don't know if i can build a bootable disk with that product for a Mac.

    In this moment i have two choice

    • 1): Start MacOS in recovery mode and form diskutil run a normal erase(i don't have the "Security Option" ). I read that the security erase is still place in the command line version of diskutil but i don't know how to do it work. Even from the GUI version i don't undestand how the partitions are configured and what i have to delete:
      Using Disk utility form the GUI i saw this:

    */dev/disk0 (internal, physical):
    #: TYPE NAME SIZE IDENTIFIER
    0: GUID_partition_scheme 251.0 GB disk0
    1: EFI EFI 209.7 MB disk0s1
    2: Apple_APFS Container disk1 250.8 GB disk0s2
    /dev/disk1 (synthesized):

    #: TYPE NAME SIZE IDENTIFIER
    0: APFS Container Scheme - +250.8 GB disk1
    Physical Store disk0s2
    1: APFS Volume Macintosh HD 28.5 GB disk1s1
    2: APFS Volume Preboot 18.8 MB disk1s2
    3: APFS Volume Recovery 506.6 MB disk1s3
    4: APFS Volume VM 1.1 GB disk1s4*

    and i don't know how interpret the structure of the partitions, What is Disk0 and Disk1? Disk0 is the physical Disk and Disk 1 is a kind of virtual disk inside Disk0? what i would do to run diskutil secureErase ?

    • 2) Boot from a Linux Live Usb and Run this command: for i in $( seq 0 2 ); do dd if=/dev/urandom of=/dev/sda; done or using the command wipe or shred risking to reduce the life of the SSD

    Any Advice is welcome :-)

    In Diskutility it miss the "Security Options" and if i have undestand is for the reason below:

    "Note: With an SSD drive, Secure Erase and Erasing Free Space are not available in Disk Utility. These options are not needed for an SSD drive because a standard erase makes it difficult to recover data from an SSD. For more security, consider turning on FileVault encryption when you start using your SSD drive."

    I need to wipe out the Disk where is the Sierra OS so i would need to boot from another disk? or i can use the disk utility after pressing <cmd>-<R> at the boot..

    Could you help me to find a good tools (commercial or freeware) that can help to recover some data from a Damaged HDD?
    Sometimes we used testdisk to recover partition but mainly it works well to recover deleted files.
    One friend told me that use that MacOS with a freeware tools(i have still to ask which tools)

    He told me that, instead of Windows that sometimes it block itself when is passing through some broken cluster, MacOS go forward.....and even if at the end could say that was impossible to recover all, at least is possible to analyse the entire disk.

    Any Advice??

    We have some worksation\laptop that where offline fot months, but before to put online they asked to perform some offline updates, the Antivirus which i did and the OS as best as i can with the latest security patches released by microsoft.

    I tried to use a famous tools WSUSOFFLINE to download patches but seems that does not download any patches (except for the static ones enumerated in a file). do you have never used WSUS OFFLINE?

    There is any other method that permit to download the Security patches? without downloading one by one from Windows Catalog?
