    want checksum of xubuntu 20.04 iso

    i would like to get a checksum (md5, sha256, etc) of the xubuntu 20.04 (focal fossa) LTS iso image to verify my download. the xubuntu.org web site didn't have it. otherwise i will download it from 3 or more sites and cross check it.

    https://kubuntu.org/alternative-downloads

    Use zsync from the folder you have your ISO in.
    You will need to find correct path for xubuntu. Probably:
    http://cdimage.ubuntu.com/kubuntu/re...20.04/release/

    this is my Ubuntu
    zsync http://releases.ubuntu.com/focal/ubuntu-20.04-desktop-amd64.iso.zsync

    I often change to a local repository once released.

    When they released Ubuntu, I changed daily name to release file name & zynced it.

    Rename daily from Monday & it was 91% the same:
    fred@Z170N-focal:~/ISO$ zsync http://releases.ubuntu.com/focal/ubu...md64.iso.zsync

    #################### 100.0% 2711.6 kBps DONE

    reading seed file ubuntu-20.04-desktop-amd64.iso:

    Read ubuntu-20.04-desktop-amd64.iso. Target 91.0% complete.
    downloading from http://releases.ubuntu.com/focal/ubu...top-amd64.iso:
    #################### 100.0% 7988.2 kBps DONE

    You find your MD5SUM at the following link (along with the other released Xubuntu files),

    cdimage.ubuntu.com/xubuntu/releases/20.04/release/

    You can navigate to all released ISO files and other files of Ubuntu desktop and Ubuntu family flavours via the following link,

    releases.ubuntu.com/

    Re: want checksum of xubuntu 20.04 iso

    The zsync automatically does the chksum.
    It only downloads changes, if you already have the ISO.

    Used primarily for daily release of the next Ubuntu, so you an test.

    Re: want checksum of xubuntu 20.04 iso

    i get no response from the cdimage.ubuntu.com (91.189.92.164) server. not even a ping. it must be way overloaded.

    Code:
    lt2a/forums /home/forums/iso 43> time zsync http://releases.ubuntu.com/focal/xubuntu-20.04-desktop-amd64.iso.zsync
    failed on url http://releases.ubuntu.com/focal/xubuntu-20.04-desktop-amd64.iso.zsync
    could not read control file from URL http://releases.ubuntu.com/focal/xubuntu-20.04-desktop-amd64.iso.zsync

    looks like they don't have the zsync control file there for Xubuntu.

    Re: want checksum of xubuntu 20.04 iso

    I've never had a problem going to cdimage.ubuntu.com and didn't just now. All the checksums are on this page along with the ISOs:

    http://cdimage.ubuntu.com/xubuntu/re...20.04/release/

    The file http://cdimage.ubuntu.com/xubuntu/re...ase/SHA256SUMS contains the same signature you report above.

    Code:
    005a9450d16fe885132be9368a96c73910096b57cc1a67f03a97fca7af95f4a3 *xubuntu-20.04-desktop-amd64.iso
    If you ask for help, do not abandon your request. Please have the courtesy to check for responses and thank the people who helped you.

    Re: want checksum of xubuntu 20.04 iso

    so, i need a different site which has xubuntu (i'm not trying to get kubuntu) and that zsync file. or just the plain sha256. i have already downloaded the whole iso. the sha256 of it is 005a9450d16fe885132be9368a96c73910096b57cc1a67f03a 97fca7af95f4a3.
