I reimaged my install stick, then tried the installation (install USB -> destination USB) on a bigger and faster computer. It worked fine the second time.
I made the first attempt on a repurposed Asus CR-16 Chromebook that had been upgraded to 8 Gb memory and 128 Gb SSD, and the second on an ASRock X99 Extreme based build (6 Core Intel server CPU, 64 Gb error correcting memory). Perhaps the install simply needed more memory, though I cannot see why. Thank you so much. -- Eric On Wed, Aug 12, 2020 at 8:31 AM MADUPOJU SANJAY KUMAR < 1874...@bugs.launchpad.net> wrote: > I'm unable to install > > -- > You received this bug notification because you are subscribed to a > duplicate bug report (1891170). > https://bugs.launchpad.net/bugs/1874662 > > Title: > Corrupted installation medium > > Status in Ubuntu: > Fix Released > > Bug description: > > If you have been redirected to this page, it means that your > installation of Ubuntu or a flavour failed. > > If you search in the log file /var/log/syslog, you'll see messages > like above: > > Apr 24 00:01:40 ubuntu kernel: [ 329.409695] SQUASHFS error: zlib > decompression failed, data probably corrupt > Apr 24 00:01:40 ubuntu kernel: [ 329.409704] SQUASHFS error: > squashfs_read_data failed to read block 0x37545 > > This failure is usually caused by bad ISO download, corrupted install > media, or device failure. > > We suggest you verify your ISO download, your installation medium or > use another USB stick. > > You may also find useful information in this tutorial: > https://tutorials.ubuntu.com/tutorial/tutorial-how-to-verify-ubuntu > > If you experienced an issue during installation and think it is not > caused by a corrupted installation media, do not hesitate to report a > bug by running the following command from a terminal: > > $ ubuntu-bug ubiquity > > Thanks for using Ubuntu. > > > [Do not close or re-assign this report] > [It's used to help users using faulty USB sticks] > > To manage notifications about this bug go to: > https://bugs.launchpad.net/ubuntu/+bug/1874662/+subscriptions > -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874662 Title: Corrupted installation medium To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1874662/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
