I'm having this same issue with ubuntu-16.04.1-desktop-amd64.iso The md5 of the downloaded file is correct, and if I make an iso of the recorded dvd the md5 matches also. Furthermore, if I mount the iso on linux and check the md5sums inside the iso, they all match.
The problem, however, is when booting the dvd from an external dvd writer. The first times it worked, however after several times it started failing and did ever since. The usb dvd writer is in perfect condition because mounting the disk on linux also verifies the checksums. However, if I perform the integrity check booting from the external usb writer it says 1 file failed but doesn't specify which one!!!! what crap is this!! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/172937 Title: SQUASHFS error while booting from live cd Status in linux package in Ubuntu: Won't Fix Status in linux package in Fedora: Won't Fix Status in linux package in Mandriva: Invalid Bug description: Some users have reported being unable to boot from the Ubuntu LiveCD, due to SquasFS errors like this: [ 135.292409] SQUASHFS error: sb_bread failed reading block 0x9d7f3 [ 135.292411] SQUASHFS error: Unable to read fragment cache block [275faa28] [ 135.292413] SQUASHFS error: Unable to read page, block 275faa28, size 23a7 These errors can be due to a variety of reasons: * bad media (solution: try burning the iso image to a new disc) * a bad dvd drive (solution: if possible, try using a different cd/dvd drive) * bad memory modules (solution: use memtest86+ to check your memory) * a corrupted iso image (solution: run an md5 checksum, and if they don't match, download the iso image again) * an optical drive connected via SATA instead of PATA and running in Enhanced mode (solution: change the IDE configuration to "compatible" in the BIOS) This is all described in more detail here: https://help.ubuntu.com/community/SquashfsErrors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/172937/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
