Thank you for taking the time to report this issue and helping to make Ubuntu better.
This failure as you describe it (squashfs problem) reads like a bad download or bad write to install media (where you get /dev/sr0 read failures). If you look in your (missing) logs it'll have messages like the following (from another like report, not yours as yours were not attached) :- Jun 26 10:37:24 ubuntu kernel: [ 363.074612] SQUASHFS error: zlib decompression failed, data probably corrupt Jun 26 10:37:24 ubuntu kernel: [ 363.074615] SQUASHFS error: squashfs_read_data failed to read block 0x76d9b3d5 Possibly useful : https://tutorials.ubuntu.com/tutorial/tutorial-how-to- verify-ubuntu#0 and https://help.ubuntu.com/community/Installation/CDIntegrityCheck In your case I'd suggest you validate your ISO, and install-media (thumb-drive, cd, dvd or whatever you use which is referred to as CD) then try again. -- 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/1854427 Title: installation failed Status in linux package in Ubuntu: Incomplete Bug description: The installation for ubuntu 18.04 and 19.10 failed on laptop called dc pro as in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1751990 for ubuntu 16.04.03 and 16.04.06 (should have same problem on 04 and 05) on 18.04 the problem is the same as 16.04.03+ the moving 5 dots will stop and system hang on 19.10 it will eject the disk and print something like nouveau problem /dev/sr0 read problem squashfs problem I think the problem occured before that since the 5 dots stop moving and cdrom stopped then both restart then cdrom rejected and print out above message To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1854427/+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
