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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1854427 Title: installation failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1854427/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
