Thank you for taking the time to report this issue and helping to make Ubuntu better.
This package failure looks like it was caused by a corrupted file system, or device failure. eg. look in the logs and you'll see messages like these :- Jul 12 01:31:22 ubuntu kernel: [ 201.764811] SQUASHFS error: zlib decompression failed, data probably corrupt Jul 12 01:31:22 ubuntu kernel: [ 201.764815] SQUASHFS error: squashfs_read_data failed to read block 0xe81c6e3 Jul 12 01:31:22 ubuntu kernel: [ 201.765971] SQUASHFS error: zlib decompression failed, data probably corrupt Jul 12 01:31:22 ubuntu kernel: [ 201.765973] SQUASHFS error: squashfs_read_data failed to read block 0xe81c6e3 Examining the information you have given us, this does not appear to be a useful bug report so I am closing it, as it appears to be a faulty device (or bad write-to-device). If you believe I'm in error, please leave a comment explaining why and change the status back to 'new'. I suggest you use the 'check disc for defects' option to validate your media before install to ensure a good download & write. ** Changed in: ubiquity (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1836284 Title: crash during installation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1836284/+subscriptions -- ubuntu-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
