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 bad ISO download, corrupted install media, or device failure. eg. look in the logs and you'll see messages like these :- Aug 12 07:24:43 ubuntu kernel: [ 242.141151] SQUASHFS error: zlib decompression failed, data probably corrupt Aug 12 07:24:43 ubuntu kernel: [ 242.141158] SQUASHFS error: squashfs_read_data failed to read block 0x2d7e90fe Aug 12 07:24:43 ubuntu kernel: [ 242.141424] SQUASHFS error: zlib decompression failed, data probably corrupt Aug 12 07:24:43 ubuntu kernel: [ 242.141427] SQUASHFS error: squashfs_read_data failed to read block 0x2d7e90fe Examining the information it appears to be a bad ISO or faulty device (inc. bad write-to-device). The bot reply refers to CD/DVD which refers to whatever media you installed from (ie. applies even if using HDD/SSD/thumb-drive/flash-memory-card/CD/DVD). I suggest you verify your ISO download, and validate the write of ISO to install media before trying to install.
