Installation of kubuntu 18.04 i386 fails to reboot

Bug #1761676 reported by Howard Moreland
This bug affects 1 person
Affects Status Importance Assigned to Milestone
ubiquity (Ubuntu)

Bug Description

At the end of installation, after clicking the Restart now button, GUI closes, screen shows "print_req_error: I/O error, dev loop0, sector 2420404" and lines for four more sectors. and "SQUASHFS error:squashfs_read_data failed to read block 0xbd54f4b" and lines for several more blocks. Continued repeating these lines for five minutes, then I did REISUB to reboot.Reboot is to text. Logging in and doing "startx" gets a graphical session that seems good. This is on a Lenovo X41 laptop.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Reviewing your log files attached to this bug report it seems that there is a problem with the disk to which you are trying to install Ubuntu. I'd recommend performing a back up of your existing operating system and then investigating the situation. Measures you might take include checking cable connections for your disks and using software tools to investigate the health of your hardware. In the event that is is not in fact an error with your hardware please set the bug's status back to New. Thanks and good luck!

There is a hardware problem. smartctl reports read error for the SSD.

However, Mint 18.3 installs to the system without any problem. Mint may not check for the error, or if Mint does see the error, it either ignores it or can work around it. A warning about the error would be nice to have, even if the read error does not interfere with installation.

Failing the installation on read error maybe kubuntu's design intent, in which case this is not a bug. Mint has a way to complete installation in spite of the faulty SSD.
