Thank you for taking the time to report this issue and helping to make Ubuntu better.
Examining the information you have given us, I see likely hardware issues that would explain it and wonder if you have a drive that needs examination (https://help.ubuntu.com/community/Smartmontools). For example lines like the follow appear many times :- Apr 21 07:14:21 ubuntu kernel: [ 126.439032] print_req_error: I/O error, dev sda, sector 268435376 Apr 21 07:14:21 ubuntu kernel: [ 126.439041] Buffer I/O error on dev sda, logical block 33554422, async page read This bug report can be converted to a question (which is aimed at support). You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community- support/709 I've marked this bug incomplete as normal support steps don't appear to have been tried, or evidence of them hasn't been provided. If you believe I'm in error, or can provide additional detail of steps done, please change status back to "New" and leave comment, or additional information as to what was attempted. Thanks again for helping make Ubuntu better. ** Changed in: grub-installer (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874026 Title: Installing over the top of existing 1804 onto an M2 drive To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1874026/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
