Apart of the issue with update-initramfs, I see lot's of I/O error in combination with time outs, like: Feb 6 07:13:08 ub01 kernel: [6640939.527399] sd 478:0:0:1: timing out command, waited 180s Feb 6 07:13:08 ub01 kernel: [6640939.527483] blk_update_request: I/O error, dev sdhb, sector 4609920 Feb 6 07:13:08 ub01 kernel: [6640939.527526] blk_update_request: I/O error, dev sdhb, sector 4610032 Feb 6 07:13:08 ub01 kernel: [6640939.527536] blk_update_request: I/O error, dev sdhb, sector 2048 Feb 6 07:13:08 ub01 kernel: [6640939.527546] blk_update_request: I/O error, dev sdhb, sector 2056 Feb 6 07:13:08 ub01 kernel: [6640939.817404] sd 376:0:0:1: timing out command, waited 180s Feb 6 07:13:08 ub01 kernel: [6640939.827388] sd 494:0:0:1: timing out command, waited 180s There seem to be issues with your storage and/or storage sub-system.
