It might be a bad disk. This can happen for new or existing installations.
To verify that your disk works properly you can use next commands:
This is my output from the above command
Disk /dev/sda: 238.47 GiB, 256060514304 bytes, 500118192 sectors
Disk model: Micron_1100_MTFD
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x65739f47
Device Boot Start End Sectors Size Id Type
/dev/sda1 * 2048 1050623 1048576 512M b W95 FAT32
/dev/sda2 1050624 500117503 499066880 238G 83 Linux
Now that we have identified our disk as /dev/sda we need to check for badblocks on that disk
Code:
sudo badblocks -sv /dev/sda
Note: that this process might take time for bigger disks!
If badblocks are detected we can try to fix them by running
