Fsck problem: the root filesystem on /dev/sda5 requires a manual fsck

fo flag

My Ubuntu computer says /dev/sda5 contains a file system with errors, check forced. /dev/sda5: Inode 393249 seems to contain garbage.

/dev/sda5: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. (i.e., without -a or -p options) fsck exited with status code 4 the root filesystem on /dev/sda5 requires a manual fsck

BusyBox v1.30.1 (Ubuntu 1:1.30.1-4ubuntu6.4) built in shell (ash) Enter 'help' for a list of built-in commands.


How do I fix this?

Boot from **another** linux system, typically from a USB drive with Ubuntu running live 'Try Ubuntu'; Identify the problematic drive, if it is still seen as `/dev/sda5` and run `sudo e2fsck -cf /dev/sda5` and if there are lots of error messages maybe according to the automatic advice `sudo e2fsck -p /dev/sda5`; See more details at `man e2fsck`

Does this answer your question? [fsck error on boot: /dev/sda6: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY](

If you boot from an Ubuntu USB drive, there is sudo. Do not try this from the system that you want to repair.

It seems that your Ubuntu computer has encountered file system errors on the /dev/sda5 partition. The error message suggests running fsck (file system check) manually to fix the issue. Here are the steps you can follow to resolve this problem: Start by rebooting your computer. When the GRUB bootloader screen appears, select the advanced options for Ubuntu. From the advanced options menu, choose the recovery mode option for your Ubuntu installation. This will boot your system into a recovery environment. In the recovery menu, select the "root" option to drop into a root shell prompt. Once you're in the root shell prompt, run the following command to check and repair the file system on /dev/sda5:

fsck /dev/sda5

If prompted, you can respond with "y" to fix any errors automatically. After the file system check and repair process is complete, run the following command to reboot your system:


Allow your system to boot normally and see if the issue has been resolved. Running fsck manually should help fix any file system errors on the /dev/sda5 partition. However, it's important to note that this process may take some time to complete, depending on the size of the partition and the extent of the errors.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
