[SOLVED] Did I mess up my partitions?

Twice now I have gotten an error on boot that says

 kernel: FAT-fs (nvme0n1p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
 systemd[1]: Mounted /boot. 

I run lsblk and this is what my partitions look like.

 NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
zram0       253:0    0     4G  0 disk [SWAP]
nvme0n1     259:0    0 476.9G  0 disk 
├─nvme0n1p1 259:1    0     1G  0 part /boot
├─nvme0n1p2 259:2    0    47G  0 part /
└─nvme0n1p3 259:3    0 428.9G  0 part /home 

How badly have I messed up? my system is running fine but I need to update and I am scared to do anything without fixing this.

Normal EFI/FAT warning. /boot wasn’t cleanly unmounted.
Boot a live USB and run:

fsck.vfat -a /dev/nvme0n1p1

Reboot.

Thank you! I couldn't remember what I had done the first time but this is the answer. Closing the topic, but I am curious if you know if there a reason it's failed to cleanly unmount twice now? Is there something I can do to prevent the issue from happening again?

Re: [SOLVED] Did I mess up my partitions?

It usually happens if the system shuts down or reboots before /boot is unmounted, not pirticularly how but happens mostly when forced shutdown or power loss . To prevent it, just let shutdowns finish normally and avoid forcing power off. Once /boot is clean again, it’s unlikely to cause any problems.

Ok that was my working theory, thank you for confirming!
