TASK ERROR: command 'systemctl start pve-container@102' failed: exit code 1

I executed this command apt update && apt upgrade. After that, all container start except the ftp container. Launch this error: Job for [email protected] failed because the control process exited with error code. See "systemctl status [email protected]" and "journalctl -xe" for details. TASK ERROR: command 'systemctl start pve-container@102' failed: exit code 1. When I execute the command "systemctl status [email protected] this is what showed: And the command journalctl -xe showed:

How can I fix it?

Line 6 in your second debug-window says
EXT4-fs (dm-9): error loading journal
Something is wrong with the EXT4 file-system in your container.

Try to fsck it!

Note1: Make sure the container image is not mounted before running fsck.
Note2: In case the fs contain important data, backup the image file before you proceed.

Try to fix the journal:
e2fsck -E journal_only /path/to/your/container_image.raw

...or do a regular fsck on the whole ext4 fs:
e2fsck /path/to/your/container_image.raw

If faults are found, and fsck think it can fix them, answer yes to the suggested fixes. Hopefully the container can now start up.
