I had mysql-server installed, wordpress was working fine then I tried to install cyberpanel which failed installing mariadb

So I manually tried to install mariadb to know why it failed, it failed again and also broke my mysql, couldn't remove/purge it, couldn't reinstall it either no matter what I did,

After trying a few things here and there including creating backups and removing mysql dirs, now I cannot install anything, culprit being /tmp dir:

apt install x
E: Unable to mkstemp /tmp/clearsigned.message.PdV08H - GetTempFile (74: Bad message)
E: The package lists or status file could not be parsed or opened.

and more interestingly:

ls /tmp
ls: reading directory '/tmp': Bad message

I cannot install something to pull my data like vsftpd will also fail to install

Server is running Ubuntu 20.04

Update: checked dmesg and

EXT4-fs error (device loop0): __ext4_find_entry:1541: inode #2: comm lswsctrl: checksumming directory block 0

  • To fsck ext (aka e2fsck) the filesystem must not be mounted. See man 8 fsck.ext4. That's why the accepted answer to the linked question used a live USB. Before you unmount or reboot, let's investigate what /dev/loop0 is. What is the output of losetup -l /dev/loop0? Nov 6, 2021 at 23:58

I had the exact same issue, with Kamil's help, and following what is mentioned in this website, I could fix my problem. Just thought others might find it help
