Can't remove mysql completely

cn flag

I tried many times to completely remove MySQL from my system without success. I get these errors:

Photo error 1

Photo error 2

I also tried other commands without success. What should I do?

Here is the output of apt list --installed | grep mysql:

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

Here I am inside /var/lib/dpkg/info/ and I searched for "mysql" and I see these files:

Should I delete them or is it a bad idea? If I delete them, will I be able to uninstall everything related to MySQL?

Using this command:

sudo apt purge mysql-server mysql-client mysql-common mysql-server-core-* mysql-client-core-*

I get this error:

To completely remove a package, we can use the apt purge command with arguments such as --autoremove to clear off the dependencies along with their parent packages. In your specific case, I don't think apt purge will work as dpkg is throwing errors with the pre-installation script. It seems like you have manually removed some files or directories.

  • Use the dpkg command with the -P argument to forcefully purge the package.

For forcefully purging the package.

  1. Since removing packages can be destructive, print the list of the package that will be removed:

    dpkg -l | awk  '{print $2}' | grep -i mysql | grep -v lib

    Check if any important package is being removed. If everything seems fine, proceed to step 2.

  2. Purge the packages:

    sudo dpkg -P  --force-all $(dpkg -l | awk  '{print $2}' | grep -i mysql | grep -v lib)

This should completely remove MySQL. Then run a force install:

sudo apt -f install

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.
