Getting curl command not found error while trying to install Mariadb

I am following a mariadb documentation in which the starting steps have been completed but when I use this command.

sudo curl -o /etc/apt/trusted.gpg.d/mariadb_release_signing_key.asc 
'https://mariadb.org/mariadb_release_signing_key.asc'

This command gives me an error:

sudo: curl: command not found

I have tried to install curl on my Ubuntu using these commands.

sudo apt update
sudo apt install curl

I am not sure whether it is installed now but it gives me the same error when i try to use the above command again.

For more understanding I am also adding the screenshot of some additional commands too.

Something went wrong during the installation of curl as it seems that your systems still misses it.

In order to check if the package curl is installed, you can try to run the following command:

apt-cache policy curl

Which should print something like this:

curl:
  Installed: 7.81.0-1ubuntu1.10
  Candidate: 7.81.0-1ubuntu1.10
  Version table:
 *** 7.81.0-1ubuntu1.10 500
        500 http://it.archive.ubuntu.com/ubuntu jammy-updates/main amd64 Packages
        500 http://security.ubuntu.com/ubuntu jammy-security/main amd64 Packages
        100 /var/lib/dpkg/status
     7.81.0-1 500
        500 http://it.archive.ubuntu.com/ubuntu jammy/main amd64 Packages

Update

If the package is correctly installed this command should show where the binary is

$ dpkg -L curl | grep bin
/usr/bin
/usr/bin/curl

Check the $PATH variable:

$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin

If it's not present, you can temporarily add /usr/bin to your $PATH variable with:

$ export PATH=/usr/bin:$PATH

To make this change permanent you can edit ~/.profile (user wide) or /etc/environment (system wide)

If everything else fails, you can always manually run the binary file using the full path:

$ /usr/bin/curl
curl: try 'curl --help' or 'curl --manual' for more information

The curl package seems to be broken, therefore reinstall the package with

$ sudo apt install --yes --reinstall curl

This will fix any missing binaries.

However, package binaries going missing is not a "normal" behavior. Someone or something must deliberately delete these files.
