Failed to search for file: Failed to download gpg key for repo 'mariadb-main': Curl error (37) showing up in terminal

mahaju · 05-11-2020, 02:32 AM

I installed MariaDB on a computer with CentOS using the instructions given here: https://mariadb.com/kb/en/mariadb-pa...tup-and-usage/

The basic command I used was

Code:

sudo yum install MariaDB-server MariaDB-client

and I did not install Maxscale or percona

Mariadb installed successfully, but now when I go to the terminal and type in a command that doesn't exist, I get a "Failed to download gpg key" error message.

For example, when I type in ftp and press enter, previously I would have got a message indicating that ftp was not installed, and I would have got some recommendations on which command I meant and would like to download. However, now I get this:

Code:

[username@localhost ~]$ ftp  
bash: ftp: command not found...  
Failed to search for file: Failed to download gpg key for repo 'mariadb-main': Curl error (37):     Couldn't read a file:// file for file:///etc/pki/rpm-gpg/MariaDB-Server-GPG-KEY [Couldn't open file   /etc/pki/rpm-gpg/MariaDB-Server-GPG-KEY]  
[username@localhost ~]$

I understand this is because because the file etc/yum.repos.d/maradb.repo has an entry gpgkey = file:///etc/pki/rpm-gpg/MariaDB-Server-GPG-KEY and the MariaDB-Server-GPG-KEY file does not exist in etc/pki/rpm-gpg

I think this file should have been copied to this location automatically when I installed Mariadb, but didn't for some reason. Is there a way I can create or download this file manually to make this error message go away?

Code:

sudo rpm --import https://downloads.mariadb.com/MariaDB/MariaDB-Server-GPG-KEY

I still get the same error. etc/pki/rpm-gpg does not have the MariaDB-Server-GPG-KEY file. Opening https://downloads.mariadb.com/MariaD...Server-GPG-KEY in browser gives me a 404 not found page

Check your internet connection then. I can download it no problem. Does this also not work?

Code:

sudo rpmkeys --import https://downloads.mariadb.com/MariaDB/RPM-GPG-KEY-MariaDB

This command doesn't return anything but I still get the GPG file not found error.

Incidentally I was able to download the MariaDB-Server-GPG-KEY from a browser, I'm not sure why it didn't work earlier. But I have this file now. Can I simply copy it into /etc/pki/rpm-gpg ?

No, better install it properly

Code:

sudo rpmkeys --import MariaDB-Server-GPG-KEY

This gives me

Code:

error: MariaDB-Server-GPG-KEY: import read failed(2).

I get this error message when trying to import a key from a non-existing file. Have you run it from the same directory where you downloaded the key? If not then it should have been

Code:

sudo rpmkeys --import /path/to/the/downloaded/MariaDB-Server-GPG-KEY

I changed to the folder where I downloaded the MariaDB-Server-GPG-KEY file and tried sudo rpmkeys --import MariaDB-Server-GPG-KEY

The command does not return any errors but I still get the "Failed to download GPG error"

The /etc/pki/rpm-gng folder still does not have a MariaDB-Server-GPG-KEY file

Then just put this into /etc/yum.repos.d/mariadb.repo

Code:

gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

Is it safe to do this? What is the difference between RPM-GPG-KEY-MariaDB and MariaDB-Server-GPG-KEY? What is it actually doing internally?

I just copied it from their repository generator, so I suppose it's safe.
