I already have mysql-server
package installed!!!
I want to make sure I have the most recent MySQL in my Ubuntu. So (long time ago) I added repo.mysql.com/apt/ubuntu
PPA. Recently I noticed errors related to this repository when doing apt update
. Following this guide I've downloaded and imported public GPG key.
Now when I do sudo apt update
I get this error:
Err:8 http://repo.mysql.com/apt/ubuntu cosmic InRelease
The following signatures were invalid: EXPKEYSIG 8C718D3B5072E1F5 MySQL Release Engineering <mysql-build@oss.oracle.com>
OS information: Ubuntu 18.10
Should I worry about this invalid signature? How to fix the error?
