Thank you for your reply, Adam. I analysed your log files a little bit and I noticed something that may be the root cause of your problems here. Your DpkgTerminalLog.txt file contains the following excerpt:
... Paramétrage de mysql-server-8.0 (8.0.26-0ubuntu0.20.04.2) ... mysqld: Error on realpath() on '/home/adamSQL/Documents' (Error 2 - No such file or directory) mysqld will log errors to /var/log/mysql/error.log Warning: Unable to start the server. Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details. ... Note the "mysqld: Error on realpath() on '/home/adamSQL/Documents' (Error 2 - No such file or directory)" message. Upon inspecting your mysql.cnf, I saw this line: secure_file_priv = /home/adamSQL/Documents The "secure_file_priv" option is used to limit the effect of data import and export operations. According to MySQL's manual: If set to the name of a directory, the server limits import and export operations to work only with files in that directory. The directory must exist; the server does not create it. In your case, the directory /home/adamSQL/Documents doesn't exist. I am assuming that you explicitly added the "security_file_priv" option to your mysql.cnf, and that you understand what it does. It seems like you just need to re-create the /home/adamSQL/Documents directory and try to start the service again. I am almost sure that this is not a bug but rather a local configuration issue. I will set the status to Incomplete again; feel free to revert it back to New if/when you have more information about the issue. Thank you. ** Changed in: mysql-8.0 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1939395 Title: package mysql-server 8.0.26-0ubuntu0.20.04.2 failed to install/upgrade: circular symlink to configuration file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1939395/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
