I'm already too tired of trying so many different things and I can't even bypass an error which is running. I know some of you might think it's a duplicate question, but I've seen dozens of questions, so I don't think the answer is so simple, nor is duplicated.
This are some of the many solutions I unsuccessfully tried:
update command is denied for user
Can't change user password on MySQL using UPDATE
Error: select command denied to user '<userid>'@'<ip-address>' for table '<table-name>'
MySQL Error: #1142 - SELECT command denied to user

# mysql -u root -p
when it asks for password, no matter what I type it shows

when I type
MariaDB [(none)]> use mysql;
ERROR 1044 (42000): Access denied for user 'root'@'%' to database 'mysql'
Notice it says %
instead of localhost, is that a hint of something going on? have you encountered the same problem and were able to solve that?
even if I type the right password. I have another user but I can't change its password.
MariaDB [(none)]> select user, plugin from user;
shows
ERROR 1046 (3D000): No database selected
I feel like I really tried everything, I mean I've been like this for so many hours now, and I've changed mysql passwords many times in the past, using console in windows and linux, I have no idea what's going on!
EIDT: as suggested in comments here is the output for SELECT user, host, plugin from mysql.user;
MariaDB [(none)]> SELECT user, host, plugin from mysql.user;
