When run this command sudo bench --site site1.local reinstall

Hi ERPNext Community
I want to do a re-install of my apps, but this problem appeared

I added the settings below to MariaDB’s my.cnf,and I restart MariaDB
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
default-character-set = utf8mb4
But to no avail
and when choosing another solution
“sudo git stash
sudo git reset --hard
sudo git pull --rebase”
This problem appeared, its want a GitHub account, and this account I don’t have, and I have to re-install the apps because there are problems with it.
Is there any solution ?
How can I go forward
I apologize that the translation has lost some details
Thanks everyone
