ubuntu 16.04 svn commit, always enter password, pop-up window

16.04 The default mode of the svn password is: gpg-agent, which will be saved in the keychain. Although it is safe, it is very troublesome. When using automatic login, the keychain will not be automatically unlocked.

~/.subversion/config : Set the field password-stores = simple, the password will be saved in clear text under auth of this directory, and the password will not always be required.
