SQLite: Attempt To Write A ReadOnly Database – SVN E155004 & E200031

When trying to update SVN code from a Subversion repository, you get this error:

svn: E155004: Working copy ‘C:\Data\Prover’ locked
svn: E200031: sqlite: attempt to write a readonly database
svn: E200031: sqlite: attempt to write a readonly database
svn: run ‘svn cleanup’ to remove locks (type ‘svn help cleanup’ for details)

When you run SVN cleanup as suggested in the error, you get this error:

svn: E200031: sqlite: attempt to write a readonly database
svn: E200031: sqlite: attempt to write a readonly database

The sqlite: attempt to write a readonly database error is because you don’t have the NTFS permissions required to write to the directory containing the files that you are trying to update. Try explicitly adding your account name to the NTFS permissions with Full or Modify access, or run as an administrator.
