Why can I not deselect "encrypt my home folder"?
I tried to install Ubuntu 13.04, but didn't want to encrypt my home folder. The installer doesn't let me uncheck the option.
Why?
Are you upgrading a previous install (or using an existing Home partion)?
If so this is most probably because you previously installed Ubuntu with an encrypted home folder. The installer automatially detects this. You cannot unset "Encrypt my home folder" as you would not be able to access your files otherwise.
It is very important that you select the same login password as before. If needed you can change it after the instalation.
