之前提示更新，但进度条一直无法启动，换多个浏览器或挂代理，切全局代理也测试过，始终继续。
今天在lastpass论坛看到用户吐槽，其中有个用户提示删除“表单填充”字段，按提示删除后升级完成。
I noticed that I have secure notes that have duplicated many times. I deleted those notes, and noticed that they can never be completely erased - they keep coming back.
Then, I realized these notes are all "form fills", so I deleted them there.
I had a few "Form fills", but one of them had non-ASCII characters in the "Name" field. Renaming the non-ASCII form-fill immediately fixes the issue.
Previosly, before the form-fill was renamed, pressing "update" button brought LastPass in "updating" state forever.
换句话说：
1.进入你的vault。
2.点击左侧的“form fills”。
3.删除所有表格。
4.重新尝试升级
