Dear Maintainer,

When there are packages ugradable, select them to upgrade,
and press 'g' to enter preview mode, then select any one
of the packages, you will see
  Internal error: bad format string code ' '
in the bottom window.
Are there some detailed package information show there previously?

Thanks
