Public bug reported: An exception is randomly happening while ubiquity calling cachedpkg.mark_install() [1]. cachedpkg.mark_install() came from Cache class of python3-apt package.
It looks a timing issue while ubiquity calling cachedpkg.mark_install(), and a retry can workaround it. The reproduce rate is be about 1/15. Looks there're 2 things can be improved. 1. improve the fault tolerance of Ubiquity while it calling external library. 2. impvove the fault tolerance of python3-apt.
