You better check with Qatar embassy in Uganda for your visa related issue. Even if your visa is positive in Qatar and arrive here directly , then no issue but if you travel through UAE then it is 100% you will be in jail without any question.

Not only for moving to Qatar, even if you travel to pak through UAE , you will be caught so be careful .
Also advise you to check with UAE embassy in Uganda to clear your issue and make free to fly there itself.
