Thank you

This is after upgrade by your steps. but still in 21.04 , not 21.10.

        100 /var/lib/dpkg/status

Expecting:
Arabic work fine in all Ubuntu systems , I readd like this problem every 3 years (since Ubuntu 6.??) . like this problem fixed many times & return in other release as new bug !.

Also, Some Arabic fonts are not working in all ubuntu systems but working in MS Windows.
And most readd this bug in every release . It was fixed in 7.10? & 10.10? .

Happens:
Every new release ignored Arabic local settings & apps.
