Container of chopped-up garb and assorted gubbins, primarily (6)
I believe the answer is:
ragbag
'container' is the definition.
(ragbag is a kind of container)
'chopped-up garb and assorted gubbins primarily' is the wordplay.
'chopped up' indicates anagramming the letters.
'and' means one lot of letters go next to another.
'primarily' indicates taking the first letters.
The first letters of 'assorted gubbins' is 'ag'.
'garb' anagrammed gives 'ragb'.
'ragb'+'ag'='RAGBAG'
'of' is the link.
(Other definitions for ragbag that I've seen before include "Motley collection" , "Miscellany" , "Miscellaneous collection - of fabric scraps?" , "salad" , "Random collection" .)
