trouble-free
Proceeding without problems, difficulties, or complications. Can be used as an adjective or adverb.
Die Installation der neuen Software verlief völlig problemlos.
The installation of the new software went completely trouble-free.
The word is made up of 'Problem' (problem) and the ending '-los' (-less). The ending '-los' means 'ohne' (without) and can be attached to many nouns to form an adjective (e.g., 'arbeitslos' = unemployed, 'harmlos' = harmless).
Er kaufte ein Ticket für eine sorgenlose Reise in die Sonne.
He bought a ticket for a carefree trip to the sun.
'Problemlos' (trouble-free/without problems) can be used as an adjective before a noun or as an adverb to describe a verb. As an adjective, it is declined; as an adverb, it remains unchanged.
Das war eine problemlose Reparatur.
That was a trouble-free repair.
As an adverb, 'problemlos' (without problems/smoothly) is often combined with verbs such as 'funktionieren' (to function/work), 'verlaufen' (to proceed), 'klappen' (to work out), or 'möglich sein' (to be possible).
