I would advise to rename your model to GroupDetail, since not it will generate a lot of confusion since there are two models used: the Group from the django.contrib.auth.models, and the one you defined yourself.

Likely it is better to implement this as:

class GroupDetail(models.Model):
    group = models.OneToOneField(Group, on_delete=models.CASCADE, related_name='groups')
    # …

Then in the view, we can fetch the GroupDetails for a primary key with:

group = get_object_or_404(GroupDetail, pk=pk)

or if we want to work with the primary key of the referenced Group model, then it is:

group = get_object_or_404(GroupDetail, group__pk=pk)

This thus means that the view should look like:

def group_main(request, pk):
    context= {
        'groupdetail': get_object_or_404(GroupDetail, group__pk=pk)
    }
    return render(request,'group/grouptimeline.html',context)

Furthermore, you are rendering the GroupDetail object with variables that do not exist on the Group object. You should render these with:

<img src="{{ groupdetail.cover.url }}" alt="">
<!-- … -->
<h1> {{ groupdetail.group_name }} </h1>
