What is the best way to fix a sticky gearshift in an Audi 80?

I've noticed that my gearshift in my Audi 80 is starting to stick and it's becoming difficult to shift gears. I've tried lubricating it but it doesn't seem to be helping much. Any tips or tricks for fixing this issue?

You may want to check the linkage under the gearshift for any debris, as this can cause it to stick. Use a small brush or compressed air to clear it out. Also, try adjusting the linkage if necessary.
