Title: /tmp sticky bit do not permit writing fifo file inside Status in linux package in Ubuntu: Invalid Bug description: Trying to write into a fifo pipe inside /tmp (echo "hello" > /tmp/fifo) whit normal permissions (drwxrwxrwt, sticky bit) and the fifo with prw-rw-rw- permissions and with "other" user than user and group owner ends in this error: bash: /tmp/fifo: Permission denied. It occurs since upgrading to Ubuntu 20.04, in 19.04 it worked as expected. When I remove the sticky bit (drwxrwxrwx) from tmp it works normally. I think it is a misbehaviour, with sticky bit you cannot rename or remove files inside that folder, but could be able to write into them.
