Error in astra linux, no access to FIFO file?

Question

linux

Friends began to experience the miracle of Russian development, tell me how to overcome this error, there is no access to the FIFO file /tmp/fly-wm-:0. Check your permissions to create-record it. If they are not enough, ask the admin to delete this file and restart the session.

Answer 1

The only thing I can think of using FIFO for is the exchange of data between two different processes, hence the question "With what rights do they run? Maybe from under different users."
Next, if the file exists, check its stat , attr and lsattr command attributes .
Check with what options the directory is mounted, maybe the nouser flag is set
