What's not working

I got cp: cannot create regular file '/var/tmp/pamac/dbs/sync/pamac_aur.db': Permission denied when using pamac update. pamac_aur.db file was existing in the folder above.

I tried to fix privs: sudo chown -R $(whoami):$(whoami) /var/tmp/pamac/ and rerun pamac update. Now my pamac_aur.db got removed from the directory:

    ~  ls -al /var/tmp/pamac/dbs/sync/                                                                                                                                                                    2 ✘

Running pamac update again will bring the same permission denied error as above. It will not create a new database.

I tried to run sudo pamac update which refreshes aur without error. However, it doesn't create a new pamac_aur.db in the sync directory. Instead I found out, another one was created in the main folder:

    ~  ls -al /var/tmp/pamac/                                                                                                                                                                     1 ✘  45s 

How can I fix this?
