Oracle: Central inventory is not locked

Today while installing Oracle 12c R1, I have got an error that says “Central inventory is not locked”

Solution: It failed to acquire a lock on Inventory.

$ cat /etc/oraInst.loc
inventory_loc=/u01/app/12.1.0.2/grid/oraInventory
inst_group=oinstall

Then, went to¬†/u01/app/12.1.0.2/grid/oraInventory directory and removed “locks” directory. This fixed the issue.
