I did "nix-store --delete" on the store path of haskell-clientsession. as Peter suggested in a private mail then. But my problem is still: I ran for n in $(find /nix/store -name "*haskell-clientsession*" -maxdepth 1); do nix-store --delete $n; done but it still tells me: finding garbage collector roots... error: cannot delete path ‘/nix/store/pqj35vwax89ljdhcca02a330ii4zzhiw-haskell-clientsession-0.9.1.1.drv’ since it is still alive 0 store paths deleted, 0.00 MiB freed Can you tell how to fix this? -- Mit freundlichen Grüßen, Kind regards, Matthias Beyer Proudly sent with mutt.
