Hi, I’m trying to perform standalone mender update from a USB Pendrive. I have put the \* .mender artifact inside the Pendrive and run the below command: `mender -debug -install /run/media/sda1/*.mender` But, I’m getting the below error: `ERRO[0000] mkdir /var/lib/mender: file exists module=main` Could you please let me know what this error means? ---

Which version of the Mender client? What does `ls -alh /var/lib` give you? ---

Why is the client version dirty? For this reason it is hard to comment. Looking at the code, > I can not determinate why it would fail here. Do you have the correct permissions? Multiple clients running? ---

Thank you @mirzak for your reply. I’m using `sources/meta-mender/meta-mender-core/recipes-mender/mender/mender_2.0.0.bb` with `SRC_URI = "git://github.com/mendersoftware/mender;protocol=https;branch=2.0.x"`. Even I don’t know why the `dirty` is coming at the end of the 2.0.0 version! Is there any reason for it? Regarding the permission, I’m using a read-only file system and only one client is running on the target platform. Whether it will work on a read-only file system? 🤔 ---

Does the `/data/mender` directory exist? ---

> [@ajithpv](#): > > Regarding the permission, I’m using a read-only file system I do not think that this should matter, because `/data` should be a mount point to a separate partition that should not be `read-only`. Or this not the case? ---

My bad, somehow, the `/data/mender` directory didn’t populated on the build which I used. This is the reason for the mentioned error 🤐
