I am using JoplinPortable.exe from a USB stick that travels to different computers. On 3/3 computers, I am unable to update to the latest version of a plug-in.
Do the /tmp and /plugins directories exists on the USB key? Could it be some permission issue? For example, you install the plugin on computer 1, so the folder gets the permission setup on that computer. Then when you try from computer 2, the permissions are different.
Sorry, I meant to write that I reset the READONLY attribute flag to off, meaning that writing is enabled on those USB directories. A restart of the app doesn't seem to help.
@markrenier it does not appear to be your setup or flash drive.
I just tried to update a plugin (using 2.5.1) to see if I could duplicate the error and I can.
Apparently EISDIR means:
... that the target of the operation is a directory in reality but that the expected filetype of the target is something other than a directory.
Also I notice that the second path shown does not look like a valid path for Windows (forward slashes)
EDIT:
Could not install plugin Error EISDIR illegal operation on a directory
Just adding these keywords as so far the error has only been posted as an image. If anyone searches for this error this post should now show up. (Whether they bother to search the forum is another matter!!)
