Tree Hash Mismatch while installing JLD on Julia 1.6.1

[mkolar]

I’ve just downloaded Julia Version 1.6.1 (2021-04-23) on a cluster and run into a Tree Hash Mismatch when installing JLD package.

I’ve looked at the discussion here:

Problems with environment - Tree Hash Mismatch!

I’d start from doing what the message suggests

but starting Julia with

LD_LIBRARY_PATH="" julia

did not help.

The file system is nfs.

I would appreciate any suggestions on how to resolve this.

See

Artifact hash mismatch when installing libpng (Julia 1.6.1)

If @HerAdri was previously successfully using the pkg server to acquire all artifacts and that isn’t working now for some reason, there are a few reasons this could happen: The default Pkg behavior changed The user changed JULIA_PKG_SERVER setting This is a new artifact that the pkg servers don’t have yet The first thing shouldn’t have happened in a point release. The second presumably didn’t happen or @HerAdri would have mentioned it. That leaves the third thing, which is likely because ther…

I think it is related.

I don’t think so, this is a mismatch of the git tree sha1, but the tarball hash was apparently ok, otherwise it’d have failed before

[mkolar]

Thank you for your replies.

Is there anything on my side that I can do to resolve the issue?

I do not have this problem on my local machine and not quite sure how to proceed.

[giordano]

Quite frankly I have no idea what to do. I thought that in Julia v1.6 the git tree sha check was non fatal. It doesn’t seem to be the case though. I’d suggest you to open an issue in Pkg (yet another about this problem, but maybe at some point someone will take the time to fix it)

The following workaround suggested by a data scientist managing the cluster worked for me.

First set

export JULIA_DEPOT_PATH="/tmp/.julia"

and install the desired packages. Then move the installation directory to my home folder and reset the environment variable. This apparently works as the /tmp folder is not on an NFS partition.
