Jiscmail say that the people who developed this feature have left so whatever the download bug is will not be able to be fixed.

I’ve tried various things, including converting the tgz from binary to base64 (so ascii). What seems to work best is zip format, so I have replaced the tgz file with a zip one which you can get via:

https://www.jiscmail.ac.uk/files/CCPNMR/ccpnmr2.4Updates20190301.zip

(e.g. using wget on Linux).

On Mac OSX this worked fine, so the file is downloaded correctly, with md5sum fd9504c4a4973d344983c318f54bafbe, and file size 547889. (Tested on one Mac.)

On Linux it is not downloading correctly, so it is coming out at file size 548016. But it seems to unzip ok, with some warnings. You can do the following to check if it’s going to cope ok (this just lists what is in the archive rather than actually unzipping it):

unzip -l ccpnmr2.4Updates20190301.zip

(Tested on two Linux boxes.)

There seem to be a bug in how Jiscmail deals with this file. So when you try and download you get a slightly larger file. On the Mac it seems to be random how much it adds, but it seems to unpack ok. On Linux it is a fixed amount extra that it adds but it does not unpack ok.

I’ve added an md5sum (in this case, e4db58600561e5560b1ba11837db0882) to the description of the file. From the above observation, this will never be the same as for what you can currently download.

I’ve emailed the Jiscmail help desk to see if they can explain what is going wrong (and why). For now, Mac users are probably ok to download but definitely not Linux users.

Hopefully this will be sorted. But it is always good practise to first check the md5 sum, and secondly to do “tar tvzf” first (which just lists what is in the tar file, rather than unpacking it) before extracting.

Hello,

For now the “update” mechanism in Analysis is broken because the server was shut down. As an alternative, for Analysis 2.4.2, I have put all the current updates (from the version of Analysis 2.4.2 available for download) at:


This tgz file will unpack into ccpnmr2.4/, which is located inside the top-level directory (which is normally called ccpnmr/ but might have been renamed by whomever installed Analysis on your computer). Thus you should place the tgz file inside the top-level directory before you unpack it. This is for Linux and OSX (not sure about Windows).
