sagemath-upstream-binary 7.2: install fails because of size mismatch after download

[Giuseppe Scollo]

The command, issued after sudo apt-get update, and the subsequent events are copied below.
It seems to me that a 629 MB download is expected, whereas an actual 216 MB takes place, is this the cause of the problem? If so, how to fix it?
My system is an Ubuntu 14.04, I removed the previous sage installation (v. 7.1), so this was a fresh installation attempt. Thanks a lot, in advance.

Thanks for reporting. I am also getting this from the stable PPA, and will investigate. I first thought it was our local cache hosting a corrupted copy. It is already getting a 600M copy:

I've also started a download of the deb directly here: https://launchpad.net/~aims/+archive/ubuntu/sagemath/+files/sagemath-upstream-binary_7.2~aimsppa1_amd64.deb

and firefox thinks that is 600M in size, and the download has surpassed 207M.

The deb package was copied (using a launchpad feature) from the development PPA at ppa:aims/sagemath-dev, so a workaround might be to briefly use the dev PPA if your need is urgent. Note that the files are listed as the same size:
https://launchpad.net/~aims/+archive/ubuntu/sagemath-dev/+packages
https://launchpad.net/~aims/+archive/ubuntu/sagemath/+packages

However, I will retry a copy, if launchpad allows, else I will have to delete first.

Regards,

Jan

Hi

This is a strange one. debmirror repeatedly cached a bad 200M copy. Firefox downloaded the correct 600M copy and I could scp it into the cache and now the campus laptops can update again.

I am going to delete the package on launchpad, wait 1 hour, confirm it is gone, and copy it in again. Would be great if you could test in 2 hours and let me know.

Regards,

Jan

Hi

Launchpad administrator tells me there was an issue last week like this which affected rare files (only 3 they know of). But that I would have to delete, wait at least 6 hours, and then copy back. I am deleting all 7.2 now.

Regards,

Jan

I have copied back 7.2 to Trusty, Wily, Vivid, and Xenial in the PPA. Please test and let me know.

I have just requested a copy on launchpad. Should be ready in an hour.

Note the difference though: http://files.sagemath.org/linux/64bit/index.html has binaries from the sage buildfarm built on 14.04, 14.04, 14.10, 16.04 with the toolchain from that release. Yakkety is not yet included.

Only 14.04 is rebuilt into a PPA, and on launchpad the 14.04 binary/deb is copied forward to 15.04, 15.10, 16.04 (and now 16.10). So far no problems, but if you run into problems you may want to download and unpack the 16.04 binary which is much closer to the toolchain version of 16.10 than the 14.04 binary.

[Henri Girard]

thanks...
Which is better for me : sagemanifolds works fine after compilation.
I am on version Xenial but as soon as I can get the 16.10 version I will try it.
Anyway I can downgrade to 16.04
Best regards

Henri
