Upgrade to fedora 25 fails, consistently

Dear all,

as I could not find an answer to my previous question (excessive time for execution of a trivial executable) I thought that I should - before I try any other tricks - upgrade my fedora 24 --> 25.

Seems that this was not such a good idea. Here is what happened: I chose the procedure described in

The first two commands were successful

1) sudo dnf upgrade --refresh

2) sudo dnf install dnf-plugin-system-upgrade

but then, when trying to execute

sudo dnf system-upgrade download --releasever=25 --allowerasing

I got the this message:

Curl error(18): Transferred a partial file for [transfer closed with 1176 bytes remaining to read]

There is enough space on my disk, and I got this message, with the same number of missing bytes at three attempts.

Obviously I would like to understand how I can do my upgrade, but let me first ask two "meta" questions:

  1. Is the fedora 25 really ready or is it premature to try the upgrade?

  2. If yes, is the above mentioned web page a trustworthy description of the procedure?

Thanks in advance, BerndP

This isn't strictly Fedora 25 or even dnf upgrade related, the error is with curl which is what's doing the actual work to download the packages. I suspect it's a confused mirror. So the question is how to get dnf to use a different mirror. You could try editing /etc/dnf/dnf.conf to add 'fastestmirror=true' and then rerun the last dnf command.

Thank you very much for this first hint. So I tried, and indeed after 3 failures before with 1176 bytes still to be read, I am now down to 1101. (at 1st + 2nd try). Slight improvement, but not enough. Interesting, the system this time "promised" to look for faster mirrors. But is fastest also the best?

So, unfortunately, I still don't seem to be able to upgrade. Any other "tricks"?

Just to put you in context: The download involves about 5.3 Gbytes, my monthly budget is only 40Gb, I have to wait for the night when downloads are "free" ... especially at the beginning of the month.

.. one more question in this context: Is there any systematic way, in which I can go through one specific mirror at a time, i.e. whenever a mirror fails, go to the next one? I am willing to do this by hand, as I really think it is a proper strategy to work with the current version of a sytem, before trying any "tricks" on the "older" version.

In the end, if upgrade of fedora is not possible, I see only one desperate way out, i.e. try another distribution of Linux. Whether this would then solve my problem, I do not know, but remaining with fedora without upgrade doesn't do it, it seems.

Dear all, just to keep you uptodate: I found some advice from a (real) person doing fedora installments and giving courses.

He told me that there is no interest in upgrading f24->25 as long as one has not a particular option in mind (which is only offered by f25). Contrary to what I thought, no improvement as far as "normal" executables can be expected, and therefore one should abstain from the upgrade (which seems to be not possible anyhow).

In this context: In the meantime the author of praat, which was performing far too slow on my fedora 24, found a kind of bug. Strangely enough, this bug manifested itself only on fedora, not on other linux distributions.
