Description Terje Røsten 2017-07-03 17:39:25 UTC
Description of problem:

dnf stops with:

Totalt                                           10 MB/s | 611 MB     00:59
The downloaded packages were saved in cache until the next successful transaction.
You can remove cached packages by executing 'dnf clean packages'.

Version-Release number of selected component (if applicable):

$ rpm -q dnf rpm
dnf-2.5.1-1.fc26.noarch
rpm-4.13.0.1-4.fc26.x86_64


How reproducible:

Might be related to non utf-8 locale:

$ locale
LANG=nb_NO.iso88591
LC_CTYPE="nb_NO.iso88591"
LC_NUMERIC="nb_NO.iso88591"
LC_TIME="nb_NO.iso88591"
LC_COLLATE="nb_NO.iso88591"
LC_MONETARY="nb_NO.iso88591"
LC_MESSAGES="nb_NO.iso88591"
LC_PAPER="nb_NO.iso88591"
LC_NAME="nb_NO.iso88591"
LC_ADDRESS="nb_NO.iso88591"
LC_TELEPHONE="nb_NO.iso88591"
LC_MEASUREMENT="nb_NO.iso88591"
LC_IDENTIFICATION="nb_NO.iso88591"
LC_ALL=


Steps to Reproduce:
1. set locale as above
2. run dnf update

I recommend using UTF-8 (except some special cases. Eg. small embeded systems).
