Description Doran Barton 2019-05-08 03:04:19 UTC 
Description of problem:

When trying to build, or even initialize a mock root for epel-[67]-x86_64, package installation fails either because /usr/libexec/urlgrabber-ext-down does not exist or because of a python error in urlgrabber-ext-down. 

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

python2-urlgrabber-4.0.0-1.fc30.noarch
python3-urlgrabber-4.0.0-1.fc30.noarch
mock-1.4.15-1.fc30.noarch
yum-3.4.3-521.fc30.noarch
dnf-4.2.2-2.fc30.noarch
systemd-241-8.git9ef65cb.fc30.x86_64

How reproducible:

It's pretty consistent.

Steps to Reproduce:
1. mock -r epel-6-x86_64 init
2. If python3-urlgrabber is installed, a python error causes install to fail
3. If python4-urlgrabber is not installed, install fails because /usr/libexec/urlgrabber-ext-down does not exist

Actual results:

Traceback (most recent call last):
  File "/usr/libexec/urlgrabber-ext-down", line 75, in <module>
    main()
  File "/usr/libexec/urlgrabber-ext-down", line 52, in main
    for k in line.split(' '):
TypeError: a bytes-like object is required, not 'str


Expected results:

Comment 1 Doran Barton 2019-05-08 03:06:17 UTC 
This is essentially the same as bug #1688173 (which is rawhide.)
Comment 2 Miroslav Suchý 2019-05-09 10:54:56 UTC 
This traceback is clearly python3-urlgrabber bug (soft deps of mock).

The reproducer is:
dnf install mock python3-urlgrabber
mock -r epel-6-x86_64 init

Comment 7 Pavel Raiskup 2019-05-13 12:57:05 UTC 
For those who can do it, it's probably much better to remove yum
package from the system, and keep only `dnf-yum` package installed
on F30;  mock then uses `dnf-yum` which doesn't use urlgrabber
at all, more info here:
