Wired upgrade problem /usr/bin/python3

Hi I’m on NethServer release 7.6.1810
if I do a
yum clean all
yum update

my yum list updates show

[root@nethserver1 ~]# yum list updates

Updated Packages

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

I have python 3.6 installed

[root@nethserver1 ~]# ls -lai /usr/bin/python
123 lrwxrwxrwx 1 root root 7 Sep 11  2019 /usr/bin/python -> python2
[root@nethserver1 ~]# ls -lai /usr/bin/python3

[root@nethserver1 ~]#

Same problem here:

Try to uninstall mono-winfaxcore. After this update should work.

Edit: @mrmarkuz was a little bit faster than me :joy:


I need a working mono instance because I use mono and duplicati if I remove mono duplicati gone.

Better yet, add the Mono repo following the instructions for CentOS 7 here:

The upgrade should then proceed without issue.
