yum update

my yum list updates show

 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

Error: Package mono-winfxcore-5.18.0.268-0.xamarin.3.epel7.x86_64 Requires mono-core 5.18.0.268

I fixed it by removing mono-winfaxcore package running yum update and then yum upgrade.

Same problem here:

Error: Package mono-winfxcore-5.18.0.268-0.xamarin.3.epel7.x86_64 Requires mono-core 5.18.0.268

Once again I’m having problems updating Nethserver below is the error I get when running yum update from the command line after running yum clean all any help with this matter would be greatly appreciated, [root@docu-server ~]# yum update Loaded plugins: changelog, fastestmirror, nethserver_events Loading mirror speeds from cached hostfile epel: reflector.westga.edu Resolving Dependencies –> Running transaction check —> Package certbot.noarch 0:1.0.0-1.el7 will be updated —> Package cer…

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

Edit: @mrmarkuz was a little bit faster than me

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

Set up Duplicati to back up your Neth Server

Ah, I must have previously installed it on this system and not remembered it. I’ll update. The open question, IMO, is how we’d make this comparable to the built-in backup/restore. I’m pretty sure, by backing up everything in /etc/backup-data.d/*.include, we get all the same data, but there are probably other steps needed to get the configuration in a usable way. Compared to the standard system, Duplicati lags in that it won’t handle SMB/NFS mounts. It can certainly back up to those location…

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

Better yet, add the Mono repo following the instructions for CentOS 7 here:
https://www.mono-project.com/download/stable/#download-lin-centos

The upgrade should then proceed without issue.
