We test and use LibreELEC with a clean setup, and installing skins is not an issue.
So perhaps in your case something else is getting is the way.
Get us a kodi.log file to see your LE box' internals.
Get a kodi log file and there will written what is going on.
We have no crystal ball here.
You haven't even bothered to mention which hardware this is about.
Please get us a log file as requested.
No Kodi debug log = No problem.
I installed on 2 different Intel NUC's (1st generation and 7th generation) and the issue is the same. So hardware does not matter.
"No Kodi debug log = No problem." 
Yeah. yeah I know the drill.
I will get the log file.

Either install a real clean set up of LibreELEC, or walk away.
I think you have some DNS problems and your names are not resolved to ip address. This is the indication:
QuoteURLError: <urlopen error [Errno -3] Temporary failure in name resolution>

As a last reserve you could add this into autostart.sh file

I asked nicely for help, so your "walk away" was not necessary.
So the next time you had a bad day and can't reply nicely to a question I suggest you "walk away".

Thanks Peter. It turns out to be the DNS on my Fortigate which was blocking some requests.

You seem to have the wrong view on the situation. You are visiting OUR forum, so it is OUR rules on OUR software, especially the part on the piracy policy section. It's a zero-tolerance policy in case you hadn't noticed.
Actually, I don't have a bad day. If I would have a bad day, all your posts and your LibreELEC forum membership would have been wiped off this forum a long time already. So don't piss off the guy with the nuke button by telling him what to do or not to do. If you have a problem with authority, there are online help groups you can visit.
