Hi Igor,
I’m facing the same issue. As usual it seems specific to some mirrors. AFAICT Nvidia uses Akamai’s CDN and the issue seems to be specific to some mirrors. You’re having issues with 23.62.46.152 and I’m having issues with 23.48.165.11 both of which are located in the UK. I suggest you switch to a different ip address like so:
echo "95.100.95.145 repo.download.nvidia.com" >> /etc/hosts
You can identify alternative ip addresses by running dig repo.download.nvidia.com from different locations/countries.
Hope this helps.
