Hi,

I get the following message when I try to run “apt update”.

Err:12 https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64  Packages
  File has unexpected size (1127072 != 1126689). Mirror sync in progress? [IP: 152.199.39.144 443]

I have tried “apt clean”, “rm -r /var/cache/apt /var/lib/apt/lists” and re-import the apt key, but still get the same error.
Is anything I should do to fix it?

I noticed that the cuda repository has been updated yesterday, so maybe the problem is on the repository side?

Please fix this, as its blocking work in the AV Division.
