## Mega thread for reporting metdata issues with the CUDA repositories
Is the… CDN stale? Have you seen something like:
```shell
E: Failed to fetch *.deb Hash Sum mismatch
Hashes of expected file:
- SHA512:$sha512, SHA256:$sha256, SHA1:$sha1 [weak], MD5Sum:$md5 [weak], Filesize:$bytes [weak]
Hashes of received file:
- SHA512:$sha512, SHA256:$sha256, SHA1:$sha1 [weak], MD5Sum:$md5 [weak], Filesize:$bytes [weak]
Last modification reported: $(date -R --utc)
```
or
```shell
*.rpm: Downloading successful, but checksum doesn't match.
Calculated: $sha256(sha256)
Expected: $sha256(sha256)
```
### Please provide the following information in your comment:
1. The error message and the last command(s) run.
2. When was the `Release` (Debian) or `repomd.xml` (RPM) file last modified ?
```shell
$ curl -I https://developer.download.nvidia.com/compute/cuda/repos/$distro/$arch/Release
$ curl -I https://developer.download.nvidia.com/compute/cuda/repos/$distro/$arch/repodata/repomd.xml
```
3. The Linux distro and architecture. If cross-compiling or containerized, please mention that.
```shell
$ cat /etc/os-release
$ uname -a
```
4. Which NVIDIA repositories do you have enabled ?
Do your `.list` / `.repo` files contain URLs using HTTP (port 80) or HTTPS (port 443) ?
5. Which geographic region is the machine located in ?
6. Which CDN edge node are you hitting ?
7. Any other relevant environmental conditions (i.e. a specific Docker container image) ?
Hi @erikwijmans ubuntu1604/x86_64 and fedora32/x86_64 repos, the rest will follow in a bit.
The new GPG keys for the CUDA repository
Please remove the old 7fa2af80 key
Debian-based distros:sudo apt-key del 7fa2af80
RPM-based distros:sudo rpm --erase gpg-pubkey-7fa2af80*
And enroll the new signing key (a cuda-keyring package is also provided)
sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/3bf863cc.pub
RPM-based distros: please update .repo with package manager specific instructions (see blog post)
