I'm using an instance of Amazon EC2, Redhat.
Since I updated yum last time, it doesn't work any more, always get error messages of 404 not found, for example:
failure: repodata/repomd.xml from rhui-REGION-rhel-server-releases: [Errno 256] No more mirrors to try.
https://rhui2-cds01.us-east-2.aws.ce.redhat.com/pulp/repos//content/dist/rhel/rhui/server/7/%24releasever/x86_64/os/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found

Anyone knows the solution?
According to redhat https://access.redhat.com/articles/1320623
Typical Cause This issue generally occurs if client system is able to
communicate with given server but could not find or access the
requested package on the server.
Resolution This issue can occur due to corruption of local client
cache, try to clear cache on client system:
Try
rm -fr /var/cache/yum/*
yum clean all
then
yum update

I just installed Anaconda and now I'm trying to install pytorch via conda install pytorch torchvision cudatoolkit=10.2 -c pytorch. But I'm getting the error message
Collecting package metadata (current_repodata.json): failed
CondaHTTPError: HTTP 503 SERVICE UNAVAILABLE: BACK-END SERVER IS AT CAPACITY for url <https://conda.anaconda.org/pytorch/win-64/current_repodata.json>

A remote server error occurred when trying to retrieve this URL.
A 500-type error (e.g. 500, 501, 502, 503, etc.) indicates the server failed to
fulfill a valid request. The problem may be spurious, and will resolve itself if you
try your request again. If the problem persists, consider notifying the maintainer
of the remote server.
How can I resolve this and install pytorch? Is anaconda.org just down temporarily?
The answer to your problem is in your question itself . The last paragraph says that :
A 500-type error (e.g. 500, 501, 502, 503, etc.) indicates the server failed to
fulfill a valid request. The problem may be spurious, and will resolve itself if you
try your request again. If the problem persists, consider notifying the maintainer
of the remote server.
This would mean that you would have to try again later . This generally happens when the official websites are down and this has happened earlier as well . So you just have to wait it out.
Getting this message when trying to install wget in RHEL EC2 instance. How to resolve this?
Error: Failed to download metadata for repo 'rhui-client-config-server-8': Cannot prepare internal mirrorlist: Curl error (28): Timeout was reached for https://rhui3.ap-south-1.aws.ce.redhat.com/pulp/mirror/protected/rhui-client-config/rhel/server/8/x86_64/os [Connection timed out after 30000 milliseconds]
If you set up SSH for the EC2 instance, try and SSH into the machine, and try
curl -I https://www.google.com
and if it times out, you perhaps can't connect to the internet.
You need to check if the relevant Security Group has an outbound rule allowing connections to the internet:
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-security-groups.html?icmpid=docs_ec2_console#security-group-rules
There are a few useful hints in https://access.redhat.com/discussions/4656371 as well, if the issue is related to your subscription.
I've tried
conda install -c conda-forge pyperclip
and get the following error:
Solving environment: failed

HTTP errors are often intermittent, and a simple retry will get you on your way.
If your current network has https://www.anaconda.com blocked, please file

I've also try to download pyperclip-1.7.0.tar.gz, unzip it (the folder is pyperclip-1.7.0) and copy it to multiple folders (e.g. ...\Continuum\anaconda3\Scripts and ...\Continuum\anaconda3\Lib)
but when I try to import it, I get a "ModuleNotFoundError: No module named 'pyperclip'" message
pip install pyperclip
worked from the Anaconda prompt (I was using CMD)
I've gone through almost everything related to installing sbt on Window on stackoverflow (there are quite a few people having the same problem with me). However, the answer seems unclear/unreproducible on my machine.
Here is what I did:
Download sbt-0.13.13 on this site
Install it successfully and set the PATH
Try sbt version to see if it is installed successfully. Error
returned (as at the end of this post)
A few things we should know:
I already have JDK
I don't use Proxy on my computer (tested with netsh winhttp show
proxy)
Someone said it is because sbt doesn't support ASCII character - but
the solution wasn't clear

You could try to configure the use of IPV4 (not IPV6), as described in the accepted answer for this question:
Error while importing sbt project , Server Access error, unresolved dependencies
setx _JAVA_OPTIONS -Djava.net.preferIPv4Stack=true
I was struggling with the same for a week. The only thing, that helped, was to uninstall sbt from the default location (c:\Program Files(x86)\sbt) and reinstall it to some location without spaces (I've installed it to d:\sbt).
Did you try taking a look in your sbt repositories file (likely to be c:\users\.sbt\repositories, and specifying http:// instead of https:// ?
I am using chef dk version 12 and i have done basic setup and uploaded many cookbooks , currently i am using remote_directory in my default.rb
What i have observed is whenever there are too many files /hierarchy in the directory the upload fails with the below exception :-
ERROR: SSL Validation failure connecting to host: xyz.com - SSL_write: cert already in hash table
ERROR: Could not establish a secure connection to the server.
Use `knife ssl check` to troubleshoot your SSL configuration.
If your Chef Server uses a self-signed certificate, you can use
`knife ssl fetch` to make knife trust the server's certificates.
Original Exception: OpenSSL::SSL::SSLError: SSL_write: cert already in hash table
As mentioned earlier connection to server isnt a problem it happens only when there are too many files/the hierarchy is more .
Can you please suggest what i can do? I have tried searching online for solutions but failed to get a solution
I have checked the question here but it doesnt solve my problem
Chef uses embedded ruby and openssl for people not working with chef
Some updates on suggestion of tensibai,
The exceptions have changed since adding the option of --concurrency 1 ,
Initially i had received,
INFO: HTTP Request Returned 403 Forbidden:ERROR: Failed to upload filepath\file (7a81e65b51f0d514ec645da49de6417d) to example.com:443/bookshelf/… 3088476d373416dfbaf187590b5d5687210a75&Expires=1435139052&Signature=SP/70MZP4C2UdUd9%2B5Ct1jEV1EQ%3D : 403 "Forbidden" <?xml version="1.0" encoding="UTF-8"?><Error><Code>AccessDenied</Code><Message>Access Denied</Message>
Then yesterday it has changed to
INFO: HTTP Request Returned 413 Request Entity Too Large: error
ERROR: Request Entity Too Large
Response: JSON must be no more than 1000000 bytes.
Should i decrease the number of files or is there any other option?
Knife --version results in Chef: 12.3.0
Should i decrease the number of files or is there any other option?
Ususally the files inside a cookbook are not intended to be too large and too numerous, if you got a lot of files to ditribute it's a sign you should change the way you distribute thoose files.
One option could be to make a tarball, but this makes harder to manage the deleted files.
Another option if you're on an internal chef-server is to follow the advice here and change the client_max_body_size 2M; value for nginx but I can't guarantee it will work.
I had same error and i ran chef-server-ctl reconfigure on chef server then tried uploading cookbook again and all started working fine again
