Error "no free space in /var/cache/apt/archives" in singularity container, but disk not full

Asked 2022-Apr-14 at 10:20

I'm trying to reproduce results of an older research paper and need tp run a singularity container with nvidia CUDA 9.0 and torch 1.2.0. Locally I have Ubuntu 20.04 as VM where I run singularity build. I follow the guide to installing older CUDA versions. This is the recipe file

As described in overview section of singularity build documentation

build can produce containers in two different formats that can be specified as follows.

compressed read-only Singularity Image File (SIF) format suitable for production (default)

writable (ch)root directory called a sandbox for interactive development (--sandbox option)

Adding --sandbox should make the system files writable which should resolve your issue.

Ideally, I'd suggest adding any apt-get install commands to the %post section in your recipe file.

The disk sdb is 1,000 GB, but the file system placed on that disk is 98 GB. The simplest solution is to copy the data from that disk and reformat it with a larger file system.

First of all, don't name your custom object type Object. Type Object is built in type for Object value. It may confuse people. I'm not sure whether you want to update existing Object type or you want just to create some custom type, it is important for interfaces because of declaration merging.

consider this example:

I am working on yocto,dunfell, am trying to build .hddimg image for a genericx86-64 machine. I inherit image-live, add hhdimg to IMAGE_FSTYPES and everything works fine with iso, wic and ... But when I add hddimg I get this error:

...

ANSWER

Answered 2022-Jan-19 at 12:28

Your rootfs for test-image is larger than 4GB, which is the maximum filesystem size for FAT partitions (the default used by the .hddimg image type).

The error already contains two solutions:

Reduce the image size, by removing packages
Use the wic format (vmdk and vdi are for virtual machine engines)

To use the wic format, simply add wic to IMAGE_FSTYPES and Yocto will build a .wic image and place it in the deploy/images directory. You can flash this to your disk using dd or bmaptool, and boot it.

These images are built from a template specified by WKS_FILE, which defaults to genericx86.wks.in for the the genericx86-64 machine. This default template creates a partition table and installs an EFI bootloader (Grub).

If you'd like to manually generate the wic images or modify the templates, check out the documentation for Creating Partitioned Images Using Wic.

Once you've successfully opened the file, you can use FileDevicePath(handle[i], L"MY_FOLDER\\myB.efi") (which you should have if using EDK2 or GNU-EFI) to get an EFI_DEVICE_PATH which points to the file. Then you can load the image with something like as follows

QUESTION

UEFI UDP Receive token

Asked 2021-Dec-20 at 14:30

Sample code such as that provided by MiSimon in Send TCP or UDP packets from efi application shows how to send and receive a single packet. I have successfully been able to send multiple packets, but I'm having difficulties on the receive side.

The documentation for the UEFI UDP Protocol EFI_UDP4_PROTOCOL.Receive() function says that it

Places an asynchronous receive request into the receiving queue.

Based on the EDK2 source code, one might infer this does something like NetMapInsertTail() placing the new token on the RxTokens list. According to the same source, it would appear that when a datagram is delivered, this token is removed with NetMapRemoveHead(). However, empirically after I successfully receive one packet, return from the callback and signal the RecycleSignal, my next call to Receive() fails with EFI_ACCESS_DENIED, described in this context as:

A receive completion token with the same Token.Event was already in the receive queue.

The interface does not provide any API to determine what is in the "receive queue", so it's not easy to investigate whether the 'remove' operation simply isn't doing what I think it is, or whether it's getting requeued, etc.

So the crux of my question is: how do I arrange to receive multiple datagrams from the same UDP port?

Is the token on the receive queue something that should be reusable many times without multiple calls to Receive()? (If so, what has to be done to prepare it for reuse?)
Or is it something that needs to be created anew for each incoming packet? (And if so, then when and how are they freed?)

...

ANSWER

Answered 2021-Dec-20 at 14:30

The event in the token is only called once, the specification says (Spec 2.9, Chapter 30.1.2 Receive):

"Providing a proper notification function and context for the event will enable the user to receive the notification and receiving status. That notification function is guaranteed to not be re-entered."

You need to allocate a new event for every token. If you want to listen for more then one datagram at the same time you can use unique contexts for each event but the same notify function.

For each token you have to:

Create event and token -> call receive -> handle datagram or error -> signal the recycle event -> free the token event
