If you compile tar from scratch within the Docker container, then you do not see the error.
``` wget https://ftp.gnu.org/gnu/tar/tar-1.35.tar.gz tar -xzf tar-1.35.tar.gz ``` Ignore the errors from the tar process :-) ``` apt install build-essential libacl1-dev -y cd tar-1.35 FORCE_UNSAFE_CONFIGURE=1 ./configure --prefix=/usr make install ``` Now `tar -xf` works as expected. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to tar in Ubuntu. https://bugs.launchpad.net/bugs/2059734 Title: Tar fails to extract archives that include folders with certain permissions on armhf Status in tar package in Ubuntu: Confirmed Bug description: When running Ubuntu Noble in an arm32 Docker container, on certain hosts (Azure VM CI agents), tar fails to extract certain archives that include folders with specific permissions set. Here's a concise repro. The error occurs in when building the Dockerfile. I can only get this to work on Azure VMs, but can't find out why. ```Dockerfile FROM ubuntu.azurecr.io/ubuntu:noble # Create the problematic archive RUN mkdir /test \ && chmod 775 /test \ && cd /test \ && mkdir 775 \ && chmod 775 775 \ && touch 775/test.txt \ && chmod 644 775/test.txt \ && tar -czvf /test.tar.gz . # Extracting it gives an error RUN mkdir -p /test2 \ && tar -tzvf /test.tar.gz \ && tar -oxzf /test.tar.gz -C /test2 ``` What I expected to happen: The test.tar.gz archive should be successfully extracted to the /test2 directory. What happened instead: Tar throws the following error: ``` tar: ./775: Cannot change mode to rwxrwxr-x: Operation not permitted tar: Exiting with failure status due to previous errors ``` The Ubuntu container is running as root so there shouldn't be any permission errors. Since this is running in a container, I observed this happening on the following kernel: `Linux version 5.15.148.2-2.cm2 (root@CBL-Mariner) (gcc (GCC) 11.2.0, GNU ld (GNU Binutils) 2.37) #1 SMP Fri Feb 23 23:38:33 UTC 2024` As well as `Linux <hostname> 6.5.0-1017-azure #17~22.04.1-Ubuntu SMP Sat Mar 9 10:04:07 UTC 2024 aarch64 aarch64 aarch64 GNU/Linux` I was not able to reproduce it using Ubuntu 22.04 Jammy (ubuntu.azurecr.io/ubuntu:jammy), using the same kernel as above. Additionally I was not able to reproduce this on the kernel `Linux cb0507859b24 5.15.146.1-microsoft-standard-WSL2 #1 SMP Thu Jan 11 04:09:03 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux`, which is running on my work machine, using Docker qemu emulation for the arm32 image. Ubuntu version: Ubuntu Noble Numbat (development branch) 24.04 (from ubuntu.azurecr.io/ubuntu:noble) tar version: `1.35+dfsg-3` To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tar/+bug/2059734/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
