Tested and verified. Note that there is no original TEST CASE, but the original issue is clearly reproducible. Used the following TEST CASE to verify:
1. Installed 22.04 in WSL2 (for performance reasons until everything is updated) 2. sudo apt update && sudo apt upgrade -y 3. Installed my normal working environment (Fish shell, httpie, exa, etc. etc.) 4. Downloaded https://gnu.askapache.com/gzip/gzip-1.12.tar.gz (as a test gzip'd file) 5. tar xvzf gzip-1.12.tar.gz: Succeeded (this is still WSL2) 6. Removed resulting directory 7. Exited Ubuntu/WSL 8. Converted to WSL1 with "wsl --set-version Ubuntu-22.04 1" 9. Restarted Ubuntu-22.04 under WSL1 10. tar xvzf gzip-1.12.tar.gz: Failed with "/usr/bin/gzip: 1: ELF: not found" 11. gunzip gzip-1.12.tar.gz: Failed with "/usr/bin/gunzip: 57: exec: gzip: Exec format error" 12. sudo apt update && sudo apt upgrade -y: No updates 13. Added jammy-proposed to sources (as root) with: cat <<EOF >/etc/apt/sources.list.d/ubuntu-$(lsb_release -cs)-proposed.list # Enable Ubuntu proposed archive deb http://archive.ubuntu.com/ubuntu/ $(lsb_release -cs)-proposed restricted main multiverse universe EOF 14. Set selective-install of gzip via (as root): cat <<EOF >/etc/apt/preferences.d/proposed-updates # Configure apt to allow selective installs of packages from proposed Package: * Pin: release a=$(lsb_release -cs)-proposed Pin-Priority: 400 EOF 15. "sudo apt update" 16. Verified selective install is set via "sudo apt upgrade -s" 17. sudo apt install gzip/jammy-proposed 18. tar tvzf gzip-1.4.tar.gz: Succeeded 19. gunzip gzip-1.4.tar.gz: Succeeded 20. tar tvf gzip-1.4.tar: Succeeded (confirms successful gunzip) 21. tar xvf gzip-1.4.tar: Succeeded (Confirms successful gunzip) 22. gzip ~/.profile: Succeeded 23. gunzip ~/.profile.gz: Succeeded apt info gzip Package: gzip Version: 1.10-4ubuntu4.1 ** Tags removed: jammy verification-needed-jammy ** Tags added: verification-done-jammy -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gzip in Ubuntu. https://bugs.launchpad.net/bugs/1966849 Title: gzip exec format error under WSL1 Status in gzip: New Status in gzip package in Ubuntu: Fix Released Status in gzip source package in Jammy: Fix Committed Status in gzip source package in Kinetic: Fix Released Bug description: [Impact] * Optimization features included in jammy cause atypical alignment of LOAD ELF sections. This in turn causes failure to execute binaries on WSL1. Upstream have since integrated the optimization features included in jammy, but also reverted alignment to a previously used one. This also results in working binary under WSL1. * Cherry-pick upstream applied revert to alignment to resolve running gzip under WSL1. [Test Plan] * Use powershell to set default WSL version to 1 * Deploy WSL1, unpack and use updated gzip package * gzip --version should execute correctly under WSL 1 [Where problems could occur] * I cannot tell why performance improvement patches introduced alignment change, and if revert of the alignment change affects the performance. Note that this change aligns the codebase closer to what kinetic & upstream now are. [Other Info] * This bug fix is upstream commit https://git.savannah.gnu.org/cgit/gzip.git/commit/gzip.c?id=23a870d14a49803c6d2579071886c1acf497c9d1 --- gzip version 1.10-4ubuntu3 fails to run under WSL1 on Windows 19044.1620, making WSL pretty much unusable. bash: /usr/bin/gzip: cannot execute binary file: Exec format error ProblemType: Bug DistroRelease: Ubuntu 22.04 Package: gzip 1.10-4ubuntu3 ProcVersionSignature: Microsoft 4.4.0-19041.1237-Microsoft 4.4.35 Uname: Linux 4.4.0-19041-Microsoft x86_64 ApportVersion: 2.20.11-0ubuntu79 Architecture: amd64 CasperMD5CheckResult: unknown Date: Tue Mar 29 06:40:33 2022 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=pl_PL.UTF-8 SHELL=/usr/bin/fish SourcePackage: gzip UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/gzip/+bug/1966849/+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
