Thanks. Could you please consider accepting a fixed patch rather than closing the bug as won't fix? While this is not an issue with traditional loaders, users of WSL would certainly appreciate strip not generating binaries crashing there. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to binutils in Ubuntu. https://bugs.launchpad.net/bugs/1843479 Title: gzip in Ubuntu Eoan results in Exec format error on WSL1 Status in binutils: Confirmed Status in binutils package in Ubuntu: In Progress Status in gzip package in Ubuntu: In Progress Bug description: Summary: Running gzip on WSL1 results in the following error: $ gzip -bash: /bin/gzip: cannot execute binary file: Exec format error What I expect to happen: gzip executes correctly on WSL1. What happens instead: gzip fails with an Exec format error. Notes: I suspect a change in how gzip is being built for Eoan is causing issues with ELF parsing on the WSL1 translation layer. For example: On Disco with gzip 1.9-3: $ file /bin/gzip /bin/gzip: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=efa859c26eaf8e035efe9a139361e2a60cd17b3e, stripped On Eoan with gzip 1.10-0ubuntu3: $ file /bin/gzip /bin/gzip: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=bc0f5994544c2a469d04c914bf4bf44b4ded6040, for GNU/Linux 3.2.0, stripped Eoan ships with gzip 1.10, while Disco ships with gzip 1.9, but I do not believe this is an issue in 1.10 because this error does not occur when building gzip from GNU project source on Ubuntu Eoan. Justifications: WSL1 will need to be patched in future Windows builds for this change in ELF. However that patch will likely not be backported to older builds of Windows, including Windows Enterprise/Server 2019. To ensure Eoan can run on current and older builds of Windows Ubuntu should consider looking at how it's building gzip and see if it can be made to 'play nice' until WSL1 can be updated.
