gzip exec format error under WSL1

Status changed to 'Confirmed' because the bug affects multiple users.

I am seeing the same error when I update Ubuntu 22.04 under WSL1:

Processing triggers for install-info (6.8-4build1) ...
sh: 1: gzip: Exec format error
install-info: warning: no info dir entry in `/usr/share/info/coreutils.info.gz'
sh: 1: gzip: Exec format error
install-info: warning: no info dir entry in `/usr/share/info/diffutils.info.gz'
...

Reported to WSL: https://github.com/microsoft/WSL/issues/8219

Note that only 1.10-4ubuntu3 is affected, so users can install gzip 1.10-4ubuntu1 and set the package on hold for the time being, until the issue is resolved.

Also affects: gzip (=1.10-4ubuntu4)

I download the file https://ftp.gnu.org/gnu/gzip/gzip-1.12.tar.gz
I Untar it tar xvzf with ubuntu 20
I copy all the files to Ubuntu 22
I run the ./configure
I run make
I run sudo make install
I exit the terminal
I log in again
and the new gzip 1.12 work very good

Just realized that my 22.04 installation was still running in WSL1... No more error after switching to WSL2.

Chiming in that it'd be great if this (gzip-1.10-4ubuntu4) continued to work in WSL1.

FWIW, gzip 1.10-4+deb11u1 on Debian Bullseye and 1.12-1 on Debian Bookworm do not have this issue.

Hello Bruno, or anyone else affected,

Accepted gzip into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/gzip/1.10-4ubuntu4.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

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
