[pkg-go] Bug#1033826: podman: Cannot load gzip compressed images
Control: reassign -1 golang-github-klauspost-pgzip 1.2.5-2 Control: affects -1 libpod Control: forwarded -1 https://github.com/containers/podman/issues/15944 Control: severity -1 important Hi Antonio, Thanks for your report. I've looked through the source code, and while the exact error message doesn't exactly match, I did confirm that the current debian/sid podman is indeed built with golang 1.19, and uses an older version of klauspost/pgzip that doesn't have that code change from https://github.com/klauspost/pgzip/pull/50. I'd argue it is necessary for golang 1.19. In order to fix this, the code change needs to go into pgzip and libpod needs to be rebuilt. -rt On Sun, Apr 2, 2023 at 6:51 AM Antonio Cebrián wrote: > Package: podman > Version: 4.3.1 > > > Podman cannot load images compressed with gzip.

[pkg-go] Bug#1033826: podman: Cannot load gzip compressed images
Package: podman Version: 4.3.1 Podman cannot load images compressed with gzip. Uncompressed images or bzip2 compressed images work right therefore it seems to be a problem related to gzip handling.
