Linux – How to solve “tar: invalid magic” error on Linux Alpine

alpine-linuxtar

I'm installing sqlite on Alpine Linux. I download sqlite-autoconf-3130000.tar.gz but tar could not open it. I tried this answer but it's not working. tar gives this message:

tar: invalid magic
tar: short read

I wrote these commands.

wget https://www.sqlite.org/2015/sqlite-autoconf-3090100.tar.gz
tar -zxvf sqlite-autoconf-3090100.tar.gz

Try to install the tar package (apk add tar). Busybox tar (default) doesn't support all features.

“invalid tar magic” on OpenWRT

The version of tar on OpenWRT is a smaller one than the one on full-blown systems, designed to fit small devices (it's BusyBox.) To keep small, it lacks features such as the automatic detection of compressed archives.

Try declaring the compression format manually with the -z option:

tar -xvzf ejdk-8u65-linux-arm-sflt.tar.gz

Support for gzip in the tar utility is an optional feature that may or may not be enabled on OpenWRT. If you don't have it, call zcat (or gzip -dc) explicitly:

zcat ejdk-8u65-linux-arm-sflt.tar.gz | tar -xvf -
