I was using centOS8 and try to execute yum install -y gcc tcl and failed. The error shows it has some problem with signature check or something at rpm install process.The console log is like
error: /var/cache/dnf/base-82351eca59c28538/packages/cpp-8.5.0-21.el8.x86_64.rpm: signature hdr data: BAD, no. of bytes(9088) out of range
and
Error: GPG check FAILED.
I tried to upgrade my rpm installer and get same problem, and yum update didn't work either. I tried to use --nogpgcheck, it still didn't work.

You have two issues here:

1- error: /var/cache/dnf/base-82351eca59c28538/packages/cpp-8.5.0-21.el8.x86_64.rpm: signature hdr data: BAD, no. of bytes(9088) out of range: there are multiple solutions for it:

  • execute the following command dnf clean all
  • if the command above did not fix the issue: then follow the steps below:
    • curl ttps://vault.centos.org/8.5.2111/BaseOS/x86_64/os/Packages/centos-gpg-keys-8-3.el8.noarch.rpm -o centos-gpg-keys-8-3.el8.noarch.rpm assuming you are using Centos 8 you can get the latest version of this by visiting the main website.
    • rpm -i centos-gpg-keys-8-3.el8.noarch.rpm (again if the version is different then you need to adjust the package name)

2- Error: GPG check FAILED there are a couple of solutions for it.

  • sudo dnfclean all , sudo yum clean metadata , and dnf clean all then rename /etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial then try to install your package again.
  • Disable GPG check temporarily if the solution above did not fix the issue
  • Check if you have a security application that might cause an issue such as Zscaler.

  • I indeed tried clean all command and still not function. I also tried to install local package here's my console log. rpm -i rpm-build-4.14.3-31.el8.x86_64.rpm error: rpm-build-4.14.3-31.el8.x86_64.rpm: signature hdr data: BAD, no. of bytes(16520) out of range error: rpm-build-4.14.3-31.el8.x86_64.rpm cannot be installed

The bug is described here: https://bugzilla.redhat.com/show_bug.cgi?id=1896046

It is fixed in version rpm-4.14.3-12 and above, but because of the bug, a new version from the repo cannot be installed. You can manually download and install an earlier version like rpm-4.14.3-26.

First try if you can upgrade:

dnf upgrade rpm rpm-libs -y

If it does not work try the next steps:

Verify that you are using version 4.14.3, that has this issue:

# rpm --version
RPM version 4.14.3

If you have another version, do not continue with the next steps.

Download the older version of RPM and its libraries:

wget https://rpmfind.net/linux/centos/8-stream/BaseOS/$HOSTTYPE/os/Packages/rpm-4.14.3-26.el8.$HOSTTYPE.rpm
wget https://rpmfind.net/linux/centos/8-stream/BaseOS/$HOSTTYPE/os/Packages/rpm-libs-4.14.3-26.el8.$HOSTTYPE.rpm

Extract the RPM packages using rpm2cpio and cpio:

rpm2cpio rpm-4.14.3-26.el8.$HOSTTYPE.rpm | cpio -idmv -D / -u
rpm2cpio rpm-libs-4.14.3-26.el8.$HOSTTYPE.rpm | cpio -idmv -D / -u

Upgrade RPM using dnf:

dnf upgrade rpm rpm-libs -y
