Fix "python-devel version is too low for system upgrade" error during Linux migration - Server Migration Center

This topic explains why the python-devel version is too low for system upgrade error occurs during Linux migration with Server Migration Center (SMC), and how to resolve it.

Problem description

When you use SMC to migrate a Linux operating system, the following error message appears:

python-devel version is too low for system upgrade

Cause

The python-devel package installed on the source server is outdated and is incompatible with the system upgrade process.

Solution

Update the python-devel package on the source server, then retry the migration.

Connect to the source server. For more information, see Connect to an instance.
Run the appropriate command for your distribution to update the python-devel package: CentOS, RHEL 7, Alibaba Cloud Linux 2 (yum): RHEL 8+, Fedora, Alibaba Cloud Linux 3 (dnf): Debian, Ubuntu (apt): SUSE, openSUSE (zypper):
```
   sudo yum update python-devel
```
```
   sudo dnf update python-devel
```
```
   sudo apt-get install --only-upgrade python-dev
```
```
   sudo zypper update python-devel
```
Verify that the update succeeded: RPM-based distributions (CentOS, RHEL, Alibaba Cloud Linux, SUSE): Debian/Ubuntu: Confirm that the output shows an updated version of the package.
```
   rpm -qa | grep python-devel
```
```
   dpkg -l | grep python-dev
```
Run the SMC client and retry the migration job. For more information, see Run the SMC client.

What to do if the update fails

If the update command fails, try the following:

Repository unreachable: Verify that the source server has internet access and that the package repository is correctly configured. Run yum repolist (or the equivalent for your package manager) to check available repositories.
Package conflicts: Run sudo yum check (or the equivalent) to identify dependency conflicts, and resolve them before retrying the update.
Insufficient permissions: Make sure you run the command with sudo or as the root user.

If the issue persists, contact Alibaba Cloud technical support.
