Make sure you check in `SOLIDCOR_KERNEL_<version number>-<build number>_LNX.zip` package to ePO - On-prem in the same branch as the `SOLIDCOR_FULL_<version number>-<build number>_LNX.ZIP` package. > [!NOTE] > Note > > Ensure that you select TACC version 6.6.6 or later. A message appears asking to overwrite the package. Click **OK** to check in the package. 1. Download the .zip file from the Trellix download site to a temporary location on the ePO - On-prem server. 2. Log on to the ePO - On-prem server as an administrator. 3. Select **Menu** → **Systems** → **Main Repository** → **Check In Package**. 4. For Package type, select **Product or Update (.ZIP)**. 5. Click **Choose File**, select `SOLIDCOR_KERNEL_<version number>-<build number>_LNX.zip`, click **Choose**, then click **Next**. 6. Select **Current** as the branch. 7. Click **Save**. You can verify the package versions on the managed endpoints using the **rpm -qa** command (for rpm based distributions) or **dpkg -l** (for debian based distributions). #### Update TACC for Linux 6.6.11 with the latest kernel packages Update TACC for Linux 6.6.11 with the latest kernel modules for the Linux kernel package. - You must download TACC for Linux 6.6.6 or later from **Software Catalog**. - Make sure you download the latest TACC kernel modules from the Software Catalog in the same branch as `SOLIDCOR_KERNEL_<version number>-<build number>_LNX.zip`. > [!NOTE] > Note > > Ensure that you select TACC version 6.6.6 or later. Place the endpoint in update mode before installing the new package. A message appears asking to overwrite the package. Click **OK** to check in the package. 1. Log on to the ePO - On-prem server as an administrator. 2. Select **Menu** → **Systems** → **System Tree**, then select a group or systems. 3. On the **Assigned Client Tasks** tab, click **Actions**, then click **New Client Task Assignment**. 4. Complete these options, then click **Create New Task**: 1. For product, select **Trellix Agent**. 2. For task type, select **Product Update**. 5. Enter the Task name and check in TACC kernel modules for Linux 6.6.11 under package types. Uncheck all other boxes and click **Save**. 6. Select the Schedule type as **Run immediately**, then click **Save**. The new task appears under the tasks list. 7. Select the endpoints where the update has to run. Click **Wake Up Agents**. Wait for the task to complete. You can verify the package versions on the managed endpoints using the **rpm -qa** command (for RPM-based distributions) or **dpkg -l** (for Debian-based distributions). #### Upgrade standalone RPM endpoints with the latest kernel package Upgrade your RPM endpoints with the `SOLIDCOR_KERNEL_<version number>-<build number>_LNX.zip` kernel package using the command line. You must have TACC for Linux 6.6.6 or later installed and running on your endpoint. Place the endpoint in update mode before installing the new package. 1. Copy `SOLIDCOR_KERNEL_<version number>-<build number>_LNX.zip` to your endpoint. 2. Unzip the package: `SOLIDCOR_KERNEL_<version number>-<build number>_LNX.zip -d tacc_kernel_module` . 3. Run these commands to upgrade the kernel module. *For Application Control* ```plaintext cd tacc_kernel_module ./mapkg_install.sh service scsrvc restart rpm -qa | grep -i solidcore --> shows solidcoreS3 and solidcoreS3-kmod version 6.6.11. ``` *For Change Control* ```plaintext cd tacc_kernel_module ./mapkg_install.sh service scsrvc restart rpm -qa | grep -i solidcore --> shows solidcoreS3 and solidcoreS3-kmod version 6.6.11. ``` > [!NOTE] > Note > > A system reboot is required after installation for the new kernel module to load. #### Upgrade Debian endpoints with the latest kernel package Upgrade your Debian endpoints to the `SOLIDCOR_KERNEL_<version number>-<build number>_LNX.zip` kernel package using the command line. You must have TACC for Linux 6.6.6 or later installed and running on your endpoint. Place the endpoint in update mode before installing the new package. 1. Copy `SOLIDCOR_KERNEL_<version number>-<build number>_LNX.zip` to your endpoint. 2. Unzip the package: `SOLIDCOR_KERNEL_<version number>-<build number>_LNX.zip -d tacc_kernel_module`. 3. Run these commands to upgrade the kernel module. *For Application Control* ```plaintext cd tacc_kernel_module ./mapkg_install.sh service scsrvc restart dpkg -l | grep -i solidcore --> shows solidcoreS3 and solidcoreS3-kmod version 6.6.11. ``` *For Change Control* ```plaintext cd tacc_kernel_module ./mapkg_install.sh service scsrvc restart dpkg -l | grep -i solidcore --> shows solidcoreS3 and solidcoreS3-kmod version 6.6.11. ``` > [!NOTE] > Note > > A system reboot is required after installation for the new kernel module to load.
