Upgrade Debian Packages

The following instruction is an example for upgrding Debian packages on UC-8112-ME series. For more infomation, please refer to UC-8100-LX Software User's Manual (for Debian 8)

General (system-wide) Upgrade

  1. Update the Debian package lists
moxa@Moxa:~$ sudo apt-get update
  1. Perform the upgrade command
moxa@Moxa:~$ sudo apt-get upgrade

Review the output messages and type "y" to confirm.

Upgrade a specific Debian package

  1. Update the Debian package lists

    moxa@Moxa:~$ sudo apt-get update

  2. Query the version information, confirm you could get the latest version on moxa reposiroty.

    moxa@Moxa:~$ sudo apt-cache policy uc8100me-syskernel
    uc8100me-syskernel:
        Installed: 2.3.0+memory
        Candidate: 2.3.1
        Version table:
            2.3.1 0
            500 http://debian.moxa.com/debian/ jessie/main armhf Packages
        *** 2.3.0+memory 0
            100 /var/lib/dpkg/status
            2.1.0 0
            500 http://debian.moxa.com/debian/ jessie/main armhf Packages
    

    In above case, we are trying to upgrade package "uc8100me-syskernel" and you can see the Installed, Candidate version is different. Candidate version is the one when we trying to install from remote what we will get.

  3. Update a package by name

    moxa@Moxa:~$ sudo apt-get install uc8100me-syskernel

    Here is the example output

    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    The following packages will be upgraded:
        uc8100me-syskernel
    1 upgraded, 0 newly installed, 0 to remove and 71 not upgraded.
    Need to get 9,780 kB of archives.
    After this operation, 414 kB disk space will be freed.
    Get:1 http://debian.moxa.com/debian/ jessie/main uc8100me-syskernel armhf 2.3.1 [9,780 kB]

    Unpacking uc8100me-syskernel (2.3.1) over (2.3.0+memory) ...
    Setting up uc8100me-syskernel (2.3.1) ...
    *** System successfully updated. ***
    *** Please reboot the system...***
    

    As you can see, Unpacking uc8100me-syskernel (2.3.1) over (2.3.0+memory) .... Now the package version of uc8100me-syskernel is 2.3.1 instead of the old version.

  4. Reboot

  5. Verify upgraded version (optional)

    moxa@Moxa:~$ dpkg -l | grep uc8100me-syskernel
    ii  uc8100me-syskernel            2.3.1                            armhf        Linux kernel modules on UC-8112-ME series
    

    If the installation isn't success, the ii will be something else.
