  1. [ubuntu] Re: remove swap partition and create swap file after upgrading

    swapoff then delete the swap partition.

    You can have 1,2, 20 swap partitions or files. swap files have some limitations. Be certain you understand and can live with those.

    warning: Fail to read ppd=/etc/cups/ppd/HP-Fax-4.ppd file
    warning: Insufficient permission to access file /etc/cups/ppd/HP-Fax-4.ppd
    Permissions. Fix this first. Appears only read is needed.

    [SOLVED] Re: rsync over ssh errors

    sshfs is really slow. Best to be used for temporary stuff or over the internet.
    Either use nfs or cifs when on the same LAN. Both will be 2-4x faster than using sshfs.
  5. [ubuntu] Re: you do not have permission to remove this software

    Don't use rdp. Use ssh -X. A full desktop isn't very efficient.

    [SOLVED] Re: rsync over ssh errors

    If you type

    Does all the storage involved show up? Both the source and the target? If not, no, that is not correct.

  7. Re: How do I upgrade Ubuntu 18.04 up to 18.04.4 LTS?

    Run:

    sudo apt-get update

    That should bump up the system to 18.04.5


    $ lsb_release -a

    [SOLVED] Re: rsync over ssh errors

    rsync over SMB? That's confusing.
    How about "rsync to an SMB mount"?
    Just mount the SMB/CIFS to the machine where the files are located and use rsync. That works. I use it a few times a week.

    Don't use the GUI. GUIs lie.

    I don't know what you mean by "mixing memory modules."

    You can't mix DDR3 and DDR2. They don't work that way. Mixing speeds of some RAM won't work. I vaguely...
