  1. Re: No internet on otherwise good wifi connection

    Solved? What did you do?
    BTW, did you try booting from an Ubuntu Install flash drive and going into "Try Ubuntu" ... to see if that works fine? That's an easy way to see if it is a hardware issue...

    Re: Help with crontab & apache

    Which crontab did you edit - your userid's or root's?

    If you edited your own, then it will run with that userid and permissions. Typically, a normal login userid cannot write (and shouldn't be...

    To find if any rdiff-backup versions are in a tree, use

  5. Re: Is possible use 2 mount point in same partition ?

    I think we need to clarify that disks aren't mounted. File systems are what we mount. Just like an mp4 file is just a container for a few different video/audio types of data, file systems can be...

    Re: / full 91%

    I'm guessing you mean 25G is used, not the total size.

    Gparted shows the partition size.
    du shows the used amount of block space it can find.

    If du and parted/fdisk show different used amounts...

    [ubuntu] Re: Moving Files

    A typo?

    sudo isn't needed. sudo abuse is how people get into permission problems. If there is a permissions issue, fix that first. In general, running sudo chown -R $USER:$USER ~/ is safe. If...
  9. Re: Ubuntu Server 20.04.02 hangs. NVME I/O error?

    I'd check for high temperatures. Small cases don't often have great cooling and NVMe devices using an m.2 slot sometimes need a heatsink to help effectively cool them down.

    My CPU is currently...
  10. Re: Seeking advice on internal Blu Ray Writer

    [ubuntu] Re: ssh /bin/sh no such file

    rsync defaults to using ssh tunnels and has for 15+ yrs. That is the best answer here.
    scp is going to be deprecated - I don't know what that means.

    sftp ~= FTP

    After running,

    NEVER mount a file system more than 2 places at the same time, unless you are using a -o bind option. Pain comes with doing that, if it is even allowed.
