    Help downloading and installing Discord for Ubuntu

    Posted: 15 Aug 2019 11:57 AM PDT

    SOLUTION The correct command to use is

    sudo apt install dependency1 dependency2 

    It also demanded that those dependencies had other dependencies, so I had to get those as well. Terminal was also helpful by showing me a new command

    sudo apt --fix-broken install 

    which fixed the currently unfinished installation of Discord. I can speculate you can select which broken install to finish or can finish them all if there were multiple unfinished/broken installs.

    Also, I noticed how much more important it is to pay attention to Terminal because it told me through a sea of text that some packages were no longer needed and I can use

    sudo apt autoremove 

    After that, discord was all setup.

    PROBLEM

    Hello, I'm using Ubuntu 18.04.3 LTS (64bit).

    I went to Discord's website and downloaded the .deb package. I also used terminal and tried and successfully downloaded with

    sudo snap install discord . 

    Now, here comes the problem. I'm trying this command

    wget -O discord.deb "https://discordapp.com/api/download?platform=linux&format=deb" 

    but couldn't install when trying

    sudo dpkg -i /path/to/discord.deb . 

    I'm given three dependency errors - libgconf-2-4, libappindicator1, and libc++1. I tried to use sudo apt-get for each one but it doesn't work. I'm not sure if I want or need them since I can just easily do it through the GUI installer Discord's website provides. I'm guessing the installer will just install those dependencies, but I'd like to learn how to do this through the third method that I'm stuck on.

    A few other questions.

    How does someone get the URL https://discordapp.com/api/download?platform=linux&format=deb?

    Why wget instead of sudo apt-get?

    I used sudo apt-get for youtube-dl but it isn't available for discord.

    Thanks for reading.

    Noob wants to update mint

    Posted: 15 Aug 2019 02:08 PM PDT

    Brother just gave me an old laptop that runs on mint. He said the software was downloaded in 2013 and so far I've already had trouble downloading the latest chrome browser so I assume it needs an upgrade. If I were to download the most recent software will I need to backup his files first? The download itself seems pretty straight forward but this is day 1 with linux for me and I dont want to lose any important files. Any help, links, or videos would be appreciated.

    Partitions and Mounts

    Posted: 15 Aug 2019 10:18 AM PDT

    So I recently built a PC and decided the to run two M.2 drives, one for Linux Mint 19.2, one for Windows. I would just like to know: 1. How do I safely use Timeshift? 2. Have I done it correctly? I am all for learning by experimentation, but I really don't wanna mess up my PC. Here is what I did when I was setting it up (I couldn't find a tutorial which explained how to do this from start to finish, so cobbled together a few other tutorials I could find.) FYI I am using a UEFI motherboard.

    1. I installed windows on nvme0n1.
    2. Booted from a Mint USB.
    3. Created a GPT partition table on nvme1n1 (my second M.2).
    4. Created an ESP partition, 300 MiB FAT32 at the start of the drive, gave it the flags boot and esp.
    5. Then started the installation procedure, clicked "something else" when it asked about storage, made a partition for /, made a home partition mounted on /home, and made a swap area (I know, I used too much space for swap and will change it when I figure out how).
    6. I let GRUB2 take care of the rest.

    Pics are here.

    And the Windows partition.

    And from what I can gather, it works fine. I can play games on the windows side, and do everything else on the Mint side. GRUB2 asks what I wanna use when I boot up, and that is great. But to return to my previous questions, when I was looking around to figure out how to work Timeshift, this is the default setting, with this as the advanced settings. Is that correct? If so, why? Because restoring /boot/efi to the Windows side seems a bit weird. Also, any recommendations on where to start learning about all this? Do I actually need that ESP partition I made before installation?

    How to backup the whole system?

    Posted: 15 Aug 2019 09:05 AM PDT

    So I want to distro hop and I want to backup my currrent setup which I spent a lot of time on. On windows I can make a ghost copy of the system but what is it's equivalent on linux? I have heard timeshift can do some kind of backup.

    Can anybody suggest something for me? Thank you very much.

    mounting partitions

    Posted: 15 Aug 2019 12:18 PM PDT

    I got a nvme ssd and a hdd and I got them mounted the following way:

    nvme is /

    hdd is /home

    what I want to know now is: would it bit possible to create a folder in /home which writes/reads from the nvme? So that I can have a library of certain programs/games that I want stored on my nvme ssd instead of my hdd? Or what would be the most elegant way to do so?

    What information is stored in Linux systems that could be interesting to analyse?

    Posted: 15 Aug 2019 07:55 AM PDT

    For example, I only recently found out about sar files.

    I'm wondering what else there is that's already available on my system that I might be able to play around with.

    Just a source of data-sets that I hadn't really thought about I guess.

    thanks

    Can I use wifi on live boot?

    Posted: 15 Aug 2019 07:09 AM PDT

    I have a laptop on which I'd like to use live Linux mint but don't want to install it. When I boot into Linux mint there's no option for wifi or wireless network.

    Best distro for an old ASUS netbook?

    Posted: 15 Aug 2019 08:51 AM PDT

    I have an ASUS EeePC 900 and I want to install a Linux distro. I've tried some distros before, but they don't run very well. Windows 7 performs well tho. Here are the specs:

    CPU: Intel Atom (1.6 GHz)

    RAM: 1 GB

    Screen (just in case): 1024*600

    What should I try?

    Make succeeds but fails to load library on run.

    Posted: 15 Aug 2019 07:51 AM PDT

    Currently working in Redhat 7.6 and I have a c++ project that has manually configured makefiles. A unit test framework takes all the makefiles, builds them into a test library, then runs the unit tests.

    My error comes when I try to run the built library. Make shows no errors, but when I try to run it I get:.

    Failed to load library: ./libraryfilename : undefined symbol: jsjsh&##&SourceFileName$&@sjs

    I know this Source file is generally correct. It Makes on its own with no errors, and passes it's unit tests.

    I used the nm tool on the said library to find undefined symbols, and it gives only one, the same one in the error output (garbage text+SourceFileName).

    Are there any other tools that would help me figure out what file the undefined SourceFile symbol is included from(it's included in multiple places).

    I'm looking for tools, or ways to get more information. I understand that I haven't really given enough for a straight answer.

    Thanks!

    Cannot write to CIFS share unless root (Linux Academy Lab)

    Posted: 15 Aug 2019 06:55 AM PDT

    OS: RHEL 8

    I am going through the RHCSA file share lab and I'm struggling with CIFS. The file share from my server mounts, but I cannot write to it on the client if I am the standard cloud_user that their VMs ship with. I've been racking my brain for about two hours. Obviously, because I have been using sudo, both the shared file and the mount point are both owned by root.

    On my server, I have done the following:

    sudo yum install samba sudo mkdir /mnt/sambaStore sudo chmod 777 /mnt/sambaStore vim /etc/samba/smb.conf and appended: [share] writeable = yes path = /mnt/sambaStore browseable = yes sudo useradd user sudo smbpasswd -a user entered "password" as the password sudo systemctl start smb 

    On the client:

    sudo yum install cifs-utils sudo mkdir /mnt/samba sudo mount -t cifs //10.0.1.100/share /mnt/samba -o username=user,password=password 

    Once in the file share, using "touch" gets a Permission Denied error. I have been able to write to the share on my client as the root user

    Change default tty for graphical session

    Posted: 15 Aug 2019 06:00 AM PDT

    I use Fedora, which by default has the graphical session in tty1 and the other tty's are just terminals. However, likely due to me using tty2 to reinstall GNOME when it refused to log in, my graphical session is started in tty2 after boot. tty1 also has a graphical session running, but it isn't logged in automatically like in tty2. I'd like to return to Fedora's default tty configuration, so I need to:

    1) Set tty1 as the tty that is used right after boot.

    2) End the graphical session in tty2.

    What's the best way of going about this?

    Bonus question: how significant is the performance loss when running two graphical sessions in separate tty's?

    Interrupted partition moving

    Posted: 15 Aug 2019 05:50 AM PDT

    so I'm a filthy dualbooter hate me it's ok

    so the point was that I was resizing and moving my windows partition in kde with kde partition manager and I THINK what happened was my laptop died in the process and now the windows partition is labeled as just a basic partition and not as ntfs as I imagine it should be and now I can't boot it normally and get a windows blue screen recovery screen thingie.

    now I'm looking for tools that might help me fix this if it's fixable at all. The data on that system is not that important but I still find this as an opportunity to learn something so if you guys could direct me in a right direction I would be very grateful. also not sure what info would be useful to know about my case so let me know.

    And sorry for my formatting and post structure I'm more of a reddit-lurker type of guy and don't post much haha

    How to switch to a different tty on a guest GNU/Linux distro running in Virtualbox when your host is itself a GNU/Linux distro?

    Posted: 15 Aug 2019 05:07 AM PDT

    Suppose you want to switch to tty3 on your guest OS,

    Hold Ctrl(Right) + Alt(Right) + Shift(Right) and quickly press F3 two times(just as fast as you do double click on mouse) while keep holding above keys, and it will switch.

    Problems with dual monitors using an Asus laptop

    Posted: 15 Aug 2019 03:41 AM PDT

    Hi guys! I installed linux mint in my laptop and everything works out of the box except when i try to use a second monitor... I admit that my laptop is pretty bad (it doesn't have any graphic card, and its cpu isn't that great) but i don't have any other problem.

    When i connect a new screen, some black artifacts appear on the screen and my mouse cursor completely bugs out (it divides into 3/4 cursors and flickers).

    I don't think that this issue is linked to linux mint because i couldn't find anyone with the same issue via Google.

    My second monitor is connected to my laptop with an adaptor (DVI -> HDMI), could it be the cause of this problem ???

    Edit: My cpu is an Intel Pentium if that can help.

    New to Linux - RHEL 7 or 8?

    Posted: 15 Aug 2019 02:51 AM PDT

    Hi all,

    I'm new to Linux and Reddit :-)

    I've been asked by my company to become RH Admin certified. I have the option to of taking the training and exam for either RHEL 7 or 8. I'm new to admin and limited technical background - my job is usually high-level architecture design / data analysis for clients wanting to move their legacy environments to cloud. I would appreciate getting thoughts and recommendations on which version of the OS you prefer and would see being useful going forward.

    Thanks :)
