The small linux problem thread

I’ve installed https://github.com/nicolargo/glances via pip on my PI 3B+ but pip didnt add it to the path so how would I add it to the path so I can launch it from terminal

Find out where it got installed (try locate glances) and add the executable to preferably your user’s path.

In ~./bash_profile have PATH=$PATH:[PATH_TO_GLANCES_EXECUTABLE_PARENT_DIRECTORY]

Or, my preference, have something like PATH=$PATH:$HOME/.local/bin:$HOME/bin and make a symbolic link in ~/.local/bin or ~/bin to wherever glances is located.

cheers for the reply but I realized I was a derp and must’ve not checked if I could install it with apt so I just installed it that way

sceps · August 13, 2019, 4:08pm

Yeah, glances is also available through repos usually, but not always up to date.

Trooper_ish · August 13, 2019, 4:50pm

Shit, that’s good.
Might you create a thread for posterity?

How to make sure your bootable USB from ISO will actually boot Wikis & How-to Guides

Have you ever tried “burning” an ISO to a USB device only to be frustrated that IT. JUST. WON’T. BOOT? Here’s how to check if the ISO will be bootable on USB, and how to fix it if it won’t. Two simple steps: Check with file if the ISO is a hybrid. file [/path/to/ISO] If it’s a hybrid, the output will look something like this and the USB should be bootable: [/path/to/ISO]: DOS/MBR boot sector; partition 2 : ID=0xef, start-CHS (0x3ff,254,63), end-CHS (0x3ff,254,63), startsector 268, 0 sectors If it is not a hybrid, you can expect to see something like this which likely won’t boot from USB: ISO 9660 CD-ROM filesystem data '[LABEL]' (bootable) Make the non-hybrid ISO a hybrid: isohybrid [/path/to/ISO] Or use flag -u or --uefi to make it UEFI bootable: isohybrid -u [/path/to/ISO] That’s it! Just use your preferred method to get the ISO onto the USB device, such as Gnome Disks, or sudo dd bs=4M if=[/path/to/ISO] of=[/path/to/USB] conv=fdatasync, and enjoy booting.

I’m having a Bluetooth pairing problem with Fedora 29. Every time the system starts up or reboots, my Bluetooth device (a Logitech M535 mouse) has to be manually re-paired. IOW, I have to manually start blueberry (blueman won’t work for some reason), hit the pairing button on the mouse, then press the “Connect” toggle for the mouse to pair, connect and operate. Is there a correct/better way to do this, or a script I can put in my XFCE “Session and Startup” to reconnect properly? If it matters, I have a no-name USB bluetooth adapter using the “btbcm” module.

Mastic_Warrior · August 20, 2019, 2:03am

It is interesting that blueman does not work. You should be able to store the MAC of your mouse in a trusted file after pairing. I did this on my rpi ages ago for a few audio devices but, I don’t really do much with it anymore (rpi 1 B, not plus model). Again using Bluez and Blueman here.

Do you know what errors you are getting from bluman/bluez? That could be part of your issue.

imrazor · August 20, 2019, 2:08am

Like so many Linux driver problems, my Bluetooth issue was caused by a missing firmware file. Somehow blueberry was able to work around the problem while blueman wasn’t able to deal with it. “dmesg | grep -e blue” found the missing firmware name, and a Google search found the proper firmware file. Once in /lib/firmware/brcm, the pairing persisted across reboots.

Awesome. Thanks for adding your resolution.

Problem:

Can’t install ukuu through apt. I added the repo and updated but …

E: Unable to locate package ukuu

I also found out that it is a paid program now…
So I guess I need something different or a tutorial to upgrade the kernel manually.

Diffident · August 25, 2019, 7:23pm

It’s still on github, no need to use the paid version.

No need to upgrade to the paid version, its just fetches kernels from https://kernel.ubuntu.com/~kernel-ppa/mainline/

fixed link

noenken · August 25, 2019, 7:32pm

I know that but there already isn’t a version for ubuntu 19.04 in the repo and for a piece of software that updates the core of my OS, not getting updated anymore is a death sentence.

SgtAwesomesauce · August 25, 2019, 7:35pm

I don’t think so. It’s just a frontend to a package manager. It’s really not that bad.

If you want to do it manually, here:

Also, is it so bad to pay the $12?

noenken · August 25, 2019, 7:57pm

Yes, sure. It’s the couple bucks why I don’t wanna use it anymore… exactly.

But thanks for the link.

SgtAwesomesauce · August 26, 2019, 6:23am

Happy to help!

Is it really that hard to add repos and/or just compile your own kernel? That is a serious question. Maybe I have been using GNU/Linux for too long now.

I feel this is the reason why I keep hearing, Linux is so hard and stupid because you have to use other repos and software to maintain it. In the case of APT based systems, it could not be any easier to add a new repo or manually install deb packages with dpkg.

I am not digging into anyone here, but seriously, if you do not have the time to learn how to do something properly, then maybe you just are not ready to use that thing. I mean, people are having issues reading quick guides for products now. They literally made the quick guide because they knew you were too lazy to RTFM. You cannot even read a piece of paper with pictures now? Really

Not really, but compiling your own kernel on a regular basis ends up sucking up a lot of your time.

Not really, but compiling your own kernel on a regular basis ends up sucking up a lot of your time.

Does it though? It’s not as bad as chromium, only takes a few minutes if you do localmodconfig
