@hanugm are there any particular requirements for that?

I mean what kind of specifications are useful for what you want to do?

The market here seems really quite bad these days. No good deals

Rome Escabillas

glad to be here, few months ago I've installed and upgrade my ubuntu to desktop and then I started to create a apache2 to host our own company website, everything is good but when I've added devmin for my control, I am starting to get some issues.

hanugm

04:35

@Zanna Yeah true. So much cost.

One requirement is GPU. I need to do computer vision tasks.

Zanna

05:11

@hanugm so you need a nice graphics card that actually works with Ubuntu?

Q: Ubuntu 20.04.01 not booting after kernel update

I just updated my PC that is running the latest version of Ubuntu (20.04.01). I made a system update and that update included also a kernel update (from kernel 5.4.0-42-generic to 5.4.0-45-generic).

@technastic_tc that does not tell if that package is installed. Try apt policy

@vladzouth is there not a "do not disturb" button?

technastic_tc

@jokerdino I'm a noob in Ubuntu. Which command should I exactly type? Should I type apt policy?

jokerdino

@technastic_tc apt policy gir1.2-gtksource-3.0

actually, try installing it: sudo apt install gir1.2-gtksource-3.0

technastic_tc

```
gir1.2-gtksource-3.0:

jokerdino

yeah, not installed

technastic_tc

I installed it and it's still the same.

But I found one new detail. I'll edit my question and add the detail.

jokerdino

14:23

can you open gedit from terminal and see if you get any specific error message?

technastic_tc

@jokerdino How do I open from terminal? Should I type gedit in terminal?

jokerdino

yes please

technastic_tc

No error message.

jokerdino

@technastic_tc any warnings or anything when trying to enable the plugin?

technastic_tc

@jokerdino Please refer the screenshot above

@technastic_tc install python3-gi and try again?

technastic_tc

Is this the command to install: sudo apt install python3-gi?

My ubuntu machine suddenly stared beeping quite loudly then I tried rebooting it and powering it off for a while, but the beeping continues, and it gets stuck at 'Welcome to emergency mode'. And advice what caused it and how to fix it?

ubuntu boot cifs

Zanna

@technastic_tc have you done anything to affect your python configuration? Why would python3 be not found?

@technastic_tc I recommend adding this screenshot to your question

technastic_tc

@Zanna I'm editing my question now

Zanna

:)

technastic_tc

@Zanna I tried upgrading Python some time ago.. maybe I messed up something :/

Zanna

I expect that would be the issue...

jokerdino

15:16

@technastic_tc how's that?

Zanna

do you remember exactly what you did? Or do you have a record of it, in your .bash_history or /var/log/apt/history.log or /var/log/apt/term.log or anything?

(old logs would be there too - they get compressed but you can zgrep or unpack them, if needed... but perhaps you did not use APT for any of the things you did)

sorry I'm just going to do some housework...

technastic_tc

@Zanna It's ok. I'll check how I updated and get back

I guess I followed these instructions: techpiezo.com/python/install-python-3-8-3-in-ubuntu-20-04-lts

in the end of the article they gave two suggestions. One, to replace (or overwrite) already installed version 3.8.2 of Python; two, to install Python v3.8.3 alongside the Python v3.8.2.

I did the first option

dpaste.com/CXUCDQ7YT whenever trying to start up a vagrant server for a python app i am receiving this any idea as to what I should do to sort it out? I have tried turning off the hypervisor in my system but that turned to be a bad idea as many problems came up... any assistance would be great

Zanna

@technastic_tc aha! I think this is the right track... hopefully someone can figure out how to fix it... back later

technastic_tc

15:32

@Zanna :)

Zanna

What does file /usr/bin/python3 say?

why did you want to upgrade python? Did you need a new feature or something?

technastic_tc

/usr/bin/python3: symbolic link to python3.8

Zanna

well, that's as it should be

technastic_tc

@Zanna I was gonna learn Python programming. So I thought of upgrading python.

Zanna

so still unknown why gedit doesn't find it

hmm so I expect going back to 3.8.2 wouldn't be a problem for you, if that turned out to be the solution?

technastic_tc

15:43

@Zanna Yeah. I would not mind going back to 3.8.2.

user3140225

@technastic_tc A bit off-topic, but maybe helpful in general. As I have found out from personal experience and also from many questions here, it's not a good idea to mess with the default Python. If you need a Python version other than the one that comes preinstalled with the OS, the best option you have, in my opinion, is install Anaconda and create a virtual environment with the desired version.

Also, do you have a specific reason for working with gedit? You could try another editor, like VS Code, Atom, not vim, etc.

jokerdino

why not vim?

user3140225

@jokerdino Mainly it was meant as a subtle joke

But since @technastic_tc is a new user still learning the OS, perhaps learning vim could be hard for them for the time being

Zanna

@user3140225 this

technastic_tc

@user3140225 Thanks for the suggestion

@user3140225 I am not using gedit for learning Python. I am using Python IDLE.

I was casually looking into settings of gedit and I found the option of External Tools. I tried enabling it and then I noticed the error

jokerdino

15:54

@user3140225 noted thanks

user3140225

@technastic_tc I see. IDLE is good, but pretty basic. I use Jupyter Lab in conjunction with VS Code, the first for testing code (the interactivity it offers is awesome) and the second for finalizing it. Perhaps you should give it a try.

If you ever decide to install Anaconda and need any help, don't hesitate to ping me.

jokerdino

thanks, will do

@user3140225 My teacher has been asking me to install Anaconda Navigator and Spyder IDE. I'll definitely ping you in case if I have any doubt!
