@FaheemMitha I ran into this post: goo.gl/vIlyij from a while back. Your answer describes my current situation exactly, my python 3 is actually 2.7 but what do i do next? how do i fix my python3 installation? apt-get stops whenever i try to remove or reinstall because it keeps throwing those ascii errors. Thanks for any help.

@user3504732 Hi. Have you posted a question about this?

I think someone just did post something similar, but I'm not sure if it was you.

And yes, I remember that question. That was a year ago? Scary.

@FaheemMitha no i haven't posted a question about this, I found that one and came here looking for you

@user3504732 Ah. Well, post a question first. You could reference that question/answer. Just say there what you are asking here.

And what you do depends on your exact situation.

First, do you have any local installs of python?

Run dpkg -C. What's the output?

ok so the machine in question is refusing to boot currently, possibly for unrelated reasons. If i don't get it working in the next few minutes i'll probably just end up reinstalling the OS. but thank you for your time. If I am still having this problem i'll post a question about it tomorrow.

@user3504732 Ok. Note that something as simple are recreating the symlink correctly could fix the problem, but it really depends on your exact situation.

Also, it's a good idea to figure out what you did wrong, so you don't repeat it.

I'm still really curious as to what i did wrong, but i can't find out now with the computer refusing to boot into ubuntu, and that's not a problem that I really feel like troubleshooting. I'll try my best to recreate the issue later though :)

@user3504732 I wouldn't worry about it. But feel free to post a question if you want. Just (a) reference the other question and (b) explain why the question isn't a dupe, otherwise people will try to close it.

John Goerzen is a systemd convert

Clearly, he has succumbed to the lure of the Dark Side.

Surely you've been convinced to run apt-get install systemd-sysv now!

@derobert Dark chocolate cookies, presumably.

When I run systemctl, I get this in red. Is this bad?

● systemd-modules-load.service                                       loaded failed failed    Load Kernel Modules

@FaheemMitha: wiki.archlinux.org/index.php/systemd#Troubleshooting

@Sukminder Thanks.

@FaheemMitha journalctl -b _SYSTEMD_UNIT=systemd-modules-load.service might help

@derobert Mar 11 21:37:49 orwell systemd-modules-load[265]: Failed to insert 'ipmi_si': No such device

possibly you have that in your /etc/modules?

@derobert No, /etc/modules only has loop.

or you have it in {/etc/,/run,/usr/lib}/modules-load.d

I suspect you have an ipmi package installed that plopped a load in for you...

dpkg -l | grep ipmi
ii  ipmitool                          1.8.14-4              amd64                 utility for IPMI control with kernel driver or LAN interface

Should I get rid of these? I have no idea why they are there.

@FaheemMitha if you don't have anything that uses IPMI, you can get rid of it

lists.debian.org/debian-user/2015/12/msg00729.html

it's possible that path wasn't documented in jessie: bugs.debian.org/cgi-bin/bugreport.cgi?bug=808997

@derobert Yes, I see. Apparently I could also upgrade. But I don't even know what it is for.

It's for server management...

I removed it.

Hmm, now I'm getting:

systemctl --failed
  UNIT                         LOAD      ACTIVE SUB    DESCRIPTION
● ipmievd.service              not-found failed failed ipmievd.service
● systemd-modules-load.service loaded    failed failed Load Kernel Modules

Is this progress?

I'd check it after the next boot. It's not going to try starting those services again until you reboot (or do it manually).

@derobert Hmm. How do I do it manually?

systemctl restart «service»

or service restart «service»

@derobert Ok. That got rid of the modules error.

Please VTO my question : unix.stackexchange.com/q/277927/85039

I've explained why it is on topic in the comments

Edits to the question are also coming soon

@Serg I'm not sure this question is really a good fit here. @derobert, what do you think?

@FaheemMitha why is that ?

@Serg It's clearly out of the mainstream of what most U&L people would know about.

It also asks about "System Interfaces" . UART being one of the oldest interfaces used, plus modules for it are in the kernel out of the box

I'm also having same issue when I connect my MCU to raspberry with Ubuntu Snappy which is "The underlying *nix OS on an embedded system"

I've been around on askubuntu for some time , I'm not new to stackoverflow and I'm well aware what is on-topic , what is suitable and what is not

@FaheemMitha seems fine to me

Looks to be a question about configuring the serial port

Exactly that ^ :/ Maybe I should change the title to that

I would guess it has something to do with screen. Mainly because I've never used screen's serial port support before... So I have no idea if I should be suspicious of it. But I've used minicom a ton.

@Serg there is a tradition of using the high bit (0x80) to indicate meta. E.g., 0x61 = a, 0xE1 = meta-a

meta being another name for the alt key. Or maybe the logo (Windows) key. I forget :-/

@derobert OK . . .is there a way to turn off the meta interpretation and just echo pure ascii ?

@derobert Ok. Voted to reopen. Looks like I was the last - it's open now.

I think I could try doing ^V and then pressing a . . . maybe that will disable meta interpretation

@Serg Probably. Your current title is definitely not optimal.

@FaheemMitha altered the title

@Serg No criticism intended. I just said it might not be a good fit here, not that it was off-topic.

Not a good fit means it is less likely to get answers. The more specialist a question is, the less likely it is to get an answer.

@FaheemMitha I understand. I'm just making my case clear :)

A good fraction of the questions I ask here remain unanswered, for example.

And another good fraction of them get answered by derobert. :-)

And Gilles.

In any case , I gotta run . it's 5:51 already and my friend said i should wait for her at 5:55 sharp . . . o/ Ping me if any ideas come up.

I should spend more time on U&L , I love scripting :D

Never heard of UART before. One learns something new every day.
