Two things to check (assuming your machine is called my-machine, you can change this as appropriate): That the /etc/hostname file contains just the name of the machine. That /etc/hosts has an entry for localhost. It should have something like: 127.0.0.1 localhost.localdomain localhost 127.0.1.1 my-machine If either of these files aren't ...

What's whoopsie ? It's the "Ubuntu Error Reporting" daemon, and is installed by default in both desktop/server installations. When something crashes, whoopsie does two things: Collects the crash report generated by Apport and Can send them to Ubuntu/Canonical (specifically to https://daisy.ubuntu.com :) Whoopsie won't send your crash reports without ...

Edit your /etc/sysctl.conf file with your favourite text editor, e.g. nano: sudo nano /etc/sysctl.conf and append (or modify the value of) fs.inotify.max_user_watches=100000 at the end of the file as a new line.

Edit /etc/hosts and append your new hostname to the 127.0.0.1 line (or create a new line if you prefer that).

The following answer by rubo77 here fixed it for me: Ubuntu has an error reporting system called apport which tries to catch all program crashes in the background and report them to help the developers. It seems that after a dist-upgrade there are stuck some reports that are tried to resubmitted somehow, but disabling apport is not a desirable solution. ...

Whoopsie is part of the Ubuntu error tracker. It takes the crash reports that apport creates and presents whenever an application fails and sends them to a Canonical server for further processing. The data collected from these reports help us prioritize and track the most pressing issues: http://errors.ubuntu.com The small whoopsie daemon process is run by ...

Note, this is an answer to this question which has been merged with this one. Your hostname (dave00-G31M-ES2L) is not represented in /etc/hosts. Add an L to this line: 127.0.1.1 dave00-G31M-ES2 So it becomes: 127.0.1.1 dave00-G31M-ES2L In order to accomplish this, open a console (press Ctrl+Alt+T) and type: sudo gedit /etc/hosts Add the letter ...

This is my "linux emergency cheat sheet": 1. Non responsive application SUPER --> type in System Monitor --> RETURN --> find process --> right click --> Kill Process or ALT + F2 --> type in xkill --> x marks the spot (or in this case frozen app) or CTRL + ALT + T --> type in top --> find process ID --> k PID where PID = process ID Effect: This kills ...

Editing /proc/sys/fs/inotify/max_user_watches directly results in Fsync errors in GVIM. This is because you can't really modify those files directly. Instead, it is better to use this command: sudo sysctl -w fs.inotify.max_user_watches=100000 This doesn't cause file editing problems, and to me, looks like a more proper method.

According to the bug report at https://github.com/clementine-player/clementine/issues/3593 a workaround is to uncheck Save statistics in file tags when possible.

The problem is that you have Unicode quotation marks instead of ASCII quotation marks; probably your editor automatically changed them, or you copied the text from a site that does this automatically in its authoring software. Replace the quotes with normal ASCII quote (0x22, ") and it should work. Fixed source: #include <stdio.h> int main() { ...

I was having the same issue even though the hostname in my /etc/hostname file and /etc/hosts file matched. My hostname was "staging_1". It turns out that you can't have an underscore in your hostname, which is why I was getting this error. Changing the underscore to a hyphen fixed my problem.
