Issue: When I go to share my screen/tab/window on google meet, it comes up very dark.
very dark screenshot of shared screen.
Any ideas how to fix this?
Actions taken: all of the following with multiple logins/out/restarts but to no avail
You might need to update GDM3 custom configuration file
/etc/gdm3/custom.conf
Uncommenting this will force the login screen to use Xorg. #WaylandEnable=false
$ echo $XDG_SESSION_TYPE x11
Install xcompmgr using your Linux distro's package manager. sudo apt install xcompmgr After installing, open the terminal and run this command: xcompmgr -c -l0 -t0 -r0 -o.00 Open compton.conf gedit ~/.config/compton.conf Edit the following line: shadow-exclude = [ "name = 'cpt_frame_window' " ];
added google-chrome-stable --enable-features=UseOzonePlatform --ozone-platform=wayland & to ~/.local/share/applications/google-chrome.desktop

While I am trying to open my installed MySQL workbench it is not opening, I try to open using terminal it shows the below error:
command:
mysql-workbench
Error:
> Workbench can't find libproj.so, some options may be unavailable.
> /usr/bin/mysql-workbench-bin: error while loading shared libraries: libzip.so.4: cannot open shared object file: No such file
> or directory
I've tried to install broken packages and creating symbolic link but also I am not able to fix.
Can someone help to solve this issue?
Thanks in advance.
if running mysql-workbench command gives following warning:
Workbench can't find libproj.so, some options may be unavailable.
run this command to check if you have the above mentioned file :
$ find / -name libproj.so 2> /dev/null
if not found, then run this command to install the lacking file dependency to remove the warning:
$ sudo apt install libproj-dev proj-bin
It will remove the warning. Worked for me. Please try in your system. Below is my command output:
$ find / -name libproj.so 2> /dev/null
/usr/lib/x86_64-linux-gnu/libproj.so
$ mysql-workbench
Found /lib/x86_64-linux-gnu/libproj.so.15
(Note: even if this warning was there, my Workbench was still running properly. I followed the above mentioned steps just to get rid of that warning.)
Reinstalling workbench and doing --fix-broken install worked for me.
Details:
Uninstall workbench
sudo apt remove mysql-workbench
Clean
sudo apt clean
sudo apt autoremove
Update repos
sudo apt update && apt upgrade
Install workbench again
sudo apt install mysql-workbench
The fix
sudo apt --fix-broken install
Run workbench
mysql-workbench
Does anyone have any idea why the loading screen suddenly changed from this:
to this:
Also got some new backgrounds with the Debian logo like this one:
I would very much like to know what caused this and if it could have changed other system settings ( I noticed that the keyring doesn't ask me for a password anymore until I run an app on the computer and also noticed an overall slowness in running apps ). I want to point out that I didn't update nor upgraded the apt repos, I did however removed the ubuntu dock gnome shell extension and added plank, though this happened a few hours before and I rebooted twice in the meantime and the loading screen didn't change.
The second image is from Ubuntu Budgie.
How to Completely Uninstall / Remove Budgie Desktop:
To uninstall the desktop environment, open terminal and run command:
sudo apt remove budgie-desktop-environment budgie-desktop && sudo apt autoremove
And the PPA can be removed by going to System Settings -> Software & Updates -> Other Software tab.
To restore the default login screen (Unity Greeter), run command to remove GTK greeter:
sudo apt remove lightdm-gtk-greeter && sudo apt autoremove
To restore the default start-up splash logo, run command:
sudo update-alternatives --config default.plymouth
Type the number that indicates Ubuntu logo and hit enter.
Set Plymouth theme
And apply the plymouth changes via command:
sudo update-initramfs -u

I am trying to configure the networking options for my lxd container but when I try the following command:
lxc network create testbr0
I get the following result:
root#Server02:/var/lib# lxc network create testbr0
Usage: lxc [options]
Checking the list of available commands, I dont see network as an option
Here are the available commands I see:
config, copy, delete, exec, file, finger, image, info, init, launch, list, monitor, move, pause, profile, publish, remote, restart, restore, snapshot, start, stop, version
I'm using Ubuntu 14.04
Any insights?
Thanks
I assume you are using lxd Version 2.0.11. There is no network command in this version.
If you want to use the network command you have to install lxd feature releases (LXD 2.x).
On Ubuntu 14.04 there is no ppa containing the lxd feature releases, so you have to install snap and use the snap package:
sudo apt update
# check if snap is installed, install it if not
if ! type snapctl >/dev/null; then sudo apt install -y snapd; fi
# install lxd
sudo snap install lxd
# wait for lxd startup
while ! echo -e "GET / HTTP/1.0\r\n" | sudo nc -U /var/snap/lxd/common/lxd/unix.socket > /dev/null; do sleep 1; done
# migrate from ppa to snap lxd
sudo /snap/bin/lxd.migrate
# 14.04 does not add the user to lxd group so we do it explicitly
sudo adduser $(id -un) lxd
I am trying to install Couchbase sync gateway using the steps from the following URL for MacOS
https://developer.couchbase.com/documentation/mobile/current/installation/sync-gateway/index.html
This issue is, i downloaded "couchbase-sync-gateway-enterprise_1.4.1-3_x86_64.tar.gz" and its in "Downloads" folder in MacBook.
When I execute this command -> sudo tar -zxvf couchbase-sync-gateway-enterprise_1.4.1-3_x86_64.tar.gz --directory /opt
[MyMacbook:downloads administrator$ sudo tar -zxvf couchbase-sync-gateway-enterprise_1.4.1-3_x86_64.tar.gz --directory /opt
tar: could not chdir to '/opt']
Throws error as "tar: could not chdir to '/opt'"
I don't understand how to resolve this. I couldn't get help anywhere.
Please help installing Couchbase sync gateway successfully on MacBook.
It dosen't actually matter if /opt does not exist on your Mac. You can either create one before firing the command with the following command:
sudo mkdir /opt
Otherwise, you can replace "opt" with locations like : /Users/< your_user > or /usr/share or /var
I am trying to use sudo apt-get update But i am getting error as,
W: Failed to fetch http://dl.google.com/linux/chrome/deb/dists/stable/Release Unable to find expected entry 'main/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file)
E: Some index files failed to download. They have been ignored, or old ones used instead.
I tired the solution given in https://askubuntu.com/questions/120621/how-to-fix-duplicate-sources-list-entry, but again showing the same error. Suggest me something.
It looks like Google has discontinued support for i386, which is why this error now shows up. It looks like they have not gracefully for how their deb install has configured apt. To fix this run the following.
sudo sed -i -e 's/deb http/deb [arch=amd64] http/' "/etc/apt/sources.list.d/google-chrome.list"
Source: https://www.reddit.com/r/chrome/comments/48oje6/linux_how_to_fix_failed_to_fetch/
Edit: As has been pointed out by others, another command is needed to prevent this fix from reverting. Since this is at the top as the accepted answer I feel it should be part of this answer.
sudo sed -i -e 's/deb http/deb [arch=amd64] http/' "/opt/google/chrome/cron/google-chrome"
Also, this issue may exist if there are two files with name google.list and google-chrome.list in /etc/apt/sources.list.d directory with the similar entry like:
In google.list:
deb http://dl.google.com/linux/chrome/deb/ stable main
In google-chrome.list:
deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main
Then you should remove google.list file or uncomment its entry like below:
#deb http://dl.google.com/linux/chrome/deb/ stable main
That change was reverting overnight for me. Apparently you also need to change /opt/google/chrome/cron/google-chrome
sudo sed -i -e 's/deb http/deb [arch=amd64] http/' "/opt/google/chrome/cron/google-chrome"
Note: this is only for 64-bit

This doesn't work because there is a default config in /etc/default/google-chrome that contains instructions on repository updating. If you open the google-chrome.list file in /etc/apt/sources.list.d/ you will see that it has the comment:
### THIS FILE IS AUTOMATICALLY CONFIGURED ###
# You may comment out this entry, but any other modifications may be lost.
Like the note says, the changes using the instructions in the previous comments will probably be overwritten the next time you update. To resolve this, do the following:
Open a terminal and run cd /etc/default , then sudo nano google-chrome (Note: you can use whatever editor you wish of course))
In the config file, change the 2nd line: repo_reenable_on_distupgrade="true" so that it is false, as in
repo_reenable_on_distupgrade="false", then save the config file.
Now, you can make the edit to the repo as instructed above. In a terminal window run the commands as shown in the previous comments:
sudo sed -i -e 's/deb http/deb [arch=amd64] http/' "/etc/apt/sources.list.d/google-chrome.list"
sudo sed -i -e 's/deb http/deb [arch=amd64] http/' "/opt/google/chrome/cron/google-chrome"
You changes now won't be overwritten by the config directive.
PS. This works in Linux Mint 17.3 so it will probably work in Ubuntu and any Ubuntu based distro as well.
Go to "Software Sources" section in Ubuntu Settings then click on "other software" tab then uncheck: http://dl.google.com/linux/chrome/deb/stable
Now sudo apt-get update will work.
After updating manager go and undo the changes in software sources.
I solved this problem by following process:
1.Open a new Terminal window and run the following command:
sudo gedit /etc/apt/sources.list.d/google-chrome.list
2.In the text file that opens edit the file so that the line reads:
deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main
N.B: The only addition you need to make is entering the [amd64] architecture after ‘deb’ but preceding the ‘http’. Do not edit or replace any other text in this file.
3.Hit Save. Close the Gedit window and return to the Terminal and refresh your package list by runnin
sudo apt-get update
The ‘failed to fetch’ APT error should no longer appear.

This didn't work for me, until I modified yet another file:
/etc/apt/sources.list.d/additional-repositories.list
and changed:
deb http://dl.google.com/linux/chrome/deb/ stable main
to
deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main
