Last month downloaded mongoDB onto my Ubuntu 20.04 using sudo apt install mongodb-org I found the package, installed it and mongodb was working fine. I however deleted it and when I try reinstalling it the same command outputs "Cannot locate file mongodb-org". sudo apt install mongodb works but sudo systemctl start mongod.service outputs "Failed to start mongod.service: Unit mongod.service not found". How do I solve this? I once set my ubuntu software to download from Main server, but it was originally downloading from my local home country server, which I changed the setting back to. Could this be an issue?

Not much time after I installed my ubuntu, I installed ubuntu tweak and added shortcut keys for the applications I used most.

My Ubuntu tweak's shortcut management screen

However, I wanted to remove a shortcut key and was not able to (the last one). At least, I couldn't figure out a way to do that. I want to reconfigure them using ubuntu's keyboard tool, so I don't mind if I have to delete all shortcut keys from ubuntu tweak. Does anyone know how to do that?

Ubuntu-Tweak doesn't have the option Startup which includes

  • Session Manager
  • Session Control and few other options are not there. I am running the latest version available to download. I remember having all those menus in lucid.

for a better difference comparison see the menus in the ubuntu tweak homepage http://ubuntu-tweak.com/ with mine....

alt text

how can I get these option back.

here is the error I get when I run Ubuntu Tweak from terminal

ERROR:dbus.proxies:Introspect error on :1.142:/com/ubuntu_tweak/daemon: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 1 matched rules; type="method_call", sender=":1.141" (uid=1000 pid=16550 comm="/usr/bin/python) interface="org.freedesktop.DBus.Introspectable" member="Introspect" error name="(unset)" requested_reply=0 destination=":1.142" (uid=0 pid=16560 comm="/usr/bin/python))

Update: I installed the same deb on another computer and that has nothing wrong. all the menus are listed fine.
