I can't seem to add any applications. I receive a notice saying "Waiting for package manager lock". I like Elementary but I am stuck and unable to install any additional programs. Should I do a clean install of Elementary....ie start again from scratch?
Had same problem - in the end fixed using
sudo dpkg --configure -a from a hint provided when trying
sudo apt-get update.
That's probably because some other program is using apt or you aren't running it with sudo. Just reboot and then do
sudo apt install [program]
I successfully used
sudo dpkg --configure -a once a couple of days ago and it worked, but tonight I can't get anything to work.
When I try
sudo dpkg --configure -a I get this:
dpkg: error: dpkg status database is locked by another process
When I try
/etc/apt/sources.list I get
bash: /etc/apt/sources.list: Permission denied
I'm curious; why is permission to display a list of PPAs denied the administrator?
At https://askubuntu.com/questions/13965/waiting-for-other-software-manager-to-quit it says to check in System Monitor for a process that looks like an apt or an apt-get or a synaptic process and kill it. I can't see any.
That page also suggests trying
sudo rm /var/lib/dpkg/lock and it didn't give me an error message but there was no indication that it did anything and I still can't update.
I have shut the computer down two or three times to no avail.
Sorry I can't highlight the commands like you guys have. I looked at the advanced help and couldn't see how to do it.
Edit: I just tried to update from the terminal using
sudo apt-get update and this is what I got (I took the http: out of the first nine lines because I had too many links):

There is a process called dconf-service. Should I end or kill it?
I can't believe it! I decided to shut things down and go to bed, so I clicked to close the Terminal and it said that there was a process running in the Terminal and, of course, it would quit if I closed. I closed and then tried updating and the system and Firefox both updated.
I started using the Terminal because I couldn't update and I had quit Terminal several times during this process, but this time it was different.
I wish I knew why.
I still can't display the list of PPAs. That's weird.
In case of worst case scenario, which is not the case in this posting, if you would ever consider a re-install, I made things really easy for you: http://www.leeuwtje-productions.me/en/
Just install a fresh Eos system, download the tool and install a complete elementary system set of software automatically!
