Adept gives a message that the packaging database is locked by another program

Try

1. sudo dpkg --configure -a

else

2. ps -ewf| grep adept|grep -v grep|awk '{print $2}'

This will list all process being used by adept, one per line. Next kill these processes:

sudo kill -9

else Use this command....

3. $ sudo fuser -vki /var/lib/dpkg/lock

This will ask you if you want to kill the process using the file. Now you can run:

$ sudo dpkg --configure -a

to make sure all packages are fully installed.
