Could not get lock /var/lib/dpkg/lock

Today, I tried to install Git on my Ubuntu machine and during that I received following exception related to locking. In my this post, I have shared all commands and error messages with you.


Command
sudo apt-get install git

Error Message
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?



After searching above message, I found a command

sudo lsof /var/lib/dpkg/lock

after pressing ENTER, it might asked you for password. Type the password and in result you might get following output

lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
      Output information may be incomplete.
COMMAND    PID USER   FD   TYPE DEVICE SIZE/OFF   NODE NAME
unattende        1468 root    5uW  REG    8,1        0 154817 /var/lib/dpkg/lock

Type following command to kill the session with provided PID by your system. In my case PID # was 1468. I use following command to kill this process id.

sudo kill 1468

After execution of above statement, now I was able to download GIT by using following command again which I executed in start.

sudo apt-get install git

ORA-38104: Columns referenced in the ON Clause cannot be updated

In my case, this error pertains to Oracle Merge query. After 30 minutes of time wastage and a lot of hunting on different forums, I come to know that where and why was my merge query throwing exception.

I was giving multiple criteria in ON clause of merge query, and was also trying to update a column which I have mentioned in ON clause. Once I remove that column from update clause of merge query, it executed successfully.

I hope that this will also works for you.
