+[Solved] “sub process usr bin dpkg returned an error code 1″ Error in Ubuntu
+======
+If you are encountering “sub process usr bin dpkg returned an error code 1” while installing software on Ubuntu Linux, here is how you can fix it.
+
+One of the common issue in Ubuntu and other Debian based distribution is the broken packages. You try to update the system or install a new package and you encounter an error like ‘Sub-process /usr/bin/dpkg returned an error code’.
+
+That’s what happened to me the other day. I was trying to install a radio application in Ubuntu when it threw me this error:
+```
+Unpacking python-gst-1.0 (1.6.2-1build1) ...
+Selecting previously unselected package radiotray.
+Preparing to unpack .../radiotray_0.7.3-5ubuntu1_all.deb ...

+Errors were encountered while processing:
+polar-bookshelf
+E: Sub-process /usr/bin/dpkg returned an error code (1)
+
+```
+
+The last three lines are of the utmost importance here.
+```
+Errors were encountered while processing:
+polar-bookshelf
+E: Sub-process /usr/bin/dpkg returned an error code (1)
+
+```
+
+It tells me that the package polar-bookshelf is causing and issue. This might be crucial to how you fix this error here.
+
+### Fixing Sub-process /usr/bin/dpkg returned an error code (1)
+
+![Fix update errors in Ubuntu Linux][1]
+
+Let’s try to fix this broken error package. I’ll show several methods that you can try one by one. The initial ones are easy to use and simply no-brainers.
+
+You should try to run sudo apt update and then try to install a new package or upgrade after trying each of the methods discussed here.
+
+#### Method 1: Reconfigure Package Database
+
+The first method you can try is to reconfigure the package database. Probably the database got corrupted while installing a package. Reconfiguring often fixes the problem.
+```
+sudo dpkg --configure -a
+
+```
+
+#### Method 2: Use force install
+
+If a package installation was interrupted previously, you may try to do a force install.
+```
+sudo apt-get install -f
+
+```
+
+#### Method 3: Try removing the troublesome package
+
+If it’s not an issue for you, you may try to remove the package manually. Please don’t do it for Linux Kernels (packages starting with linux-).
+```
+sudo apt remove
+
+```
+
+#### Method 4: Remove post info files of the troublesome package
+
+This should be your last resort. You can try removing the files associated to the package in question from /var/lib/dpkg/info.
+
+**You need to know a little about basic Linux commands to figure out what’s happening and how can you use the same with your problem.**
+
+In my case, I had an issue with polar-bookshelf. So I looked for the files associated with it:
+```
+ls -l /var/lib/dpkg/info | grep -i polar-bookshelf
+-rw-r--r-- 1 root root 2324811 Aug 14 19:29 polar-bookshelf.list
+-rw-r--r-- 1 root root 2822824 Aug 10 04:28 polar-bookshelf.md5sums
+-rwxr-xr-x 1 root root 113 Aug 10 04:28 polar-bookshelf.postinst
+-rwxr-xr-x 1 root root 84 Aug 10 04:28 polar-bookshelf.postrm
+
+```
+
+Now all I needed to do was to remove these files:
+```
+sudo mv /var/lib/dpkg/info/polar-bookshelf.* /tmp
+
+```
+
+Use the sudo apt update and then you should be able to install software as usual.
+
+#### Which method worked for you (if it worked)?
