Bench update : Some Library issues

Install / Update

Hello Community,

Somehow my system gives me an error while I am executing the bench update command.

Here are the details of my error:

Traceback (most recent call last):

I have manually tried to execute this requirement.txt file of frappe.

Updating ./src/mysqlclient clone (to 1.3.12)
Complete output from command python setup.py egg_info:
sh: 1: mysql_config: not found
Traceback (most recent call last):
File “”, line 1, in

libs = mysql_config(“libs_r”)
File “setup_posix.py”, line 26, in mysql_config
raise EnvironmentError(“%s not found” % (mysql_config.path,))
EnvironmentError: mysql_config not found

Finally, I found that some libraries which are missing in my system. One of them is libmysqlclient-dev

When I am installing this library into my system, immediately system gives me an error. The error is:

The following packages have unmet dependencies:
libmysqlclient-dev : Depends: libmysqlclient18 (= 5.5.58-0ubuntu0.14.04.1) but 10.1.29+maria-1~trusty is to be installed
E: Unable to correct problems, you have held broken packages.

I think this is the main error and others are related to this error.

So I am looking for the solution to this error.

Please give me the direction to solve this error.

Thank you.

sudo apt-get install libmysqlclient-dev
will update that dependancy
After that, you should probably do
sudo apt-get update
to make sure your system is up to date on all libs etc

But not even I am able to complete the first step sudo apt-get install libmysqlclient-dev.

Error:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

Try clearing the cache…
sudo apt-get clean
and then retry the other commands

5

I already did. Still the same issue.

6

Let’s just check what is “holding”…
sudo dpkg --get-selections | grep hold
once you know what the problem package is, use
sudo apt-get remove problem-package

sudo apt-mark unhold problem-package will release them as well

or try
sudo apt-get autoremove

7

I tried this command just before 10 seconds but I don’t get any holding package currently.

8

add a --purge flag
sudo apt-get remove --purge .....
or use the auto remove
sudo apt-get autoremove

9

What should I enter in the package name?
–purge … ?

10

look like the culprits to me. Maybe get a list of all your mysql packages to see what’s installed

11

Ok, I will try to remove all my mysql packages.

Thanks.
