To solve this error, download AccessDatabaseEngine.exe from this Microsoft website.
Recently, I have a problem where when I tried to update Ubuntu package via apt-get, it shows HTTP 401 proxy error related.
Just a note, I’m running VM using my office network which has an enterprise web proxy servers.
From this site;
APT configuration file method
This method uses the apt.conf file which is found in your /etc/apt/ directory. This method is useful if you only want apt-get (and not other applications) to use a http-proxy permanently.
On some installations there will be no apt-conf file set up. This procedure will either edit an existing apt-conf file or create a new apt-conf file.
gksudo gedit /etc/apt/apt.conf
Add this line to your /etc/apt/apt.conf file (substitute your details for yourproxyaddress and proxyport).
Save the apt.conf file.
One day, I open my email via mail command and see bunch of error mail received by me, written something like this:
PHP message: WordPress database error Table 'blog.wp_termmeta' doesn't exist for query SELECT term_id, meta_key, meta_value FROM wp_termmeta WHERE term_id IN (108) ORDER BY meta_id ASC made by require('wp-blog-header.php'), wp, WP->main, do_action_ref_array, call_user_func_array, Jetpack_RelatedPosts->action_frontend_init, Jetpack_RelatedPosts->_action_frontend_init_ajax, Jetpack_RelatedPosts->get_for_post_id, Jetpack_RelatedPosts->_get_related_posts, Jetpack_RelatedPosts->_get_related_post_data_for_post, Jetpack_RelatedPosts->_generate_related_post_context, get_the_category, get_the_terms, wp_get_object_terms, update_termmeta_cache, update_meta_cache
Upon diving in Google ocean, I found this solution that may solve the problem:
CREATE TABLE `wp_termmeta` ( `meta_id` bigint(20) unsigned NOT NULL AUTO_INCREMENT, `term_id` bigint(20) unsigned NOT NULL DEFAULT '0', `meta_key` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL, `meta_value` longtext COLLATE utf8mb4_unicode_ci, PRIMARY KEY (`meta_id`), KEY `term_id` (`term_id`), KEY `meta_key` (`meta_key`(191)) ) ENGINE=InnoDB AUTO_INCREMENT=3255 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
Use this SQL query to manually add the wp_termmeta table into your WordPress database; if the wp_termmeta table doesn’t exist in your DB.
There’s one time I encountered this error when executing a bash code/script:
install.sh: Syntax error: "(" unexpected
The script does not begin with a shebang line, so the kernel executes it with /bin/sh. On Ubuntu, /bin/sh is dash, a shell designed for fast startup and execution with only standard features. When dash reaches the line, it sees a syntax error: that parenthesis doesn’t mean anything to it in context.
Since dash (like all other shells) is an interpreter, it won’t complain until the execution reaches the problematic line. So even if the script successfully started at some point in your testing, it would have aborted once the problematic line was reached.
The shebang line must be the very first thing in the file. Since you use bash features, the first line of the file must be #!/bin/bash or #!/usr/bin/env bash.
There is one time I see this kind of error:
InsecurePlatformWarning: A true SSLContext object is not available.
This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail.
For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
If you’re on Ubuntu, you may run into trouble installing pyopenssl, so you’ll need these dependencies:
apt-get install libffi-dev libssl-dev
Then you’ll only need to install the security package extras:
pip install requests[security]
or, install them directly via pip:
pip install pyopenssl ndg-httpsclient pyasn1
Requests package/library will then automatically inject pyopenssl into urllib3
There is one time I tried to install some python package via pip install requirement. But I encountered some error like this:
from pkg_resources import load_entry_point
ImportError: No module named pkg_resources
To fix the issue, run the setup script for setuptools:
wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | python
Yeah. it solve my problem. Probably. XD
Recently, I saw this kind or error quite frequent. At first I thought that it was nothing.
But eventually, it’s kinda bothering me when I see the error message :p
Jul 6 15:18:01 lel CRON: pam_env(cron:session): Unable to open env file: /etc/default/locale: No such file or directory
Jul 6 15:31:50 lel sshd: pam_env(sshd:session): Unable to open env file: /etc/default/locale: No such file or directory
So, here is the solution to solve this problem.
First, run this command:
sudo update-locale LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8
It updates /etc/default/locale with provided values.
If you see the /etc/default/locale file, it shows something like this:
# File generated by update-locale
If the problem still occur, maybe you can try this first before running the command above again:
sudo locale-gen en_US.UTF-8 sudo dpkg-reconfigure locales
If you encounter error something like this:
Cannot find module (SNMPv2-MIB): At line 0 in (none)
Cannot find module (SNMPv2-SMI): At line 0 in (none)
Cannot find module (SNMP-NOTIFICATION-MIB): At line 0 in (none)
Cannot find module (SNMPv2-TM): At line 0 in (none)
Then, where are in the same path. Path where we searching for the answers. XD
So, here is the solution to solve this error.
First, edit this sources.list file:
sudo vi /etc/apt/sources.list
add this line to the end of file:
deb http://fr.archive.ubuntu.com/ubuntu precise main multiverse
:w to save and :q to exit vi editor
Then, install this packages:
sudo apt-get install snmpd snmp-mibs-downloader
And then run this:
Voila! Done. Hope it helps. 🙂
Recently, I forgot my “root” password for my Ubuntu (duh!). So I try attempting to change my “root” password by selecting recovery mode on the grub menu and dropped into a root shell prompt.
Everything works perfect until I try to change the password. The picture above is what I get when i try to change the password. 🙁
So, to solve this, just run this on the prompt:
mount -rw -o remount /
Anddddd… Walla! Try to reset the password again and it works! 🙂
I think most of you will encounter with this kind of problem if you are using the previous version of Ubuntu.
W: Failed to fetch gzip:/var/lib/apt/lists/partial/us.archive.ubuntu.com_ubuntu_dists_natty_main_source_Sources Hash Sum mismatch,
E: Some index files failed to download. They have been ignored, or old ones used instead.
The solution is to remove the content of
sudo rm /var/lib/apt/lists/*
sudo apt-get update
