.I am unable to launch mysql-workbench on my Fedora 22 machine. It is installed, or at least it seems so. Help is welcome.
[root#localhost /]# dnf info mysql-community-bench
Nome : mysql-community-bench
[root#localhost /]# uname -a
Linux localhost.localdomain 4.1.3-201.fc22.i686+PAE #1 SMP Wed Jul 29 20:36:37 UTC 2015 i686 i686 i386 GNU/Linux
I don't see installed MySQL Workbench, what you installed is MySQL benchmark (not Workbench). You can grab your MySQL Workbench rpm package from https://dev.mysql.com/downloads/workbench/
What i have done to install mysql-workbench on my Fedora 22 (64 bits),
was to install required libraries before :
sudo dnf install -y ctemplate tinyxml vsqlite++ python-paramiko
Then i downloaded the mysql-workbench .rpm here : https://dev.mysql.com/downloads/workbench/
Fedora 22 (x86, 64-bit), RPM Package 6.3.4 17.4M
and finally installed successfully the package.
So maybe you could try instaling the Fedora 20 package after installing the required libraries above.

I get the error from PDO when trying to connect to PostgreSQL:
Database Connection Error: could not find driver
I ran command to install driver:
yum install php7.4-pgsql
systemctl restart httpd
Still did not work. I found another possible driver:
yum install php72w-pdo
systemctl restart httpd
Still did not work. Checking phpinfo() page does not show PDO driver for PostgreSQL installed, and checking has no output for pgsql.
php -m | grep pgsql
I also tried installing PostgreSQL on the server, but I don't think I need since the connection is remote server. I also tried other tutorials but most are for PHP 5 and not for PHP 7.4. They said use command:
yum install php-pgsql
But this command will give me error for package conflict and list of required:
Error: Package: php-pgsql-5.4.16-48.el7.x86_64 (base)
Requires: php-pdo(x86-64) = 5.4.16-48.el7
Installed: php-pdo-7.4.11-1.el7.remi.x86_64 (#remi-php74)
php-pdo(x86-64) = 7.4.11-1.el7.remi
Available: php-pdo-5.4.16-48.el7.x86_64 (base)
php-pdo(x86-64) = 5.4.16-48.el7
...
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
However, I don't think these options should be necessary for Centos 7.4, PHP 7.4.
I can connect from MacOs development environment, but not from the Centos server.
What should I do to install the driver for PDO PostgreSQL?
Turns out I had multiple versions of PHP enabled.
Here is solution to disable all except for the one you want:
php -v
PHP 7.4.24 (cli) (built: Sep 21 2021 11:23:11) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
Check which version you are running (example 7.4)
yum-config-manager --disable 'remi-php*'
yum-config-manager --enable remi-php74
Then install is easy:
yum install php-pdo_pgsql
systemctl restart httpd
When I upgraded fedora from 31 to 33, I found out that the base python package had been upgraded from 3.7.9 to 3.9, and that python references in virtual environment folders were now pointing to the new version of python.
There were no problems activating my python 3.7 virtual environment
[bou#bous-fed33 avguide]$ source ~/py37/bin/activate
(py37) [bou#bous-fed33 avguide]$ which python
~/py37/bin/python
However the python version was no longer 3.7.9 but 3.9, which came with fedora 33
(py37) [bou#bous-fed33 avguide]$ python -V
Python 3.9.0
Now when I tried running jupyter notebook get errors ModuleNotFoundError
(py37) [bou#bous-fed33 avguide]$ jupyter notebook --port 7777
[W 09:14:02.710 NotebookApp] Error loading server extension jupyterlab
ModuleNotFoundError: No module named 'jupyterlab'
Also get errors for other packages like pandas, numpy etc which had all been fine before.
(py37) [bou#bous-fed33 avguide]$ python
Python 3.9.0 (default, Oct 6 2020, 00:00:00)
[GCC 10.2.1 20200826 (Red Hat 10.2.1-3)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas as ps
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'pandas'
I had tried to reinstall all the packages from existing requirements.txt file and manual reinstalls as well - all failed with errors. There was also no point in reinstalling python 3.7 as it was still there.
(py37) [bou#bous-fed33 avguide]$ pip3 install --force-reinstall -r requirements.txt
[bou#bous-fed33 avguide]$ sudo dnf install python37
Package python3.7-3.7.9-2.fc33.x86_64 is already installed.
I found a relatively simple FIX after a while.
The way python versions is managed is by using symbolic links in virtual env folders. So all we have to do is find the location of existing python binary for 3.7.9 or whatever python version your virtual environment uses and update the symbolic links to point to the correct python base packages.
These are the python versions installed in my fedora OS/base.
[bou#bous-fed33 ~]$ ls -ltr /usr/bin/python3*
-rwxr-xr-x. 2 root root 15536 Sep 22 19:23 /usr/bin/python3.7
-rwxr-xr-x. 1 root root 15536 Sep 25 23:37 /usr/bin/python3.8
lrwxrwxrwx. 1 root root 9 Oct 7 00:19 /usr/bin/python3 -> python3.9 <<<
-rwxr-xr-x. 1 root root 15536 Oct 7 00:20 /usr/bin/python3.9 <<<
Note how /usr/bin/python3 points to python3.9
Locate the symbolic links in virtual environment ~/py37/bin/ folder
[bou#bous-fed33 avguide]$ cd ~/py37/bin/
[bou#bous-fed33 bin]$ ls -ltr python*
lrwxrwxrwx. 1 bou bou 16 Dec 29 2019 python3 -> /usr/bin/python3
lrwxrwxrwx. 1 bou bou 7 Dec 29 2019 python -> python3
Note how python points to python3 and python3 in turn points to operating system package /usr/bin/python3 - which after the fedora python upgrade no longer points to /usr/bin/python3.7 but to the new version of python /usr/bin/python3.9
So all we need to do is remove existing softlinks
[bou#bous-fed33 bin]$ rm python3 python
And then create new files or symbolic links python3 and python that point to python3.7 binary in /usr/bin/python3.7
[bou#bous-fed33 bin]$ ln -s /usr/bin/python3.7 python3
[bou#bous-fed33 bin]$ ln -s python3 python
Activate virtual environment and check python version is correct.
[bou#bous-fed33 bin]$ ls -ltr python*
lrwxrwxrwx. 1 bou bou 18 Dec 2 10:03 python3 -> /usr/bin/python3.7
lrwxrwxrwx. 1 bou bou 7 Dec 2 10:04 python -> python3
[bou#bous-fed33 avguide]$ source ~/py37/bin/activate
(py37) [bou#bous-fed33 avguide]$ python -V
Python 3.7.9
(py37) [bou#bous-fed33 avguide]$ which python
~/py37/bin/python
(py37) [bou#bous-fed33 avguide]$ python
Python 3.7.9 (default, Sep 22 2020, 09:19:36)
[GCC 10.2.1 20200826 (Red Hat 10.2.1-3)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas as pd
>>> quit()
We got the correct python version back for our virtual env and JupyterLab runs all right as well now.
(py37) [bou#bous-fed33 avguide]$ jupyter notebook --port 7777
[I 10:07:54.408 NotebookApp] JupyterLab extension loaded from /home/bou/py37/lib64/python3.7/site-packages/jupyterlab
[I 10:07:54.408 NotebookApp] JupyterLab application directory is /home/bou/py37/share/jupyter/lab
[I 10:07:54.410 NotebookApp] The Jupyter Notebook is running at:
[I 10:07:54.410 NotebookApp] https://bous-fed33:7777/
Hope this helps out someone running into similar problems with using their python virtual environment after base OS and/or python upgrade to a new version.
A better solution is to use pyenv, as it is specifically designed for this situation.
Pyenv will be available in your package repo... so yum search pyenv, then install.
See all available Python versions that pyenv can install for you:
$ pyenv install --list
Then pick form the list, eg. you'll see your missing Python 3.7.9. Install it to your local pyenv store, which will allow you to use it in your virtual environment:
$ pyenv install 3.7.9
You can then activate it in the directory containing your virtual env:
$ cd avguide
$ python --version
Python 3.9.0
$ pyenv local 3.7.9
$ python --version
Python 3.7.9
and it will automatically take care of you python binary links. See this tutorial and search for similar ones to get all the details.
Summary
I try to install MYSQL community edition 8.0 on my Amazon Linux server
Command i have done so far
cd /home/ec2-user
wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.16-2.el7.x86_64.rpm-bundle.tar
tar -xvf mysql-8.0.16-2.el7.x86_64.rpm-bundle.tar
rpm -ivh mysql-community-server-8.0.16-2.el7.x86_64.rpm
I get the following error :
error: Failed dependencies:
libsasl2.so.3()(64bit) is needed by mysql-community-server-8.0.16-2.el7.x86_64
systemd is needed by mysql-community-server-8.0.16-2.el7.x86_64
What i tried by now
The library libsasl2.so.3()(64bit) is included in cyrus-sasl-lib
I tried to install it but still the same result
Here is the command i tried : sudo yum install cyrus-sasl-lib
Operating System
Linux ip-172-31-86-163 4.14.146-93.123.amzn1.x86_64 #1 SMP Tue Sep 24 00:45:23 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
Expected Result :
Success
Error Message i have :
Failed dependencies:
libsasl2.so.3()(64bit) is needed by mysql-community-server-8.0.16-2.el7.x86_64
try
yum install /path/to/mysql-8...rpm
then yum will try to find the dependencies you need. If some dependencies cannot be found, you can try downloading them yourself, or enabling repositories. But be careful since you are trying to install recent software on an old os... I don't know if amazon has centos8 machines already, otherwise that would probably help you out :)
Can anybody tell me the procedure for installing iCub (humanoid) simulator on Linux mint 17 operating system. It seems they have only got the instruction procedure for Linux version of Debian and Ubuntu on their website.
Thanks
Lekan
Linux Mint 17 is derived from Ubuntu 14.04. So you can use the same installation procedure for the Ubuntu to Linux Mint. Steps for the same are given below.
Open terminal and enter the following command.
sudo sh -c 'echo "deb http://www.icub.org/ubuntu trusty contrib/science" > /etc/apt/sources.list.d/icub.list'
sudo apt-get update
sudo apt-get install icub
For more information follow the link iCub Installation procedure for Linux
I have following packages installed on my Scientific Linux release 6.0 (Carbon):
eclipse-svnkit-1.3.0-3.el6.x86_64
eclipse-rcp-3.6.1-6.13.el6.x86_64
eclipse-swt-3.6.1-6.13.el6.x86_64
eclipse-platform-3.6.1-6.13.el6.x86_64
eclipse-subclipse-1.6.5-6.el6.x86_64
eclipse-phpeclipse-1.2.1-6.el6.noarch
svnkit-1.3.0-3.el6.x86_64
Everything was working fine uppon installation, I haven't used my Eclipse in a while and now when I tried using I'm missing Subversion part (subclipse). I've tried removing and reinstalling all of these packages but that didn't help me solve my problem, so I'm kind of lost at this point... any ideas?
here is few more related packages that I have installed:
[alexus#wcmisdlin02 ~]$ sudo grep javahl /var/log/yum.log
May 14 14:01:38 Installed: subversion-javahl-1.6.11-2.el6_0.3.x86_64
Jun 09 09:57:50 Updated: subversion-javahl-1.6.11-2.el6_1.4.x86_64
[alexus#wcmisdlin02 ~]$ rpm -qa | grep ^subversion
subversion-1.6.11-2.el6_1.4.x86_64
subversion-javahl-1.6.11-2.el6_1.4.x86_64
[alexus#wcmisdlin02 ~]$
Whenever I try to do File-New I only get "General" and "CVS" (I think you get them when installing regular eclipse, I dont get PHP or SVN)
run as root
$ su -
# eclipse -clean
