In case somehow, you got duplicate mails in a maildir, like me, maybe this is helpful to you:
?
1

find /var/mail/user -type d -name cur -print0 | xargs -0 /usr/bin/fdupes -n | less

Of course you need fdupes installed. On debian:
?
1

apt-get install fdupes

The above command is the dry run, showing you the duplicates.

Then to delete the duplicates, leaving only the first found file:
?
1

find /var/mail/user -type d -name cur -print0 | xargs -0 /usr/bin/fdupes -ndN | less

Use the same thing again with “new” instead of “cur” if you have duplicate unread mails. This only looks at duplicates within the same folder, so you can also safely run it on /var/mail for all users.

Vérif CSR :
openssl req -in mycsr.csr -noout -text

Commande rpm intéressante :

rpm -q --changelog sudo

Si datapump en erreur => CTRL-C

stop_job=immediate # peut être long, à tester sans le "immediate"

Faire les alter nécessaires.

Pour reprendre, vérifier les jobs datapump :
SELECT owner_name, job_name, operation, job_mode, state FROM dba_datapump_jobs;

Puis lancer le datapump :

impdp attach=SYS_IMPORT_FULL_01 # job_name

Dans datapump, si job_mode est "NOT RUNNING" :
start_job # ajouter =SKIP_CURRENT si c'est vraiment nécessaire.

Puis, pour faire l'équivalent d'un "fg" :
continue_client

To fix this, I found the following steps worked:
sudo apt-get install --reinstall ca-certificates
to ensure you have the latest certificates by your distribution – this might help you, but it didn’t assist me 🙁

So I downloaded the Let’s Encrypt root certificates and forced a rebuild of the certificate store:

sudo curl https://letsencrypt.org/certs/isrgrootx1.pem.txt -o /usr/local/share/ca-certificates/isrgrootx1.crt
sudo curl https://letsencrypt.org/certs/letsencryptauthorityx1.pem.txt -o /usr/local/share/ca-certificates/letsencryptauthorityx1.crt
sudo curl https://letsencrypt.org/certs/letsencryptauthorityx2.pem.txt -o /usr/local/share/ca-certificates/letsencryptauthorityx2.crt
sudo curl https://letsencrypt.org/certs/lets-encrypt-x1-cross-signed.pem.txt -o /usr/local/share/ca-certificates/letsencryptx1.crt
sudo curl https://letsencrypt.org/certs/lets-encrypt-x2-cross-signed.pem.txt -o /usr/local/share/ca-certificates/letsencryptx2.crt
sudo curl https://letsencrypt.org/certs/lets-encrypt-x3-cross-signed.pem.txt -o /usr/local/share/ca-certificates/letsencryptx3.crt
sudo curl https://letsencrypt.org/certs/lets-encrypt-x4-cross-signed.pem.txt -o /usr/local/share/ca-certificates/letsencryptx4.crt
sudo dpkg-reconfigure ca-certificates

and everything worked!

If you are running Java, you may need to also add the certificates to the Java Keytool:
keytool -trustcacerts -keystore $JAVA_HOME/jre/lib/security/cacerts -storepass changeit -noprompt -importcert -file /usr/local/share/ca-certificates/isrgrootx1.crt
keytool -trustcacerts -keystore $JAVA_HOME/jre/lib/security/cacerts -storepass changeit -noprompt -importcert -file /usr/local/share/ca-certificates/letsencryptauthorityx1.crt
(change the storepass password [default of “changeme”] to whatever is relevant to you)

Typing vagrant from the command line will display a list of all available commands.

Be sure that you are in the same directory as the Vagrantfile when running these commands!
Creating a VM

vagrant init -- Initialize Vagrant with a Vagrantfile and ./.vagrant directory, using no specified base image. Before you can do vagrant up, you'll need to specify a base image in the Vagrantfile.
vagrant init <boxpath> -- Initialize Vagrant with a specific box. To find a box, go to the public Vagrant box catalog. When you find one you like, just replace it's name with boxpath. For example, vagrant init ubuntu/trusty64.

Starting a VM

vagrant up -- starts vagrant environment (also provisions only on the FIRST vagrant up)
vagrant resume -- resume a suspended machine (vagrant up works just fine for this as well)
vagrant provision -- forces reprovisioning of the vagrant machine
vagrant reload -- restarts vagrant machine, loads new Vagrantfile configuration
vagrant reload --provision -- restart the virtual machine and force provisioning

Getting into a VM

vagrant ssh -- connects to machine via SSH
vagrant ssh <boxname> -- If you give your box a name in your Vagrantfile, you can ssh into it with boxname. Works from any directory.

Stopping a VM

vagrant halt -- stops the vagrant machine
vagrant suspend -- suspends a virtual machine (remembers state)

Cleaning Up a VM

vagrant destroy -- stops and deletes all traces of the vagrant machine
vagrant destroy -f -- same as above, without confirmation

Boxes

vagrant box list -- see a list of all installed boxes on your computer
vagrant box add <name> <url> -- download a box image to your computer
vagrant box outdated -- check for updates vagrant box update
vagrant boxes remove <name> -- deletes a box from the machine
vagrant package -- packages a running virtualbox env in a reusable box

Saving Progress

-vagrant snapshot save [options] [vm-name] <name> -- vm-name is often default. Allows us to save so that we can rollback at a later time
Tips

vagrant -v -- get the vagrant version
vagrant status -- outputs status of the vagrant machine
vagrant global-status -- outputs status of all vagrant machines
vagrant global-status --prune -- same as above, but prunes invalid entries
vagrant provision --debug -- use the debug flag to increase the verbosity of the output
vagrant push -- yes, vagrant can be configured to deploy code!
vagrant up --provision | tee provision.log -- Runs vagrant up, forces provisioning and logs all output to a file

Plugins

vagrant-hostsupdater : $ vagrant plugin install vagrant-hostsupdater to update your /etc/hosts file automatically each time you start/stop your vagrant box.
