I went to [https://certbot.eff.org/#debianjessie-apache](https://certbot.eff.org/#debianjessie-apache) and read the install command “sudo apt-get install python-letsencrypt-apache -t jessie-backports”. After i run this command it results in an error: root@server1:~# apt-get install python-letsencrypt-apache -t jessie-backports Pakketlijsten worden ingelezen… Klaar E: Een waarde ‘jessie-backports’ voor APT::Default-Release is ongeldig, aangezien een dergelijke uitgave niet voorkomt in de bronnen This dutch and means: Package lists are read … done A value ‘Jessie-backports’ for APT::Default-Release is not valid, since such an issue is not present in the sources. What can I do to successfully install certbot with apt-get on my Debian 8.4 (Jessie) with Apache 2.4. ---

Oh yes ofcourse thank you. I never used backports before. Oke wen i create the /etc/apt/sources.list.d/backports.list and run apt-get update i tried the certbot install command again this time again a error: > _Sommige pakketten konden niet geïnstalleerd worden. Dit kan betekenen_ > _dat u om een onmogelijke situatie gevraagd heeft, of, indien u_ > _de distributie 'unstable' gebruikt, dat sommige benodigde pakketten nog gemaakt moeten worden of uit 'Incoming' verwijderd werden._ > _De volgende informatie kan misschien helpen de situatie op te lossen:_ > _De volgende pakketten hebben niet-voldane vereisten:_ > \_ python-letsencrypt-apache : Vereisten: letsencrypt (\>= 0.5.0~) maar het zal niet geïnstalleerd worden\_ > \_ Vereisten: python-letsencrypt maar het zal niet geïnstalleerd worden\_ > _E: Kan problemen niet verhelpen, u houdt defecte pakketten vast._ This is again in dutch below the google translation: > _Some packages could not be installed.

I see this error as well. It seems the python-letsencrypt has gone missing from the backports repository. apt-get install letsencrypt -t jessie-backports Reading package lists… Done Building dependency tree Reading state information… Done 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 or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: letsencrypt : Depends: python-letsencrypt (= 0.5.0-1~bpo8+1) but it is not going to be installed E: Unable to correct problems, you have held broken packages. ---

Same problem here but: > python-letsencrypt: > Installed: (none) > Candidate: 0.5.0-1~bpo8+1 > Version table: > 0.5.0-1~bpo8+1 0 > 100 [Index of /debian/](http://ftp.fr.debian.org/debian/) jessie-backports/main amd64 Packages > is available, in the right version, i check for all the dependencies and all of theme are present, in the right version... edit: Strange, i edit my source.list to set an official repo (from [ftp.debian.org](http://ftp.debian.org) to [ftp.fr.debian.org](http://ftp.fr.debian.org)). Then apt-get install letsencrypt -t jessie-backports always give me an error but when i type > apt-get install -t jessie-backports certbot everything goes fine (except for the python-letsencrypt-apache): > 1 mis à jour, 27 nouvellement installés, 0 à enlever et 50 non mis à jour. (sorry forgot the LC\_ALL=C option :s) hope it can help you =) ---

Hello everyone! Sorry about that; the upgrade in backports took a bit longer than expected, so we ended up breaking some installs over the weekend. You should be able to install everything correctly with: `apt-get install -t jessie-backports certbot` or `apt-get install -t jessie-backports certbot python-certbot-apache`, depending on whether you need Apache support. ---

Thank you sir. A moment ago I run: apt-get update apt-get autoremove apt-get autoclean apt-get install -f Then apt-get install python-letsencrypt-apache -t jessie-backports Still the same outcome. ---

The packages were renamed. You’ll need to replace “letsencrypt” with “certbot” in your `apt-get` command. ---

Oh yes duh shame :S I did copy/paste from [https://certbot.eff.org/#debianjessie-apache](https://certbot.eff.org/#debianjessie-apache) Of course now it worked 100% with: apt-get install -t jessie-backports certbot python-certbot-apache Thank you! ---

Hello @ws62003, Take a look to [this post](https://community.letsencrypt.org/t/unable-to-install-certbot/17916/7?u=sahsanu), he is fixing it right now. Cheers, sahsanu ---

I’m still getting the same problem described here, even though I enabled the backports. I’ve done: - adding this to `/etc/apt/sources.list.d/backports.list`: - enabling the backports: but I still get the error. ``` $ sudo apt-get install -t jessie-backports certbot python-certbot-apache Reading package lists... Done E: The value 'jessie-backports' is invalid for APT::Default-Release as such a release is not available in the sources ``` The order of the arguments don’t change the result, `apt-get install python-certbot-apache -t jessie-backports` and `apt-get install -t jessie-backports python-certbot-apache` results the same.
