Elpy: Cannot install elpy

[triplrrr]

I have been unable to install elpy to my emacs installation. I tried to install it and I got the following result.

Contacting host: melpa.org:80
package-install-from-archive: http://melpa.org/packages/yasnippet-20190423.206.el: Not found

I have not tried to reproduce on other machines, but I have been so far unable to install on my machine regardless of a restart of emacs, refreshing my package list, or a restart of my machine.

My config is here. I am running Kubuntu 18.10 with KDE. My Emacs version is Emacs 25.2.2.

(elpy-config) gave the following result

eval: Symbol’s function definition is void: elpy-config

There is no config for elpy in my ~/.emacs file.

Looks like one of the dependencies for elpy is missing from the melpa repository.
yasnippet-x.y.el: Not Found

Note to self: Looks like we might have to bump the yasnippet version? verified that it's not on the melpa repo anymore. 🤔

@gopar this sounds like a transient MELPA bug. eg, the following links appear to be valid:
https://melpa.org/packages/yasnippet-20190502.2214.el
https://stable.melpa.org/packages/yasnippet-0.13.0.el
@triplrrr, you don't need to use yasnippet from MELPA, because cosmic has 0.13.0. sudo apt install elpa-yasnippet

[triplrrr]

@sten0 thanks, but now I get a different error message

package-install-from-archive: https://melpa.org/packages/ivy-20190516.1513.tar: Not found

Elpy doesn't require ivy, so it shouldn't prevent elpy to work.

However you do seem to have a problem with package management.
Would running this help ?

(package-initialize)
(package-refresh-contents)
(package-install 'ivy)

[azzamsa]

@triplrrr is this problem persists ?

[olishmollie]

I encountered this issue also. Solved it with "M-x package-install RET elpy RET". So for me, I only got the ya-snippet error through use-package's :ensure directive. Maybe the bug lies there?

[nackjicholson]

@azzamsa Yes this problem still persists. I get the same thing using M-x package-install RET elpy RET as well.

From package-install

From use-package

Error (use-package): Failed to install elpy: http://melpa.org/packages/yasnippet-20190630.1720.el: Not found

@galaunay Help! I noticed you were able to merge #1613 to fix a similar problem. Could you do that again to use the current version of yasnippet on melpa?

[galaunay]

I updated Yasnippet version during the same commit, so it should be alright.

Your Emacs is trying to download a version of yasnippet (20190630.1720) that is not on Melpa's server anymore (the current version is 20190724.1204).

Emacs should automatically refresh the package list before installing any package.
For you, it is apparently not happening...
You can force Emacs to do it with M-x package-refresh-contents.
Is it running properly (without errors in *Messages*) ?

[galaunay]

I hope this is fixed now, please re-open if not.
