I get this error trying to install N1:

On fresh install of ubuntu 15.10
I solved this by first installing libgcrypt11 from an older ubuntu version first:
32bit: https://launchpad.net/ubuntu/+archive/primary/+files/libgcrypt11_1.5.3-2ubuntu4.2_i386.deb
64bit: https://launchpad.net/ubuntu/+archive/primary/+files/libgcrypt11_1.5.3-2ubuntu4.2_amd64.deb
Ubuntu is transitioning from libgcrypt11 to libgcrypt20 and have set up a linked package during the transition. The nylas package doesn't seem to understand the link though (my understanding of deb packages is minimal). I don't know if this is an Ubuntu bug or a bug in the N1 deb package.
This fixed it for me too..
This seems to be a electron issue rather then N1.. Closing
This affects also Ubuntu 15.04.
May I ask you why you close this ticket? In my opinion N1 should not depend on obsolete version of libgcrypt. A real solution should be to compile N1 against libgcrypt newer version.
clobrano is right from my point of view
Ubuntu suggest to contact software maintainer rather then messing with security packages, but this is not only happening to N1, Spotify and others are having same issue...
Ill reopen this issue.. from my understanding this was something related to electron so it was affecting all electron applications.. But I can't remember where i saw it, neither can I find it.. I must have been dreaming!
Duplicate of #55
Closing this as a duplicate of https://github.com/nylas/N1/issues/55鈥攚e're working on a fix for this and should have it resolved soon, but you can track the conversation there.
I installed "libgcrypt11" and able to install brackets software... But is there a way to change the dependency of brackets to libgcrypt20....
I installed "libgcrypt11" and now able to install staruml software. Thanks
thanks so much
