When trying to install RIOT I encounter the same issue as LaurantM
(apparently - I don't really speak French):
https://trisquel.info/en/forum/probl%C3%A8me-install-riot
When following the instructions at https://riot.im/download/desktop/ I get:
~$ sudo apt update
Hit:1 http://es.archive.trisquel.info/trisquel flidas InRelease
Hit:2 http://es.archive.trisquel.info/trisquel flidas-security InRelease
Hit:3 http://es.archive.trisquel.info/trisquel flidas-updates InRelease
Ign:4 https://packages.riot.im/debian flidas InRelease
Err:5 https://packages.riot.im/debian flidas Release
404 Not Found
Reading package lists... Done
E: The repository 'https://packages.riot.im/debian flidas Release' does not
have a Release file.
N: Updating from such a repository can't be done securely, and is therefore
disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration
details.
In response to LaurantM MagicBanana's seems to be advising to go via
https://packages.riot.im/debian. I have tried that but seems to fail. I have
downloaded .asc .gpg and the .deb files via
https://packages.riot.im/debian/pool/main/r/riot-web/ (I am by no means sure
that that is the right place to download from). Now I am stuck because I
can't find answers to how to gpg --verify the riot-web_1.5.9_amd64.deb file.
What am I doing wrong and how can I do it right?
