My Emails a week or so back were about installing Rstudio and the R shiny server on Debian. I was using an old Toshiba laptop as a sandbox for that and it would only install i386 (same for Ubuntu). Using the information at https://cran.r-project.org/bin/linux/debian/ I did get to the point where I had R 3.5.2, Rstudio and the server on there (with some help from Dirk that is in the list archives). However, the server wouldn't start and I knew that the hardware I will need to run it from is amd64 so I stopped there and managed to find another old laptop (an advent) that would install amd64 Debian.
So I downloaded a new clean iso of stretch amd64 and it installed OK but my first time through I seemed to hit a total mess of refusals to load from repositories because of missing release files and/or missing png keys. I lost track of where I'd gone wrong with /etc/apt/choices.list, wiped the installation and started again! I installed a few packages through synaptic: no warnings, fine, I added contrib through synaptic settings: no problems. I installed emacs, no problems! But now I'm stuck and I am hoping to sort things with the help of the list so here's where I am: root@DebianAdvent:/etc/apt# apt-get update Hit:1 [ http://security.debian.org/debian-security | http://security.debian.org/debian-security ] stretch/updates InRelease Ign:2 [ http://mirror.mythic-beasts.com/debian | http://mirror.mythic-beasts.com/debian ] stretch InRelease Hit:3 [ http://mirror.mythic-beasts.com/debian | http://mirror.mythic-beasts.com/debian ] stretch-updates InRelease Hit:4 [ http://mirror.mythic-beasts.com/debian | http://mirror.mythic-beasts.com/debian ] stretch Release Get:5 [ http://cran.ma.imperial.ac.uk/bin/linux/debian | http://cran.ma.imperial.ac.uk/bin/linux/debian ] jessie-cran35/ InRelease [4,369 B] Ign:5 [ http://cran.ma.imperial.ac.uk/bin/linux/debian | http://cran.ma.imperial.ac.uk/bin/linux/debian ] jessie-cran35/ InRelease Get:7 [ http://cran.ma.imperial.ac.uk/bin/linux/debian | http://cran.ma.imperial.ac.uk/bin/linux/debian ] jessie-cran35/ Packages [17.8 kB] Fetched 22.2 kB in 0s (27.5 kB/s) Reading package lists...

OK, that fits the advice about secure apt in Johannes's page so: root@DebianAdvent:/etc/apt# apt-key adv --keyserver keys.gnupg.net --recv-key 'E19F5F87128899B192B1A2C2AD5F960A256A04AF' Executing: /tmp/apt-key-gpghome.qC3CUffAEm/gpg.1.sh --keyserver keys.gnupg.net --recv-key E19F5F87128899B192B1A2C2AD5F960A256A04AF gpg: failed to start the dirmngr '/usr/bin/dirmngr': No such file or directory gpg: connecting dirmngr at '/tmp/apt-key-gpghome.qC3CUffAEm/S.dirmngr' failed: No such file or directory gpg: keyserver receive failed: No dirmngr Might be worth adding a warning about this to that page but I think I can manage this (!) and I installed it using synaptic after this: root@DebianAdvent:/etc/apt# apt-get install drmngr Reading package lists...
