OSCAR for Linux can't import data
I am using a ACER CB5-312T Chromebook, M8173C processor. I have downloaded OSCAR for arm64. The installation crashed on the linux pack tracer libdouble-conversion1. I turned out to be for amd64. The OSCAR version for arm64 installing-file is trying to use a package for amd64. So, after some time searching, I found libdouble-conversion1 for arm64. After installing de libdouble-conversion1 for arm64 the installation went fine: OSCAR started and I could setup a profile. But, it was not possible to read the data from my SD-card, whatever I tried to do. The SD-card is visible in ChromeOS and connected to Linux beta, but OSCAR can read the data, but importing the data is not possible. The SD-card is not visible in the Linux terminal. Who can help me?

RE: OSCAR for Linux can't import data
I had the same issue on a Dell Chromebook. OSCAR installed under Linux but could not access the SD card. I installed OSCAR on a Surface Pro and have not spent any time on the Chromebook. I was using a USB SD card adapter by Ugreen that works fine on my Windows machines.

RE: OSCAR for Linux can't import data
First off, we will look into the build process for the ARM Chromebooks; I believe it was built in a virtual box, and that may have caused some problems.
Your SD car should show up in the Linux terminal if you do "ls /mnt/chromeos/removable" Next, check how much space is available for Linux files: In Chromebook Settings, click Advanced, Developers, Linux development environment - what is your Disk Size ? Mine is * GB Then , in terminal, see how much free space is available: If OSCAR_Data is in Documents (the default), do "df /" I found OSCAR ran out of space if I tried to import my many years of data. I changed the Preference item "Do not import before..." to only import the last four or six months of data. I hope this helps - please report back here what works or doesn't. We don't have a lot of Chromebook users, so every bit helps.

It was built with a raspberry pi 3B+ with a Debian 10.11. Normally, the build is tagged as arm64 and supposed to be compatible with the Chromebook. the other pi (pi 4) is with Raspbian 10 (buster). It is used to build the RasPiOS_armhf deb file. If It is not good, I have no Chromebook to build the deb file. The virtual Machines are used to build the Ubuntus & Debian amd64 deb files.

RE: OSCAR for Linux can't import data
Ahh... Thanks for the correction, Untouseul05. Now I have no idea how an amd64 binary could have snuck into an arm64 build.
I'll do a build on my RasPi running Debian 10 to compare with the download site version.

RE: OSCAR for Linux can't import data
Thanks for your contribution. I managed to access the SD-card and import the data. The SD-card seems to be the culprit. I got a new SD-card from my bipap-supplier. She visited me yesterday and gave me a new one, after a nightly O2/CO2-test session. I'm very pleased I succeeded. The commands in the terminal indicated that the SD-card was connected in Linux.
Remains the question why libdouble-conversion1 didn't install OSCAR. My guess is that the file had to be for an arm64 processor, and not for an amd64.

RE: OSCAR for Linux can't import data
libdouble-conversion1 has been superseded by libdouble-conversion2. After searching for a version 1 download, I found that it was easier to create a symlink to version 2, naming it "libdouble-conversion1". All is now well.

RE: OSCAR for Linux can't import data
I just started working with Linux. I used to have MS-DOS machines since 1981, so I have worked with personal computers for 40 years. Nowadays I still have a Windows 10 laptop, an ACER Chromebook, an iPhone and an old iPad. They all work fine. I was curious to install OSCAR on my Chromebook. So I developped an interest in Linux.

RE: OSCAR for Linux can't import data
Careful : libdouble-conversionx is the depends of OSCAR.
On my Ubuntu 20.04 (amd64), it's libdouble-conversion3 not libdouble-conversion1. So, the script shell which build the deb files try to guess the version number and put the right depends. If it doesn't work on your computer : tell us the OS & version of the OS. lsb_release -cdir on Ubuntu OS. On many OS, it's a file with version in the name in /etc folder. then ldd OSCAR/build/oscar/OSCAR | grep conversion sudo find / -name "libdouble-conversion*" 2>/dev/null Like this, we can see if there is a issue on the guess.
