Running certbot just returns with no action

Help
21

Whoops, that last part was asking you to run certbot. Silly phone keyboard. Also you already posted that so ignore this part. Maybe a bit tired myself. =]

Illegal instruction is interesting though. Could you paste the exact output? That looks like the best string to pull on for now.

root@raspberrypi:/home/pi# certbot certonly --webroot -w /var/www/html -d X.netgear.com
Illegal instruction
23

hi, back from my brotherā€™s wedding this weekendā€¦ would still love to figure this out

24

reply with results of:
which certbot
and also
certbot --version

25 
pi@raspberrypi:~ $ which certbot
/usr/bin/certbot
pi@raspberrypi:~ $ certbot --version
Illegal instruction

is it possible the rpi i am running my server on is too old? and the illegal instruction is because the processor architecture doesnt understand some of the instructions? it is a fairly old pi i had laying around, not sure the modelā€¦ i can check

pi@raspberrypi:~ $ lscpu

Can you upgrade the pi software?

27

I would suggest trying

gdb python

and then at the (gdb) prompt

run /usr/bin/certbot --version

Edit: although I donā€™t know if you have gdb installed or not

28

if needed, i dont see why not... is that the issue?

Not sure but it can't hurt.

30

iā€™ve installed the latest OS (within the past month or so) and ive run apt-get update/upgrade

what else would i need to do?

31

Getting the certbot version would be nice:
/usr/bin/certbot --version
sudo /usr/bin/certbot --version

32

ive tried that many timesā€¦

pi@raspberrypi:~ $ certbot --version
Illegal instruction
pi@raspberrypi:~ $ sudo certbot --version
pi@raspberrypi:~ $ /usr/bin/certbot --version
Illegal instruction
pi@raspberrypi:~ $ sudo /usr/bin/certbot --version
pi@raspberrypi:~ $

This is the underlying problem that is making it crash.

Maybe you can start by trying to reinstall this package in case this binary is somehow corrupted.

dpkg -S libcrypto.so.1.0.0 to find out the package name

then

sudo apt-get install --reinstall [that package name]

By the way, if the package is libssl1.0.0, there is also a version libssl1.0.0-dbg which has debugging symbols. If you switch over to that package, then running with gdb as before would show what the library was trying to do when it crashed; you could run backtrace at the post-crash (gdb) prompt to see a list of calls inside the library and learn the specific context of the crash.

34 
libssl1.0.0:armhf: /usr/lib/arm-linux-gnueabihf/libcrypto.so.1.0.0

so i would use the command below?

sudo apt-get install --reinstall libssl1.0.0:armhf
35

Yes, Iā€™d suggest trying that.

36

did you run this command?

37

i ran the reinstall command, and tried againā€¦

same error

38

Could you try with libssl1.0.0-dbg:armhf?

39

sure, do I need to install that lib, or how do I force it to use the debug lib?

sudo apt-get install libssl1.0.0-dbg:armhf

?

40

Yes, that should work, I think.
