No longer able to install on Raspberry Pi

Support
1

I have many Raspberry Pi 3 Model B+ systems syncing, they are running V1.14.0 (stable version)

But when I try to install on more Raspberry Pi using the Debian/Ubuntu Packages as usual from the website they fail to work.

The GUI looks fine but they never connect.

The first sign I have that its not going to work is that nothing has been added to /usr/share/applications.

I notice that the Version shown in the GUI is: v0,14.18-dfsg1, Linux (ARM)

Any help would be appreciated

(If I make a disc image of an old Raspberry Pi it works fine)

Thanks, Pete

0.14 is much much older than 1.4. Follow the install instructions from our site, rather than just blindly ā€œapt-getā€ installing it, as the version of the OS you use ships an ancient package.

Hi,

I never ā€˜blindly ā€œapt-getā€ā€™ I am following the instructions completely from your site, I have installed on numerous Raspberry Pi and it has always worked very wellā€¦but now Iā€™m unable to make them work as I said.

This is what Iā€™m using: https://apt.syncthing.net/

On the one thatā€™s showing 0.14.18-dfsg1, something went wrong then, and you didnā€™t actually get the package from apt.syncthing.net but from debian repos. Recheck you got the apt source set up right.

Thanks Simon,

I will do it again tomorrow and if it doesnā€™t work Iā€™ll send all the text from command prompt so that you can see what Iā€™ve actually installed. Iā€™ve done it dozens of times before but now Iā€™ve failed on 5 different installsā€¦very strange.

Hi All,

I have attempted to install again on a fresh Raspberry Pi which has never had Syncthing installed on it. Iā€™m afraid that the result is the same and it doesnā€™t work.

No items have been added to: /usr/share/applications

I have attached a text document showing all the text from the command prompt during installation.

I think that there are a couple of lines worth looking at, at the end of the apt-get update sequence, just before apt-get install syncthing:

E: Failed to fetch https://apt.syncthing.net/dists/syncthing/stable/binary-armhf/Packages server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none E: Some index files failed to download. They have been ignored, or old ones used instead.

I have also attached a screen grab showing the version of Syncthing that has been installed. v0.14.18-dfsg1,Linux (ARM)

Thanks for your help. Pete

Actually I canā€™t find how to attach documents to this post, let me know if its possible, or I can paste the full text from the command prompt here if it would be useful.

your CA File is outdated and doesnā€™t include the Letā€™s Encrypt CA Cert, but only the third-party one, which has been invalid for some weeks.

So all your other raspberry pis should not be able to update syncthing either.

ok thanks

Do you know how I correct this?

Thanks, Pete

11

should be

sudo apt install ca-certificates

Great thanks for your help,

Iā€™ll give it a go a little later

Hi,

Iā€™m afraid that running ā€˜sudo apt install ca-certificatesā€™ has not solved the problem. I ran it and then completely reinstalled Syncthing but the result is the same.

You may also need to use that to update certs: sudo update-ca-certificates.

15

Thanks Simonā€¦I will try

Pete

No same result iā€™m afraid. I wasnā€™t sure in which order to try, update certificates before install certificates or the other way roundā€¦so I tried both.

There are several certificates in that location but I suppose not the correct one

Pete

I get this message when trying install ca-certificates, is this the version that would be expected?

ca-certificates is already the newest version (20200601~deb9u2)

I get this message when trying apt update:
