Hi,

I'm new to Yocto and am trying to follow the quick start guide to get up and running with poky.  I'm using the latest Dunfel 3.1.2.

I'm running Debian 10 Buster in a VirtualBox VM (guest), on a Windows 10 Pro (host).

I'm having trouble with the build fetching files and getting checksum mismatch, however if I download the troublesome file with wget then the checksum is correct.

How do I fix this?

Everything seems very complex with Yocto, but maybe that's because I'm new to it.

Hi Brendan,

Could you inspect the file in
/home/brendan/SEPL/Projects/Erntec/PMU/yocto_trial/poky/build/downloads/m4-1.4.18.tar.gz
to see if it is some kind of HTML file stating a download error?

Check the file size, if it's small it's probably an error so open it
using an editor to see if you get any hints. Many corporate networks
will require the use of a proxy server, see e.g.
https://wiki.yoctoproject.org/wiki/Working_Behind_a_Network_Proxy for
hints on that.

Cheers,
Erik

everytime checksum is changing, thats not normal. Have you tried

bitbake -cccleanall m4 ; bitbake m4

and see if that helps ?

secondly, check for any mirrors or pre-mirror settings your distro might have which is getting this tarball from elsewhere, the checksums are correctly mentioned in recipe, it should match those of downloaded tarball.

Hi Brendan,

Could you inspect the file in
/home/brendan/SEPL/Projects/Erntec/PMU/yocto_trial/poky/build/downloads/m4-1.4.18.tar.gz
to see if it is some kind of HTML file stating a download error?

Check the file size, if it's small it's probably an error so open it
using an editor to see if you get any hints. Many corporate networks
will require the use of a proxy server, see e.g.
https://wiki.yoctoproject.org/wiki/Working_Behind_a_Network_Proxy for
hints on that.

Cheers,
Erik

Hi,

I'm new to Yocto and am trying to follow the quick start guide to get up and running with poky. I'm using the latest Dunfel 3.1.2.

I'm running Debian 10 Buster in a VirtualBox VM (guest), on a Windows 10 Pro (host).

I'm having trouble with the build fetching files and getting checksum mismatch, however if I download the troublesome file with wget then the checksum is correct.

How do I fix this?

Everything seems very complex with Yocto, but maybe that's because I'm new to it.

Thanks,

Howdy!

Its a long shot, but are you also using WSL2 on the Windows 10 Host?
In that case, downloads into a VirtualBox VM can be corrupted, see
https://www.virtualbox.org/ticket/19695

Hi Josef,

It actually might not be that much of a long shot.  I am using WSL2 on Win 10 Pro, and I have had trouble with connecting my VS Code Remote SSH to my VirtualBox VMs.  Standard ssh from the command line works, but vscode remote ssh doesn't connect (when it used to).  Also having issues upgrading an Ubuntu 20.04 VirtualBox VM.

Might try disabling disabling WSL and see if that improves things.

Brendan.
