Raspberry Pi DPKG error

[SRees]

Hi All,
Im trying to install 3cx on my raspberry pi. I have done this previously and have had no issues.

For the last 3 days I have had this as my main issue

dpkg-deb (subprocess): decompressing archive member: lzma error: compressed data is corrupt
dpkg-deb: error: <decompress> subprocess returned error exit status 2
dpkg: error processing archive /tmp/apt-dpkg-install-ZsxFfN/70-3cxpbx_18.0.2.314_armhf.deb (--unpack):
 cannot copy extracted data for './usr/lib/3cxpbx/System.Private.DataContractSerialization.dll' to '/usr/lib/3cxpbx/System.Private.DataContractSerialization.dll                   .
.dpkg-new': unexpected end of file or stream
Errors were encountered while processing:
 /tmp/apt-dpkg-install-ZsxFfN/70-3cxpbx_18.0.2.314_armhf.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

I had originally tired to install this on bullseye (new raspberian / debian) but found it didnt work so went back to buster.

but keep getting the same error any ideas ?

Are you following this guide?

https://www.3cx.com/docs/installing-pbx-raspberry-pi/

I would format your SD card again with the image from the website.

May have found the issue its a pi b+

Last one I did was a 3 b+

this pi may be too old

But yes I did use the guide above. Like I said I have set this up before but had no issues.

Have tired with the image above as well as the image direct from raspberrypi.com same results

have also tired 2 different SD cards one being brand new

The Pi b+ is old indeed and probably the reason you're having the issue. We actually recommend the Pi 4(B4 or B8), but, in light of the hardware shortage, you could potentially try using a Pi 3B+ if you have one instead.
