Thanks! Can you try a more recent version of UHD please to see if it persists?

Hi, I had a question with Gnuradio 3.7.10 or 3.8, UHD version that is used is 3.13 or 3.15. I used the apt-get install command... How can install UHD 4 on Debian ubuntu without compiling it... All work with USRP is in Gnuradio...

You can try a distribution like Debian 11, which has a more recent UHD and GNU Radio.
