The following information may help to resolve the situation:
The following packages have unmet dependencies:
libgnuradio-runtime : Depends: libvolk2.2 (>= 2.2.0) but it is not installable

最後：
sudo apt-get install libvolk2.2

Package libvolk2.2 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'libvolk2.2' has no installation candidate
尋找 libvolk2.2 表示它位於 Debian 的 sid（不穩定）儲存庫中。然而，當我搜尋安裝 gnuradio 的資訊時，我沒有找到任何關於必須使用 sid 儲存庫的內容。而且如果是這樣的話，我使用的指南似乎也會提到這一點。
因此，在冒險使用 sid 儲存庫並冒著損壞的風險之前，我想看看是否還有其他我沒有看到的需求。
衷心感謝您的幫忙。
非常感謝您的幫忙。
[編輯] 也提一下，這是 18.04 的全新安裝，而 AFAICT 自動軟體更新程式擁有最新的所有內容。
答案1
sudo add-apt-repository ppa:gnuradio/gnuradio-releases sudo add-apt-repository ppa:gnuradio/gnuradio-master sudo add-apt-repository ppa:gnuradio/gnuradio-releases-3.7
您只需新增上述 PPA 儲存庫之一，而不是全部三個。
因此，在冒險使用 sid 儲存庫並冒著損壞的風險之前，我想看看是否還有其他我沒有看到的需求。
是的，目前的軟體包ppa:gnuradio/gnuradio-master似乎已損壞。我剛剛從儲存庫成功安裝了 gnuradio 3.8 ppa:gnuradio/gnuradio-releases。
首先您需要刪除ppa:gnuradio/gnuradio-releases然後ppa:gnuradio/gnuradio-releases-3.7重試安裝gnuradio
rm /etc/apt/sources.list.d/gnuradio-ubuntu-gnuradio-master-bionic.list
rm /etc/apt/sources.list.d/gnuradio-ubuntu-gnuradio-releases-3_7-bionic.list
apt-get install gnuradio
