libzstd が削除され、dpkg または apt が機能しなくなりました

aptorを使用して何も実行できdpkgません。例えば、

$ sudo apt install sl
apt: error while loading shared libraries: libzstd.so.1: cannot open shared object file: No such file or directory

libzstd次の方法で手動でインストールしようとしました。

$ wget http://ftp.us.debian.org/debian/pool/main/libz/libzstd/libzstd1_1.4.8+dfsg-1_amd64.deb
$ sudo dpkg -i libzstd1_1.4.8+dfsg-1_amd64.deb
dpkg-deb: error while loading shared libraries: libzstd.so.1: cannot open shared object file: No such file or directory
dpkg: error processing archive libzstd1_1.4.8+dfsg-1_amd64.deb (--install):
 dpkg-deb --control subprocess returned error exit status 127
Errors were encountered while processing:
 libzstd1_1.4.8+dfsg-1_amd64.deb

これは、 とのquicksilver-rocksdb依存関係の競合があるプライベート リポジトリ ( )からパッケージをアンインストールした後に発生しましたlibzstd。/var/log/apt/term.logここで提案されているように、ここの関連セクションを添付しています: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1764858実行中に発生しましたsudo apt remove quicksilver-rocksdb。

しかし、それも明らかに機能しませんでした。
