因为核心转储问题而无法运行mongodb？

Question

在Ubunto上安装Mongo后，我遇到了一个问题。当我运行一个命令时

sudo systemctl status mongodb

结果就是

mongodb.service - An object/document-oriented database
Loaded: loaded (/lib/systemd/system/mongodb.service; enabled; vendor preset: enabled)
Active: failed (Result: core-dump) since Fri 2018-09-21 15:32:19 +07; 49min ago
Docs: man:mongod(1)
Process: 5668 ExecStart=/usr/bin/mongod --unixSocketPrefix=${SOCKETPATH} --config ${CONF} $DAEMON_OPTS (code=dumped, signal=ABRT)
Main PID: 5668 (code=dumped, signal=ABRT)
Thg 9 21 15:32:16 saymyname systemd[1]: Started An object/document-oriented database.
Thg 9 21 15:32:19 saymyname systemd[1]: mongodb.service: Main process exited, code=dumped, status=6/ABRT
Thg 9 21 15:32:19 saymyname systemd[1]: mongodb.service: Failed with result 'core-dump'.

请帮我解决这个问题！

我遇到了同样的错误，可能是因为ubuntu从18.04升级到20.04。尝试了很多方法，最后重装mongodb起作用了。这是一个新的安装，所以不关心备份。

$ sudo apt remove mongodb mongo-tools mongodb-clients mongodb-server mongodb-server-core
$ sudo apt autoremove
$ sudo rm -rf /var/lib/mongodb/
$ sudo apt install mongodb
