As usual, I typed cd in the linux terminal, then clicked tab and hoped that the system would automatically complete the code for me, but this error was reported.
After some analysis, I found that my disk space was full.

/dev/vda1 236M 33M 191M 15% /boot
Here:
/dev/dm-0 7.8G 5.2G 2.6G 67% /
Now it shows 67%, it was 100% when the error was reported before
So switch to: cd /
Switch to administrator: su root
Then type:
du -lh --max-depth=1
31M ./boot
3.4M ./etc
0 ./media
2.1G ./var
1.2G ./usr
204M ./lib
0 ./lib64
8.9M ./bin
7.5M ./sbin
It can be seen that the space occupied by ./var is relatively large
So cd to this directory and continue typing
du -lh --max-depth=1
solve
I finally located two log files, which took up a lot of space. After confirming that the deletion would not bring any adverse effects, I directly rmed them out.
restart syslog
If Ubuntu
deletes syslog, it is best to restart it
service rsyslog restart
Alternatively, this
systemctl restart rsyslog
