When updating the Linux system, the system prompts that the VaR space is insufficient.

Cause Analysis 1:
If/var is partitioned separately, it may be because the partition capacity is too small. when updating the system or installing large software, the/var directory is used. Therefore, insufficient space is prompted. Use the following method to solve the problem.

Method 1:
Sudo apt-Get clean
Sudo apt-Get autoremove
Restart the machine. If there is still insufficient space, use method 2.

Method 2:
Use symbolic links to determine ﹕
MV/var/spool/home // first move the large directory in/var to/home or another directory with sufficient space.
Ln-S/home/spool/var // create a symbolic link. /Var/spool points to/home/spool to solve the problem of insufficient var space.

 

Cause Analysis 2:
If/var is not partitioned separately, the system shares the/home directory by default. If the/var space is insufficient, the/home space is insufficient. In this case, we recommend that you reinstall the system, re-plan the partition structure. In general, the/var directory 2g-4G is better, or it is not partitioned and shared/home.
