Still won't do, however, modify the yum source fails, try again next time
CodePudding user response:
What you using this source, should not be no GCCModify source this failure can try again, but before that you can try to refresh the source
CodePudding user response:
In the system tray with GCC generally the installation package, just find out directly, can put the disc mount system can't access the network as a source for the installationCodePudding user response:
Can't the network may be the reason for the source of the failure(ping www.baidu.com
Ping: unknown host www.baidu.com),
Refresh the zha operation is the source?
There should be no GCC installation package, this libgcc should be GCC dependent, now also don't know how much
CodePudding user response:
Are you in a virtual machine is this?? True machine should not beIf is a virtual machine on this online tutorial there are many, mostly problems setting up the virtual machine
As to refresh the source ~ ~ ~ yum update, but you deserve good net to say again first
