[GuzzleHttp\Exception\RequestException] cURL error 60: SSL certificate problem: certificate has expired (How to Solve)

[Solved] Github Action Error: Error: Unable to process file command ‘env’ successfully.

I need to read text from a local file, usually in bash execution cat ./fileName, so I took it for granted

echo "FILE_TEXT=$(cat ./file.txt)" >> $GITHUB_ENV

Then report the error as follows

Error: Unable to process file command 'env' successfully.
Error: Invalid environment variable format 'xxxxxxxxxx... '

The reason is because setting $GITHUB_ENVthe environment variable does not directly support multiple lines of text, plus get EOFthe job
following this set on it

name: "Read the text"
run: |
       echo 'FILE_TEXT<<EOF' >> $GITHUB_ENV
       cat ./file.txt >> $GITHUB_ENV
       echo 'EOF' >> $GITHUB_ENV

run: |It is to run multi-line shell commands. Local variables can be obtained in this step. Those who need to obtain values across steps must be written $GITHUB_ENVto, and then the reading method is as follows:

${{env.FILE_TEXT}}

Bringing up interface eth0: Error: No suitable device found: no device found for connection ‘System eth0’. [FAILED]

1. Description: virtual machine configuration IP restart network card: service network restart error message:

The error information is as follows:

[root@localhost network-scripts]# vim ifcfg-eth0
[root@localhost network-scripts]# 
[root@localhost network-scripts]# service network restart
Shutting down loopback interface:                          [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0:  Error: No suitable device found: no device found for connection 'System eth0'.
                                                           [FAILED]

2. This problem occurs because the network card actually assigned to the virtual machine does not match the network card information in the configuration file

1. The actual network card information allocated to the virtual machine is: [hwaddr 00:0c: 29:7f: B6: FF]

root@localhost /]# ifconfig
eth1      Link encap:Ethernet  HWaddr 00:0C:29:7F:B6:FF  
          inet6 addr: fe80::20c:29ff:fe7f:b6ff/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:68 errors:0 dropped:0 overruns:0 frame:0

          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1

          collisions:0 txqueuelen:0 
          RX bytes:3760 (3.6 KiB)  TX bytes:3760 (3.6 KiB)

2. The network card information in the configuration file is:

vim /etc/sysconfig/network-script/ifcfg-eth0

DEVICE="eth0"
BOOTPROTO="static"
IPV4_FAILURE_FATAL="yes"
BOOTPROTO="dhcp"
HWADDR="00:0C:29:7F:B6:8A"
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="5c4e89fb-eced-4d66-962a-e5f6e565ec26"
IPADDR="192.168.25.135"
NETMASK="255.255.255.0"
GATEWAY="192.168.25.1"
DNS1="192.168.25.1"

3. Modification method: the above configuration files are configured according to the network card actually allocated to the virtual machine, that is:

HWADDR="00:0C:29:7F:B6:8A" Modify to HWADDR="00:0C:29:7F:B6:FF"
Save the pair to exit: restart the NIC: service network restart Correct

[Solved] git pull Error: error: Your local changes to the following files would be overwritten by merge

The reason for this error is that you have modified the file locally and remotely at the same time

Solution:

Keep local files

git stash
git pull origin master
git stash pop

Do not keep the local file (restore the local file to the previous version and pull down the remote modification)

git reset --hard
git push origin master

[Solved] carla-simulator Start Error: libomp.so.5 file cannot be found

ubuntu20. 04 because the system has been upgraded, some useless packages have been automatically uninstalled, and the Carla that can run originally cannot be started and an error is reported:

/opt/carla-simulator/CarlaUE4/Binaries/Linux/CarlaUE4-Linux-Shipping: error while loading shared libraries: libomp.so.5: cannot open shared object file: No such file or directory

Solution:

Try reinstalling the libosm5 package

sudo apt-get install libomp5

After the installation is completed, start Carla again successfully.

apt-get install imagemagick libmagickwand-dev

If: error: no suitable Python interpreter found

Note: there is no Python environment or the required versions of existing Python and ZBar are inconsistent. If Python is not involved, add the parameter — without python

If: configure: error: Test for video support failed
rebuild your kernel to include video4linux support or
configure –disable-video to skip building video support.

Add — Disable video parameter

For example, my final execution /Configure parameter:

./configure FLAGS="" --disable-video --without-python --without-qt

[Solved] item2 Error: a session ended very soon after starting. check that the command in profile default

At the weekend, the Alibaba cloud ECS instance password was modified. When Item2 was used to remotely connect to the server again, the following error was reported:

reason

Every time a new connection ssh remote use, will be in ~/.ssh/known_hoststhe secret documents generated ssh key pair on updating the remote password, you need to delete the corresponding ssh keys. Otherwise, an error will be reported.

Solution

Locate the file ~ /.SSH/known_Hosts, find the IP you want to connect remotely and delete the corresponding secret key. For example, I connect remotely 47.98.202.133, and delete the box in the following figure:
