Can’t connect to a specific Wi-Fi network because of “Reason 2”

This is a new network that I haven’t connected to before, it uses WPA2.

The laptop can connect to my phone’s hotspot and my phone can connect to the problematic Wi-Fi network. As I live with other people I’m not allowed to touch the router and its settings so all I can work with is my laptop.

The problem is I get deauthenticated right after I get authenticated. This is the output of dmesg:

[  583.623274] wlp2s0: authenticate with xx:xx:xx:xx:xx:xx [  583.674097] wlp2s0: send auth to xx:xx:xx:xx:xx:xx (try 1/3) [  583.682346] wlp2s0: authenticated [  583.682581] wlp2s0: associating with AP with corrupt beacon [  583.688023] wlp2s0: associate with xx:xx:xx:xx:xx:xx (try 1/3) [  583.696076] wlp2s0: RX AssocResp from xx:xx:xx:xx:xx:xx (capab=0x431 status=0 aid=6) [  583.698537] wlp2s0: associated [  587.736455] wlp2s0: deauthenticated from xx:xx:xx:xx:xx:xx (Reason: 2=PREV_AUTH_NOT_VALID) 

I have checked that the password is correct multiple times and I have selected Personal WPA2 in the security settings of the network.

What can be the problem?

The item was deleted because it was excluded by a crawl rule

My search crawl is not working for my local site. On my Crawl Log I see a warning:

Item not crawled due to one of the following reasons: Preventive crawl rule; Specified content source hops/depth exceeded; URL has query string parameter; Required protocol handler not found; Preventive robots directive. ( This item was deleted because it was excluded by a crawl rule. )

Important information:

  • I just moved all my content databases to a newly installed Sharepoint on a new server
  • I am running Sharepoint Server 2019 Standard
  • When I change the address in the content source to full FQDN, the search works partially with many 401 warnings
  • The address in question is https
  • Same address with sps3 gets crawled successfully with no issues
  • There is no robots.txt file in the site

I tried and checked everything I could think of, including:

  • I checked that the default access account has access to the website
  • I browsed the website ( using a browser ) while being logging in using the default access account
  • I made sure there are no crawl rules
  • I created a new crawl rule to include the affected URL
  • I did “index reset”
  • I disabled loopbackCheck
  • I used Fiddler to monitor the traffic, the crawler is not even accessing the site

If you have any suggestions, please advice.

Cannot add user because /etc/group.5: lock file already used

I am trying to add a new user when first installing Ubuntu 18.04 LTS and I get this:

Enter new UNIX username: rob groupadd: /etc/group.5: lock file already used groupadd: cannot lock /etc/group; try again later. adduser: `/usr/sbin/groupadd -g 1000 rob' returned error code 10. Exiting. 

It is very similar to this question, however I don’t think the problem is precisely the same as I get this right after download and launch. I have been doing everything as the root user and I know this is bad practice.

This item could not be crawled because the repository did not respond within the specified timeout period

In SharePoint 2019 farm when I run full crawl below error keeps appearing in crawl log, I did below actions but still same error.

Error: The start address xxxx cannot be crawled. Context: Application ‘Search_Service_Application’, Catalog ‘Portal_Content’ Details: This item could not be crawled because the repository did not respond within the specified timeout period. Try to crawl the repository at a later time, or increase the timeout value on the Proxy and Timeout page in search administration. You might also want to crawl this repository during off-peak usage times. (0x80040d7b)

in ULS logs: object not found for (valueName = ServiceUser ProductKeyName = HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office Server.0\Search)

Troubleshoot steps that I did: Given search account Full Permissions and content access account full read permissions from user policy of web application. Add Host Entry for web application in Crawl servers. Disable the Loop back check. Login with content acc account to servers and Internet Options>Connections>LAN settings. Uncheck ‘Automatically detect settings’.

Increase the timeout value on the Proxy and Timeout page in search administration. to 120 Seconds

What actions can prevent you from taking another action because of the restrictions that are placed on the second action? [on hold]

Or in other words: What rules prevent you from doing something you would otherwise be able to do?

I am worried about this question being too broad, but I feel like there can’t be very many examples like the following:

  1. Under the rules on bonus action spells, it states:

    A spell cast with a bonus action is especially swift. You must use a bonus action on your turn to cast the spell, provided that you haven’t already taken a bonus action this turn. You can’t cast another spell during the same turn, except for a cantrip with a casting time of 1 action.

    First, this means that if you cast a bonus action spell, the restrictions on them prevent you from casting non-cantrip spells. However if instead you cast a non-cantrip spell the restrictions on bonus action spells prevent you from casting any bonus action spells. You are normally allowed to cast a bonus action spell, but here, their own rules prevent that. That this is how bonus action spells work is shown here

  2. Under the net weapon, the “special” property states:

    When you use an action, bonus action, or reaction to attack with a net, you can make only one attack regardless of the number of attacks you can normally make.

    First, if you have Extra Attack, and your first attack is with a net, the restrictions on nets prevent you from making more attacks, as shown in this question. However, this question, along with the previous one, possibly show that if you instead make your first attack with, say, a dagger, the restrictions on nets prevent you from attacking with a net. You are normally allowed to attack with a net, but here, its own rules prevent that.

Are there other examples of times similar to these?

Can’t install Ubuntu 18 because sda partitions not visible by installer

Have been struggling for a while with this and had tried different troubleshootings from this forum currently I’m as in the very beginning. While installing ubuntu from usb it doesn’t give the options to select “install along..”, “something else” and so. It jumps direct to installation part where I should select the partition but it doesn’t show any partition.installation part where I should select the partition but it doesn’t show any partition

Server installation fail because “bcache module not found”

When I try to install Ubuntu server 19.04-live-server-amd64 or 18.04.2-live-server-amd64, it fails because an error “bcache module not found”. The bug is this, but it is closed as fixed and released. I can install Desktop images without a problem.

My question is, in the meantime, how to install Ubuntu server. Is there a workaround?

How to delete item in Bin “… cannot be modified or deleted because it is required by MacOS”?

I’m on a 2014 MacBook Air, 10.14.5

A couple of weeks ago I did a quick sweep of my files and drives to get rid of junk, mostly old photos and videos I had accumulated that I didn’t need/want anymore. Everything deleted fine, except for one .mp4 file. This file, it seems, managed to get into my Bin, but is now stuck. I would really like to get rid of it – it was copied off an old USB drive and is about 5GB, which is a lot when you only have 10GB free space.

When I drag it anywhere, it just copies. When the bin is emptied, I get the message “….mp4 can’t be modified or deleted because it’s required by macOS”.

I’ve looked for possible solutions, including turning off System Integrity Protection and reinstalling the OS but to no avail.
Please help! Sorry if I’ve missed any details

maas-dhcpd is not on because bind9 127.0.0.1#954: connection refused

Do anyone know how to resolve this issue?

Service 'maas-dhcpd' is not on, it will be started. Service 'bind9' failed to start. Its current state is 'dead' and 'Result: exit-code'. Reloading BIND failed (is it running?): Command `rndc -c /etc/bind/maas/rndc.conf.maas reload` returned non-zero exit status 1:#012rndc: connect failed: 127.0.0.1#954: connection refused 

I have 2 subnets, one bridge and one local network with 3 interfaces eth0, eth1, br1 my network interfaces:

source /etc/network/interfaces.d/*  # The loopback network interface auto lo iface lo inet loopback dns-nameservers x.x.1.1 dns-search maas  # The primary network interface auto eth0 iface eth0 inet static address x.x.1.2 netmask 255.255.255.0 gateway x.x.1.1 dns-nameservers x.x.1.1 8.8.8.8 8.8.4.4 mtu 1500  auto eth1 iface eth1 inet manual mtu 1500  auto br1 iface br1 inet static address x.x.30.1 netmask 255.255.255.0    bridge_ports eth1    bridge_stp off    bridge_fd 0    bridge_maxwait 0 

Maas subnet configuration from UI: Managed allocation is disabled for below:

Name x.x.1.0/24 CIDR x.x.1.0/24 Gateway IP x.x.1.2 DNS 172.16.1.1 

Managed allocation is enabled for below:

Name x.x.30.0/24 CIDR x.x.30.0/24 Gateway IP x.x.30.1 DNS x.x.1.1 

Running sudo rndc -c /etc/bind/maas/rndc.conf.maas reload ends up with:

rndc: connect failed: 127.0.0.1#954: connection refused 

I’m not sure what am I missing, this MaaS version is 2.5

Additional note: for while i’m investigating, I noticed that there are duplicated entries in named.conf.maas, if I fix the duplicate manually, it will be autogenerated again and back to the same issue.

/etc/bind/maas/named.conf.maas:92: zone 'x.y.z.in-addr.arpa': already exists previous definition: /etc/bind/maas/named.conf.maas:56
