Your Question is unclear, in particular you have provided no information about the networks you are attempting to access, what interface you are using or diagnostics so it unclear whether you actually have a problem. sudo dhclient -v eth0 will show detail of lease negotiation on eth0. You can force release of a lease with dhclient -r although this in usually ...

Are you sure you are still using ALSA only? The Pi OS has recently switched to PulseAudio, so if you're using an up-to-date system you may want to poke around Pulse settings. Checking the kernel log (sudo dmesg) and the list of loaded modules (lsmod) might also help. Personally I would start by unloading the driver sudo rmmod <driver-name>, loading it ...

It's possible that you can repair your SD card with fsck; aka e2fsck & fsck.vfat. There's a recent answer that will walk you through the process. This may not help, but it's not a huge effort - "nothing ventured, nothing gained" as they say. You might also review man e2fsck for background. Since you are now booting from a USB SSD, you may be ...

Do not attempt to apply ANYTHING in that link, which is a different error. What the message means is partition 2 (of whatever drive contains the root file system) is CORRUPT, or missing. What you are suggestion may be possible to a sufficiently skilled user, but most wouldn't even attempt this with a faulty OS and creating a bootable SSD is not entirely ...

Your question is unclear but if you are using ICS the Pi will have internet access BUT you will not be able to access it from the laptop. Connect the Pi to your router. The only option is to turn your laptop into a router which is off topic.

Although there are multiple sources on the internet which seems to be the same for the Dymo LabelWriter 450 printer driver --- same version code, same file names ---, I was able to install it from this repo. I've decided to try it out, because its README mentions a patch implemented in the code. Even though it was not clear that it patched the cups location ...

No. Do not install it in /usr/bin. /usr/bin is for programs installed by the package manager. If you install packages manually, they go in /usr/local/bin (or ~/.local/bin etc.). You can use the --prefix option of the configure script to select the folder to install it to, by default the prefix is /usr/local. As mentioned in (1), don't set it to /usr or you'...

With Joan's help the solution is to refer to the absolute path of rails rather than rely on rvm. which rails - provides an absolute path, in my case /home/pi/.rvm/gems/ruby-2.5.3/bin/rails. You then need to replace bin with wrappers as per this answer. You can add your command to the file .xsessionrc in your home directory, this is run after logging into the ...

If you want to keep what is on the SD Card DO NOT attempt to "fix" it. Mount the card in an adapter (on the Pi or any Linux computer) and copy your files.

I encountered the same issue when I upgraded my Raspberry Pi from Stretch to Buster. This is headless pi, used to run report from my weather station, so there is no display, keyboard or mouse attached to the system. RealVNC worked reliably before the upgrade, but after the upgrade RealVNC connected but presented the "Cannot currently show the desktop&...

So here's how I found the solution. I had a speech.sh which was an executable script in another folder, so the permission to run it was local to that folder which I wasn't aware of. So I copied it to the local read_news folder and ran sudo chmod 755 {script name } and deactivated my venv and ran pip3 install feedparser and that did it for me.

to me it is broke on every raspberry pi 4 qty(4+), with any power supply I use. I plug in a wifi dongle, boom I'm connected. raspberry pi 4 wifi in US on 2.4ghz band is fubar. Think I can setup a 5ghz ap, but that is not the issue, I'm getting server wpa_supplicant[2648]: wlp8s0f3u3: AP-STA-POSSIBLE-PSK-MISMATCH dc:a6:32:20:e3:4a server wpa_supplicant[2648]: ...

The answer from meuh is right but perhaps using pipexec better. Ultimately I discoeverd a minor error in the pipexec command which when fixed ran exactly as I wanted it to (now corrected above). Been running for the best part of 2 months with information being written to a Oetiker RRD through a command (rather than trying to get the actual RRD 'C' library ...

As @Milliways pointed out, openmediavault (OMV) disables dhcpcd. Therefore, I doctored a netplan-yaml-file which I found on the net and it seems to do the trick: $ cat 30-bridge.yaml network: ethernets: eth0: match: macaddress: dd:aa:33:dd:00:aa #accept-ra: true dhcp4: false dhcp6: false bridges: br0: ...

If you want to restore default settings for Raspberry Pi OS, just flash its image to the SD Card.
