Mint wobbly
by Bev Nicolson 23 Jul '21

23 Jul '21

Not really sure what's up. A couple of times my laptop has frozen. Either the program won't respond or won't launch. I've had to do a fsck check each time to get back in or I'd be stuck in initramfs, unable to log in again. (My phone had not packed up so I was able to google this info.) Anyone got any ideas? Bev.

uMatrix and Firefox
by Peter 22 Jul '21

22 Jul '21

Hi everyone, thought this might be useful to someone. Suddenly Firefox stopped connecting to any sites. At the same time, email worked fine and all the other browsers worked fine. So I disabled all the extensions, and it now connected. Turned them back on one at a time, and so discovered that uMatrix was the problem. Played with all the uMatrix preferences and settings to no avail. Found various explanations and suggestions, none of which worked for me. Turned out that installing the latest version from github fixed it. I think it probably is just due to having changed the sources of the blocking lists, in assets. uMatrix I find really useful - proper detailed control of what's going on. Sorry that he has decided to stop updating it, but this latest version seems to work fine, for now. Debian stable, so mine is a few releases behind the latest Firefox.

Kubuntu updated nvidia drivers behind my back?
by Srdjan Todorovic 21 Jul '21

21 Jul '21

Hi all, I had an nvidia driver module update behind my back, while the system is running. I did not issue an apt-get upgrade, or enter my sudo password anywhere. Yet, launching any application that uses GLX (e.g. glxgears) gives me this: X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 151 (GLX) Minor opcode of failed request: 3 (X_GLXCreateContext) Value in failed request: 0x0 Serial number of failed request: 35 Current serial number in output stream: 36 And dmesg output is full of entries that tell me that the Nvidia client is newer than the running kernel module version. I've had this before, and the usual remedy is to reboot. It's just that I didn't (knowingly) authorise the system to do an update. Anyone know what might be doing these unattended updates? It'd be useful to know, so I can schedule the updates at the end of the day. Thanks, Srdjan

Firefox 90 - toolbar text illegible
by Bev Nicolson 19 Jul '21

19 Jul '21

I've got a screenshot of what I mean but I'm not really sure what the best way of posting that is. The problem is this though. I updated to Firefox 90 and cannot use any dark theme now. The menu options File, Edit, View, History etc become almost the same colour as the border. I've noticed that if I want to check the progress of a download that's hard too. What have they done? I have tried switching proton off (those with context, doorhangers, enabled and modals as part of the text) but it didn't work. Firefox suggested using the troubleshooting tool. I confess I'm unconvinced how that will help. Cinnamon Mint 19. Ideas? I am using Firefox colour in the meantime, but it doesn't solve it. Bev.

Zoom on Linux?
by Steve Mynott 06 Jul '21

06 Jul '21

Does anyone regularly and successfully use the Zoom app on Linux? I've had it working in the past but it's not 100%. Frequently the audio output seems to break (remote person can hear me but I can't hear them). Does anyone use the web version? I've not really had any problem with Teams just Zoom. I'd really not use any of these but its often not my choice. -- Steve Mynott <steve.mynott(a)gmail.com> cv25519/ECF8B611205B447E091246AF959E3D6197190DD5

Linux Mint updates issue
by Bev Nicolson 24 Jun '21

24 Jun '21

Right after I've logged in, I can update anything that needs updating, via the Update Manager. After that, I just a get a red cross in the shield and the message 'Could not refresh the list of updates.' Ideas? I've tweaked the sources list but that does nothing. Bev.

Lets Encrypt renewals via DNS
by Mark Rogers 21 Jun '21

21 Jun '21

Sometimes you can't find the answer to your question on line. This is one of those examples where the answers seem plentiful but I can't get my head around them. I have a couple of domains with Lets Encrypt wildcard certificates. Creating the certs manually is easy (if a bit laborious): add the specified ._acme_callenge DNS entry and a handful of files under docroot .well-known/acme-challenge. But they can't be renewed automatically so every three months I need to go through the whole process again. Reading the docs, if my DNS is with one of the supported DNS providers (eg DigitalOcean, who I have an account with) then it can be automated via the API (the files under docroot I think can be automated with the --apache plugin?) but that's not where my DNS is. The docs suggest that I can use a CNAME but don't go beyond that. Has anyone done this, or otherwise automated wildcard certificate renewals where the DNS isn't in a supported provider? Also (probably simpler): once the certificate is created, can all the .acme-challenge files and DNS records be deleted? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0344 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Ubuntu upgrade disaster
by Jenny Hopkins 21 Jun '21

21 Jun '21

Hi folks, I'm attempting to upgrade from Ubuntu 18.04 -> 20.04. The 18.04 has been brought completely up to date, and has no broken packages. However, when I run " sudo do-release-upgrade -d", the system starts preparing for the upgrade then bails out. The log file shows: 2021-06-20 09:39:31,393 DEBUG Marking 'ubuntu-desktop' for upgrade 2021-06-20 09:39:31,850 DEBUG Marking 'xubuntu-core' for upgrade 2021-06-20 09:39:32,694 WARNING Can't mark 'xubuntu-core' for upgrade (E:Unable to correct problems, you have held broken packages.) 2021-06-20 09:39:32,694 DEBUG Marking 'xubuntu-desktop' for upgrade 2021-06-20 09:39:33,631 WARNING Can't mark 'xubuntu-desktop' for upgrade (E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.) 2021-06-20 09:39:33,632 DEBUG Marking 'ubuntu-mate-core' for upgrade 2021-06-20 09:39:34,559 WARNING Can't mark 'ubuntu-mate-core' for upgrade (E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.) 2021-06-20 09:39:34,561 DEBUG Marking 'ubuntu-mate-desktop' for upgrade 2021-06-20 09:39:35,491 WARNING Can't mark 'ubuntu-mate-desktop' for upgrade (E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.) 2021-06-20 09:39:39,951 ERROR Dist-upgrade failed: 'Broken packages after upgrade: xubuntu-core, xubuntu-desktop' 2021-06-20 09:39:39,952 DEBUG abort called However, I don't have any broken packages - both the graphic packages manager and CLI searches confirm this. Trying to run the upgrade from the GUI just crashes. Can I do this the debian way, and alter the sources file and do the upgrade that way? Many thanks, Jenny
