Creating a different user account for it is out of the question btw, since you can still change the password for that user via the primary admin account.

First of all, if users have admin rights, nothing really prevents them to run that app. Even if you encrypt the app itself, they can just reinstall/replace it from standard repository.

Few ways this can be done:

1. If app needs internet connection, you may use firewall rules to block said connections, or even application firewall (Opensnitch). Create script which unloads said rules via su (create diffrent accounts with passwords the user must know) then runs app, and after closing app loads rules again. Users must not have admin rights or they can just unload fw rules.

2. Create encrypted container/directory, protected by password, and manually install said app under there (probably needs manual recompile of the app). Create script which asks password, unlocks the encrypted location, runs app, and locks container after use. Again, no admin rights for users or they just install same app from repositories.

3. Use apparmor or selinux to block said app. And again create script which by using su (create diffrent accounts with passwords the user must know) allows app via selinux/apparmor policies and runs app, and blocks it again afterwards. I repeat, users must not have admin rights or they can just unload those blocks.

What app it is?

EDIT: Clarification for su usage

To have user asked password before app can be done via su + sudo like this

• create user demouser
• give password of that user to end user
• give demouser sudo rights to run particular command as root without password (to unload fw rules, unload apparmor/selinux policy etc).

Same workaround works here as with dirty frag. Just disable those kernel modules.

I would use Ubuntu LTS (free) or Redhat Enterprise Linux. If paying is not an option, some RHEL derivate would probably also work.

Care to elaborate how Ubuntu failed newest release?

Systemd has already won. So other init systems must adapt, and modify themselves to be compatible with systemd.

You are trying to install wrong versions of nvidia drivers and proton app.

For nvidia, use this https://linuxconfig.org/how-to-install-nvidia-drivers-on-ubuntu-26-04

For proton vpn, I assume you are trying to install app meant for 24.04. Do not do that, just search one for 26.04, if it is available.

I am using Tiling Shell

https://extensions.gnome.org/extension/7065/tiling-shell/

Puppet / Foreman / Ansible for managing servers, and probably for workstations too.

Checkmk / Nagios / Zabbix for monitoring.

FreeIPA for user management.

I am working in company where about 35% of users are on Windows, 40% on Linux and 25% on Mac. In Linux, official way to use MS Office is web apps, but Libreoffice is quite heavily used too.

Wild guess. Libspa version has changed and thus its path too. You will have to put (probsbly new version) of aac.so file to new libspa directory.

Yeah, it might require new one if dependencies have been changed.

Note. Before rebooting, regenerate initramfs for all kernel versions. I am not in debian, but dpkg-reconfigure initramfs-tools might do it.

If you just rename the dir, and then find all broken symlinks in your system?

I had laptop running Ubuntu 16.04, which was running for 2273 days without reboots or anything. It was located in safe place so not even security updates were installed during that time. And it was still completely fine after all these days (little bit over 6 years). It was finally shut down when there was electricity break, and its battery failed, and I decided that it was time to retire it.

There of course were tons of updates available then, but no one forces you to install them. and in Debian system instead of Ubuntu, there will be lot less, their release policy is much stricter.

Also check your bios version. I had similar problems with usb-c and fans on HP Elitebook, they were fixed with bios upgrade.

Edit: I also had troubles waking from sleep. They were caused by wwan/lte modem, I disabled it on bios and now sleep works flawlessly.

For first-time Linux users, I always recommend one of the main user friendly distributions - it is much easier to ask or look for help this way.

So, Fedora, Ubuntu or Opensuse.

Their installers all can live boot

Blog makes valid point, but why on earth there would be any current Linux distribution without usr merge?

EDIT: Especially when every major Linux distributions have already implemented usr merge long time ago.

Ah, I really liked Ubuntu looks in old (4.04 - 8.04) versions. The brown/orange is so much better than the newer gray/purple/red whatever. Since 10.04 the theme and color scheme has been awful.
