error: cannot communicate with server: Post "http:...

The error you're seeing typically occurs when you're trying to install or run a Snap package (like telegram-desktop) on a Linux system, but the Snap daemon (snapd) isn't running or properly installed.

Here’s how you can fix it:

---

1. Check if snapd is installed

Run:

bash
which snap

If there's no output, you need to install snapd.

To install snapd (for Debian/Ubuntu-based systems):

bash
sudo apt update
sudo apt install snapd

---

2. Start and enable snapd service

After installing:

bash
sudo systemctl enable --now snapd

Check status:

bash
systemctl status snapd

---

3. Create the snapd socket symlink (if missing)

Sometimes the socket path is missing:

bash
sudo ln -s /var/lib/snapd/snap /snap

---

4. Reboot your system

After installing and enabling everything:

bash
sudo reboot

---

5. Retry your command

Once rebooted, try installing or launching again:

bash
sudo snap install telegram-desktop

---

Let me know what distribution you're using if these steps don't work, and I can tailor the instructions accordingly.
