```
Starting with `v4.10.0` Telegram has stopped supporting Linux platforms
with `glibc` (GNU C Library) less than `2.29` (`2.28`?):
```shell
> strings Telegram.4.11.3 | fgrep GLIBC_2.2 | tail -1
GLIBC_2.28
```
Linux Mint 19.3 (Tricia) [Ubuntu 18.04 LTS (Bionic Beaver)] ships with `glibc 2.27`:
```shell
> strings /lib/x86_64-linux-gnu/libc.so.6 | fgrep GLIBC_2.2 | tail -1
GLIBC_2.27
```
While modern Telegram might be installed and run by means of `snap` or `flatpak`,
here's the workaround on how to run it on **Linux Mint 19.3 (Tricia)**
[based on **Ubuntu 18.04 LTS (Bionic Beaver)**] w/o "shims" like snap/flatpak:
* Caveats:
* The below example assumes `/opt/glibc-2.29` as a destination directory for Glibc
and auxiliary libs, and `/opt/Telegram.yz` as destination for patched Telegram binary.
Adjust these paths if you'd like to do the things w/o `root` permissions (**which is
a recommended way**).
* Telegram auto-update feature won't be working, meaning you will need to
execute `Download and patch Telegram binary` step each time new version
of Telegram is released
* The `Expat` (XML parsing C library) installation might be a hassle and is not described
in this example as luckily for me it was already installed as a required dependency of
something else installed via `Homebrew`: https://docs.brew.sh/Homebrew-on-Linux
* Sound doesn't work. Need to figure this out (no ideas and cues yet), though I don't
actually listen to audio/video on desktop version.
* :warning: Workarounded this as of now by enabling external video player under experimental
settings under advanced settings menu :shrug:
* :cry: This breaks notification sounds :grey_question: :thinking:
* Download and install Glibc `2.29`:
```shell
cd /tmp/
wget -c https://ftp.gnu.org/gnu/glibc/glibc-2.29.tar.gz
tar -zxvf glibc-2.29.tar.gz
mkdir glibc-2.29/build
cd glibc-2.29/build
../configure --prefix=/opt/glibc-2.29
make
make install
cd ../../ && rm -rf glibc-2.29.tar.gz glibc-2.29/
```
* Provide correct Timezone knowledge to this custom installation of Glibc:
```shell
ln -s /etc/localtime /opt/glibc-2.29/etc/
```
* Link libs required by Telegram into custom Glibc's libs directory
* You may need to adjust source locations of some of the libs and/or
install missing libs if any
* **`libexpat` may become a pain** as it's only `v2.2.5` on this box,
while more modern version is required by Telegram, though happily I'm
a user of `Homebrew` on Linux, that has `Expat` of version `2.5.0`)
