# Removing TemplateVM Packages
When removing any packages from a default TemplateVM, be sure to check what's being removed by `apt autoremove` or `dnf`.
When removing certain packages, for instance Thunderbird, `apt` and `dnf` will attempt to remove many packages required by qubes for the template to function correctly under qubes.
As an example from a terminal in a TemplateVM:
```shell_session
$ sudo apt remove thunderbird
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages were automatically installed and are no longer required:
debugedit libjs-sphinxdoc libjs-underscore librpm3 librpmbuild3 librpmio3
librpmsign3 libsqlite0 linux-headers-4.9.0-6-amd64
linux-headers-4.9.0-6-common linux-image-4.9.0-6-amd64 python-backports-abc
python-cffi-backend python-concurrent.futures python-croniter
python-cryptography python-dateutil python-enum34 python-idna

python-markupsafe python-msgpack python-openssl python-pyasn1 python-pycurl
python-requests python-rpm python-singledispatch python-six python-sqlite
python-sqlitecachec python-tornado python-tz python-urlgrabber
python-urllib3 python-xpyb python-yaml qubes-core-agent-dom0-updates
qubes-core-agent-passwordless-root qubes-gpg-split qubes-img-converter
qubes-input-proxy-sender qubes-mgmt-salt-vm-connector qubes-pdf-converter
qubes-usb-proxy rpm rpm-common rpm2cpio salt-common salt-ssh usbutils yum
yum-utils
Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:
icedove lightning qubes-thunderbird qubes-vm-recommended thunderbird
0 upgraded, 0 newly installed, 5 to remove and 0 not upgraded.
After this operation, 151 MB disk space will be freed.
Do you want to continue? [Y/n]
```
Note all of the qubes packages are tracked as dependencies that will no longer be required. `apt remove` will only remove the packages listed, which is ok.
If, however you also run `apt autoremove` the other qubes packages necessary for TemplateVMs will be removed.
If you'd still like to remove one of these applications without breaking your TemplateVM you have a couple different options.
## Removing Only Packages Not Needed for a Qubes TemplateVM
### Debian
1. In your TemplateVM terminal run:
```shell_session $ apt remove package-name```
Note the packages "no longer required"
2. If the list of "no longer required" packages includes anything beginning with `qubes-` or `salt-` make a note to yourself to **never** run `$ sudo apt autoremove` on this TemplateVM
**Recommended but optional:** Use `apt-mark` to make `apt autoremove` safe again.
```shell_session
$ sudo apt mark-manual package-name package-name
```
Replace package-names with actual `qubes-*` and `salt-*` packages you'd like to retain.
For example, still in your TemplateVM terminal:
```shell_session
$ sudo apt-mark manual qubes-core-agent-dom0-updates qubes-core-agent-passwordless-root qubes-gpg-split qubes-img-converter qubes-input-proxy-sender qubes-mgmt-salt-vm-connector qubes-pdf-converter salt-common salt-ssh qubes-usb-proxy
```
`$ apt autoremove` should now be safe to use.
### Fedora
In your TemplateVM terminal, run:
```shell_session
$ dnf remove --noautoremove package-name
```
## Recovering A TemplateVM which you've already removed needed qubes-* packages
If you've already removed packages, run `apt autoremove` and restarted your VM you've lost passwordless sudo access.
You can login as root, open a terminal in dom0 and run:
```shell_session
$ qvm-run -u root vmname xterm
```
This will open an xterm terminal in the TemplateVM named `vmname`
Once you're logged in as root, reinstall these packages & their dependencies:
### Debian
```shell_session
$ sudo apt install qubes-core-agent-dom0-updates qubes-core-agent-passwordless-root qubes-gpg-split qubes-img-converter qubes-input-proxy-sender qubes-mgmt-salt-vm-connector qubes-pdf-converter salt-common salt-ssh
```
### Fedora
Similar to Debian for example (package names may vary):
```shell_session
$ sudo dnf install qubes-core-agent-dom0-updates qubes-core-agent-passwordless-root qubes-gpg-split qubes-img-converter qubes-input-proxy-sender qubes-mgmt-salt-vm-connector qubes-pdf-converter salt-common salt-ssh
```
